Title: “Toward a Universal Cryptographic Accelerator”

Abstract:
There have been few high-impact deployments of hardware implementations of cryptographic primitives. We present the benefits and challenges of hardware acceleration of sophisticated cryptographic primitives and protocols, and we describe work on accelerating fully homomorphic encryption using custom hardware by orders of magnitude over multicore CPUs and GPUs. We argue the significant potential for synergistic codesign of cryptography and hardware, where customized hardware accelerates cryptographic protocols that are designed with hardware acceleration in mind. As a concrete example, we present a new design of a zero-knowledge proof (ZKP) accelerator that leverages hardware-algorithm co-design to generate proofs orders of magnitude faster than commodity parallel hardware. In order to mitigate the high cost of designing custom hardware, we propose the design of a universal cryptographic accelerator that can accelerate post-quantum as well as number-theoretic cryptography.

Title: “AI in Highly Regulated Environments: From Data Integrity to Explainability, Benchmarking, and Model‑Risk Management”

Abstract:
AI systems in highly regulated environments must deliver reliability, transparency, and operational safety under demanding real‑world conditions. Particularly, AI models for fraud detection face extreme class imbalance, delayed ground‑truth labels, adversarial behavior, and continuous data drift—making rigorous validation both technically challenging and operationally essential. This seminar presents a reproducible, regulator‑aligned framework for assessing high‑risk AI/ML models, emphasizing data integrity checks, drift diagnostics, and performance stability testing. I will show how surrogate and offset models reconstruct global model behavior when vendor transparency is limited, how segment‑level diagnostics expose under‑performance, and how sensitivity and robustness analyses stress‑test stability under realistic perturbations. The talk concludes with practical strategies for automated validation pipelines, alert‑rate governance, and compensating controls that preserve model reliability while supporting frontline operations. The overarching goal is to illustrate how disciplined validation and model‑risk management enable trustworthy, compliant AI in tightly governed domains.

Title: “Task-Aware Design Optimizations for Analog In-Memory Inference Across Vision and Language”

Abstract:
Analog in-memory computing (AIMC) is a promising compute paradigm to improve speed and power efficiency of neural network inference beyond the limits of conventional von Neumann-based architectures. However, AIMC introduces fundamental challenges such as noisy computations and there lacks a comprehensive understanding of how analog inference generalizes across task domains, precision settings, and architectural scales, and how core design parameters such as cell bits, ADC resolution, and tile size jointly influence model reliability and efficiency. In this talk, we start with benchmarking inference performance of pretrained deep learning models on AIMC simulators. We conduct a comprehensive evaluation of analog inference across both vision and language tasks using three state-of-the-art simulators—CrossSim, AIHWKIT, and MemTorch. Then we systematically quantify how cell precision, ADC resolution, and crossbar tile size influence model accuracy, stability, and efficiency under realistic non-idealities. Results demonstrate that analog inference can achieve within 2–5% of digital baselines when parameters are tuned regarding to layer sensitivity and workload structure. Furthermore, we derive task-aware design guidelines recommendations for vision models and transformer-based NLP tasks based on our findings.

Title: “Exploration of Event-Based Vision Sensors for Autonomous Systems Applications”

Abstract:
At the Collaborative Robots and Agents Lab (CORAL) at TAMUC-CC we are currently exploring multiple applications of event-based camera sensors. We started by exploring the integration of dynamic vision sensors (DVS), and Real-Time Object Detection (RTOD) algorithms. DVS or neuromorphic cameras provide a solution by capturing motion as discrete “events” rather than full-frame images, offering high temporal resolution, low latency, and reduced data bandwidth. Produces visualization data with minimized complexity and throughput. Then, RTOD can be achieved with optimal resource usage accurately and at high speeds. An architecture or sensor fusion framework has been in development to integrate and make the most optimal use of combining diverse vision-based technologies. The framework was preliminary studied for the capabilities of event-based imagers combined with YOLO. Initial experimental work and observations were documented in the utilization of the V2E toolbox that generates realistic synthetic DVS events from intensity frames. The YOLOv12 algorithm is implemented in both the frame and its following raw synthetic DVS event images. At CORAL we currently obtained Prophesee PSK320MPCM2RPI5 GENX320MP-CM2 event-camera module with fixed M6 mount lens (FOV 104°)  and  GENX320MP-CCAM5 chip on board with interchangeable M12 mount lens (FOV 76°) for hands-on experiments to validate and further expand on experiments done with synthetic data. By observing these technologies, confounders and limitations is possible to plan into developing filtering and other documented solutions to fusion these computer vision tools. This research effort aims to develop advanced methods for real-time monitoring in fast changing environments such as autonomous systems-based reconnaissance, structural integrity inspections, law enforcement monitoring, collision avoidance, autonomy T&E and overall tracking, detection, and characterization of objects of interest.

Title: “Designing AI Pipelines for Multimodality in Data-Scarce Medical Systems”

Abstract:
Fully multimodal AI systems are often studied under the assumption of large, well-aligned datasets across modalities, an assumption that rarely holds in real medical environments. Many medical AI applications instead operate in regimes where data are limited, noisy, imbalanced, and only weakly aligned across sources. This talk examines data-scarce medical systems as concrete examples of this regime and focuses on the engineering considerations required to build robust AI pipelines under such constraints. Specifically, the talk begins with task-level model design and development, and then it examines a structural design direction that connects single-modality learning to multimodal expansion by leveraging segmentation outputs as intermediate representations and applying attention-based multi-view integration. These design choices show how system-level decisions shape model behavior and support gradual extension toward multimodality.

Title: “Spatiotemporal Computing Utilizing Dual Thermal Dynamics of Mott Memristors”

Abstract:
The Mott memristor is a highly intriguing device that demonstrates unique electrical characteristics through the dynamic interaction of heat and current. The device exhibits dynamic thermal behavior, encompassing temporal accumulation via heat capacity and spatial transportation through heat diffusion. This spatiotemporal thermal activity enables coupling between memristor devices when arranged in arrays, which can be effectively utilized for computing. Additionally, the thermal dynamics of Mott memristors inherently involve stochasticity, resulting in probabilistic behavior. These properties, such as thermal coupling and stochasticity, provide a novel approach to tackling NP-hard problems, which are often challenging for conventional computers to solve. This presentation explores various computing devices that leverage the spatiotemporal thermal information of Mott memristors, including true random number generators (TRNGs), probabilistic computing systems, and thermal computing devices. The future potential and implications of these technologies will also be discussed.

Maps can be transmitted to ground robots, which use them to validate objects of interest, thanks to a lower vantage point.

 In this talk, we will focus on two significant challenges for heterogeneous teams of robots in the field: communication and perception. First, we will explore opportunistic communications as a paradigm to facilitate large-scale deployment of aerial and ground robot teams. Second, we will discuss applications of neuromorphic sensors such as event cameras for field robotics, showing how these sensors excel in challenging lighting conditions encountered in field applications. Finally, we will address gaps for deploying heterogeneous teams of robots in the field at scale.

Title: “Machine Learning for Hyperspectral Imagery Applications: Trusting Our Models“

Abstract:
Hyperspectral imaging (HSI) comprises a rich source of remote sensing data and is crucial for remote detection of various targets, including gases, liquids, and solids. The advent of deep learning approaches has shown promising results for material detection and identification within long wave infrared (LWIR) HSI. We first introduce the utility of machine learning as a HSI analysis tool, explore the use of physics-guided neural networks as compared to black-box NN models for material classification, and discuss the role of explainability methodology in such analysis. We then discuss the application of 3D scene understanding methods using multiple observations from different angles to create spatially-relevant representations of HSI data, enhancing our ability to characterize targets when obscured by other objects in the scene. We will present results from our analysis pipeline, demonstrating our machine learning approach to the ill-posed inverse problem of material identification and the spectral scaling of neural radiance field (NeRF) models for 3D scene understanding, while also including uncertainty quantification methods to measure associated confidence in our spatial-spectral modeling.

Title: “Texture-Informed Knowledge Distillation from Foundation Models for Efficient Deployment“

Abstract:
Large machine learning models achieve state-of-the-art performance but are often too computationally expensive for deployment in resource-constrained environments. To address this, researchers have turned to knowledge distillation (KD), a widely used method that transfers knowledge from large models into smaller, lightweight student models. However, conventional methods often fail to preserve fine-grained, domain-specific structures that are critical for robust generalization.
In this talk, we will introduce Statistical and Structural Audio Texture Knowledge Distillation (SSATKD), a framework that extends KD beyond prediction and feature-matching by embedding texture awareness into the transfer process. The framework incorporates modules to capture both structural patterns (e.g., periodicity, edges) and statistical properties (e.g., histograms, co-occurrence). By doing so, we enable compact student models to retain domain-relevant signal properties while remaining computationally efficient. We will present results showing that SSATKD improves performance over baseline KD methods in environmental sound tasks and demonstrate the framework’s adaptability to vision through segmentation of scanning electron microscopy images.

Title: “Learning the World in 3D: Real-Time Algorithms and Scalable Data“

Abstract:
3D foundation models are a key step toward spatial and physical intelligence, yet their impact is often constrained by heavy computation and scarce, well-curated 3D data. In this talk, I will present a family of 3D algorithms that make reconstruction, rendering, and generation practical on real workloads, together with a scalable 3D data engine spanning human avatars, Martian-surface simulation, and cryo-EM microscopy.

First, I will cover: (1) city-scale 3D reconstruction and a real-time 3D perception Transformer that operates from uncalibrated images; (2) efficient neural rendering techniques that achieve 60% speedup over 3D Gaussian Splatting while preserving fidelity; and (3) methods by which explicit 3D understanding augments 2D vision–language models to improve spatial awareness prior to reasoning.

Next, I will introduce systematic remedies for 3D data scarcity: (1) an automated pipeline for multimodal human-avatar and environment annotation; (2) a reliable system for simulating Martian surfaces under limited texture availability; and (3) a learned inverse Fourier-slicing map that enables cryo-EM reconstructions up to 10× faster without sacrificing accuracy.

Taken together, these advances move us toward AI systems that interact with the physical world with genuine spatial understanding and real-time performance.

Title: “Dependability and Data Analytics: A Grand Challenge of Our Times”

Abstract:
We live in a data-driven world as we have been realizing for some time. Everything is generating data, in volumes and at high rates, from the sensors embedded in our physical spaces to the large number of machines in data centers being monitored for a variety of metrics. The question that I pose in this talk is:

     Can all this data be used for improving the dependability of our computing systems?

Dependability is the property that a computing system continues to provide its functionality despite the introduction of faults, either accidental faults (design defects, environmental effects, etc.) or maliciously introduced faults (security attacks, external or internal). We have been addressing the dependability challenge through large-scale data analytics applied end-to-end from the small (networked embedded systems, mobile and wearable devices) [e.g., MobiSys-25, Security & Privacy-24, CVPR-24, 23, 22, TODAES-23, Eurosys-22] to the large (edge and cloud systems, distributed machine learning clusters) [e.g., NeurIPS-25, 22, UAI-25, CCS-24, Security & Privacy-24, ICLR-24, Middleware-23, OSDI-22, Sigmetrics-22]. In this talk, I will first give a high-level view of how data analytics has been brought to bear on dependability challenges, and key insights and achievements from our technical community. Then I will provide details of three projects where we design systems from the small to the large, to meet dependability and performance requirements, using data-driven decisions.

For the detailed part, I will discuss the following projects: (I) Small: Streaming LiDAR analytics on autonomous vehicles; (II) Small-to-Medium: Sensor-edge-cloud continuum; (III) Small-to-Medium: Secure decentralized learning. I will provide enough background and intuition in each, so that the talk is accessible to a broad CS audience.

The presentation incrementally complexifies hardware design, from external FPGA AVs to the redesign of the memory controller. The talk discusses ideas like adding new Memory Management Unit (MMU) flags to create a new type of page fault – the security fault – to create security-aware OSes that invoke AntiViruses (AVs) on demand to scan processes in more suitable states. Dr. Botacin’s research talk will highlight how AVs can be significantly enhanced by relying on additional hardware support and will call for action to advance their development.

Title: “From Robots that React to Robots that Adapt”

Abstract:
Achieving truly autonomous robotic systems that can adapt to unknown environments and collaborate using natural language requires a fundamental shift beyond the traditional “sense-think-act” paradigm. In this talk, I will advocate for a holistic framework centered on active perception, where perception, reasoning, and action are tightly integrated into a unified loop. This approach is key to developing resilient, adaptive robots capable of operating in novel and unstructured settings. We will explore the interplay between perceptual geometry, semantics, and action within this paradigm. The first part of the talk explores perception-aware planning and the necessity for coupling the problem for perceptual degradation. The latter half focuses on how foundation models for embodied AI can enable scalability and generalization. A crucial aspect of this discussion is the challenge of translating natural language into actionable information — determining what to map, which areas to explore, and how to represent knowledge in a way that remains scalable while retaining task relevance. Additionally, I will discuss hierarchical architectures that support effective decision-making across diverse contexts and how to build guardrails on inferred actions from foundation models to ensure responsible and safe autonomy. By addressing these challenges, we move toward adaptive, resilient, and responsible robotic systems that can function collaboratively with humans and other robots at scale. This vision lays the groundwork

Title: “Programming the Network and the Environment for Sensing, Communication and Computation”

Abstract:
This presentation delves into how extreme reconfigurability will shape future wireless networks, made possible by exciting new developments in the areas of open radio access networks (O-RAN) and reconfigurable intelligent surfaces (RIS). By embracing programmability at all levels, from centralized cellular architectures to distributed network components, such wireless networks will not only establish resilient communication links but also perform sensing tasks to better perceive and, to an extent, even engineer the surrounding environment. In this two-part talk, we first describe how “programmable networks” in the form of O-RAN-compliant base stations can evolve their roles from sensing weak radar signals to performing automated network traffic analysis followed by resource allocation. In the second part of the talk, we shift towards “programmable environments” where we experimentally demonstrate how custom-designed RIS can be used for channel hardening in single antenna receivers by intentionally creating multipath diversity. We also explore how such programmability opens a new domain of wireless computing, where transmitted signals can be used to perform mathematical operations by leveraging the physics of over-the-air propagation. A common theme in programming both the “network” and “environment” is rigorous experimental validation on laboratory and field-deployed systems.

Title: “Distributed AI in Networked Systems: A Graph-Based Neuro-Symbolic Perspective”

Abstract Artificial intelligence has achieved remarkable success in processing regular, unstructured data, such as language and images, where information is supported on structured grids (tokens in 1D sequences, pixels in 2D grids). However, networked systems—such as communication networks, transportation and logistics systems, and fog/edge/cloud computing—pose fundamentally different challenges for standalone AI. These systems involve parallel and rule-based operations, irregular and dynamic structures, and real-time, high-stakes decision-making, rendering standalone AI systems insufficient. This talk explores graph-based neuro-symbolic approaches that incorporate domain knowledge to enable AI adhere to rules and protocols, learn and adapt with smaller models and less training data, while remaining scalable and interpretable. I will first introduce graph neural networks (GNNs) as a universal workhorse for learning from graph-structured data. Next, we will dive into graph-based deterministic policy gradient (GDPG), a general framework that enhances rather than replaces domain-specific heuristics with GNNs. Using link scheduling in self-organizing wireless networks as an example, we will explore how this approach can tackle key challenges in networked systems—real-time constraints, combinatorial decision spaces, lack of labeled data, and the need for scalability and interpretability. This talk will conclude with an overview of recent advances, potential applications, and broader implications of this framework, including its relevance to biological networks (e.g., protein interaction networks), adaptive traffic signal control, and knowledge graphs.

Title: “AI for Science: From Microscopic Structures and Dynamics to Macroscopic Functions”

Abstract
The evolution of scientific discovery has transitioned from observational studies and mathematical modeling to data-driven AI methodologies. With the rapid advancement of deep learning and neural network architectures, AI has become a powerful tool for accelerating scientific discovery. However, as large-scale models exhibit emergent behaviors, understanding the structural and dynamic principles that govern these models is crucial.

In this talk, I will discuss Neuron-based Multifractal Analysis (NeuroMFA), a novel framework that bridges AI and scientific discovery by characterizing the self-organization of large models. Inspired by neuroscience, NeuroMFA provides a structural perspective on emergent intelligence in AI, offering insights into how deep neural networks develop complex functionalities. This approach enables a deeper understanding of AI’s role in science and facilitates advancements in areas such as material discovery, physics-informed machine learning, and computational neuroscience.

Title: “The Rise and Fall of Machine Learning for EDA and Beyond – Studies in Synthesis and Verification”

Abstract
In recent years, Machine Learning (ML) has gained considerable momentum in electronic design automation (EDA). Specifically, the successes of ML-driven EDA methods and infrastructure have demonstrated its unique capability in capturing the multitude of factors affecting estimation accuracy, effectively exploring large algorithmic and design spaces in synthesis, and accelerating classical combinatorial optimization problems. In particular, synthesis and verification, critical stages in EDA, have significantly benefited from ML in the last five years. However, during the development of ML-driven synthesis and verification approaches, several points of convergence have been observed, including practicality, system engineering challenges, data availability, and determinism. In this talk, I will present the journey of exploring ML in synthesis and verification, focusing on discussing the evolutionary developments from static ML-based synthesis approaches to algorithmic learning and general combinatorial optimizations using advanced domain-specific ML techniques. The talk will primarily focus on our recent work in high-level synthesis, logic synthesis, and Boolean reasoning.

Title: “Enable Efficient Bayesian Optimization with Semi-Supervised Learning and In-Context Learning of Large Language Models”

Abstract
Bayesian Optimization (BO) is a powerful framework for optimizing expensive black-box functions, but its efficiency is often hindered by two key challenges: (1) difficulties in encoding domain knowledge and (2) data scarcity that limits surrogate model generalization. In this talk, I will present the recent efforts from our group to address these challenges.

First, we introduce ADO-LLM, which leverages the domain priors of Large Language Models (LLMs) to assist BO in tackling the challenging analog circuit sizing problem. By proposing feasible and high-potential design parameters, LLMs enable BO to efficiently explore design spaces while balancing complex tradeoffs between design specifications.

Second, we discuss TSBO, a method that enhances BO’s data efficiency in high-dimensional settings by strategically incorporating unlabeled samples and generating reliable pseudo-labels via a teacher-student model with feedback. TSBO demonstrates strong performance across multiple high-dimensional BO tasks, achieving up to a 364.2x reduction in labeled data usage.

Finally, I will conclude with a discussion on the broader implications and future directions for data-efficient BO.

Title: “Provenance Attestation: From Silicon Chips to Biological Cells and Beyond”

Abstract
Complex processes, whether natural or artificial, often exhibit inherent variability and result in slightly different products even when identical steps, equipment, materials and conditions are employed. Such variability typically consists of a random component, which is attributed to the endogenous stochasticity of the process itself, and a systematic component, which is attributed to the exogenous aspects of the production. In this presentation, we will discuss how this variability can be harnessed for the purpose of attesting both the process and each copy of the product, thereby facilitating trust, traceability and intellectual property protection. First, in the context of semiconductor manufacturing, using both physical and electrical measurements (a.k.a., metrology and wafer acceptance tests, respectively) from wafers manufactured using multiple copies of a mask-set in a 12nm GlobalFoundries technology, we will demonstrate the use of contemporary statistical and machine learning-based methods for determining whether a wafer was produced by a ratified mask-set. Leveraging the insight gained through this analysis, we will also discuss the design of custom sensors for obtaining the relevant information from each die on a wafer to collectively attest the mask-set used to produce this wafer, without relying on potentially untrusted foundry-provided data. Then, in the context of synthetic biology, using amplicon sequencing data from multiple cell lines (i.e., HEK293, HCT116 and HeLa), we will demonstrate that the stochasticity of the non-homologous end-joining (NHEJ) DNA repair process can be leveraged as a mechanism for introducing a unique identifier (i.e., a Genetic Physical Unclonable Function (PUF)) in every legitimately produced copy of a cell line. Akin to their counterparts in the semiconductor industry, Genetic PUFs can be used for attesting the provenance and protecting the intellectual property of valuable, genetically-engineered cell lines.

Title: “DeepOSets: Non-Autoregressive In-Context Learning of Supervised Learning Operators” 

Abstract
We introduce DeepSets Operator Networks (DeepOSets), an efficient, non-autoregressive neural network architecture for in-context learning of permutation-invariant operators. DeepOSets combines the operator learning capabilities of Deep Operator Networks (DeepONets) with the set learning capabilities of DeepSets. Here, we present the application of DeepOSets to the problem of learning supervised learning algorithms, which are continuous permutation-invariant operators. We show that DeepOSets are universal approximators for this class of operators. In an empirical comparison with a popular autoregressive (transformer-based) model for in-context learning of linear regression, DeepOSets reduced the number of model weights by several orders of magnitude and required a fraction of training and inference time, in addition to significantly outperforming the transformer model in noisy settings. We also demonstrate the multiple operator learning capabilities of DeepOSets with a polynomial regression experiment where the order of the polynomial is learned in-context from the prompt.

Title: “Synthesizing Provably Performant Controllers for Networked Systems” 

Abstract
Computer systems rely on various controllers to allocate CPU, memory, network and storage resources. The quality of their decision making significantly impacts system performance, sometimes degrading it by over 10x. Poor controller decisions also lead to performance variability that makes it difficult to build real-time applications and highly distributed computations. Controller design is hard due to incomplete system observability and the lack of an accurate system model. This makes it difficult to formally define, let alone guarantee, desired performance properties. As a result, these controllers are designed largely through empirical trial-and-error.

In this talk, I will discuss a set of principles and tools that we have developed to not only verify, but also synthesize controllers with provable performance guarantees. I will focus on the controllers involved in low-latency video streaming and show how program synthesis techniques can uncover novel solutions overlooked by human designers for decades.

Title: “Computer Architecture Research: Moving the Needle” 

Abstract
After almost 60 years in the trenches performing microarchitecture research, I have some thoughts about what it takes to move the needle.  Most importantly, one must understand the hardware details that the microarchitecture is built on, and the details of the resulting microarchitecture.  Re: bottom-up or top-down, at least avoid being a top-up.  If you have a burning desire to add a feature, choose the microarchitecture, not the ISA. Understand heterogeneity and why it is almost certainly the answer.  Celebrate MIT’s proclamation that there is plenty of room at the top and my suggestion that there is still plenty of room at the bottom.  Recognize that there may be more than one obstacle in place so your improvement may not pay off until the last obstacle has been conquered.  Finally, be generous in your praise for the work of others.  You are not the only smart person in the room.  In this talk, I hope to expand on many of the points mentioned above.

Title: “Deep Learning for Smarter Algorithms in Detection, Estimation, and Navigation” 

Abstract
By deploying deep learning methods as global optimizers that learn algorithms, we can solve long-standing ill-posed problems in joint parameter estimation. Neural networks can also produce human-interpretable results that de-mystify the algorithm design process, allowing us to rigorously determine hyperparameters such as training lengths. I will introduce two recent works where this methodology is used to tackle open problems in remote sensing and navigation. In underwater environment estimation, I will present a U-Net method for the acoustic mapping of reflective boundaries such as the sea surface and seafloor, with state-of-the-art performance and the new capability of jointly estimating the number of boundaries in the environment. In the field of robotic path planning, I will present a recurrent convolutional neural network (RCNN) method for solving Obstacle Avoiding Rectilinear Steiner Minimum Tree (OARSMT) problems. By learning an algorithm via reinforcement learning, whose intermediate stages are visible to the user, we devise augmentations that yield strong accuracy and runtime performances, which can lead to lower power consumption. Beyond their immediate applications, these new methods point to a general strategy of solving a broad class of joint parameter estimation problems via deep learning.

Title: “Distributed No-Regret Learning for Multi-Stage Systems with End-to-End Bandit Feedback” 

Abstract
This talk focuses on multi-stage systems with end-to-end bandit feedback. In such systems, each job needs to go through multiple stages, each managed by a different agent, before generating an outcome. Each agent can only control its own action and learn the outcome of the job. It has neither knowledge nor control on actions taken by agents in the next stage. The goal of this paper is to develop distributed online learning algorithms that achieve sublinear regret in adversarial environments.

The setting of this paper significantly expands the traditional multi-armed bandit problem, which considers only one agent and one stage. In addition to the exploration-exploitation dilemma in the traditional multi-armed bandit problem, we show that the consideration of multiple stages introduces a third component, education, where an agent needs to choose its actions to facilitate the learning of agents in the next stage. To solve this newly introduced exploration-exploitation-education trilemma, we propose a simple distributed online learning algorithm, ϵ−EXP3. We theoretically prove that the ϵ−EXP3 algorithm is a no-regret policy that achieves sublinear regret. Simulation results show that the ϵ−EXP3 algorithm significantly outperforms existing no-regret online learning algorithms for the traditional multi-armed bandit problem.

Senior Research Scientist in Storage Analytics

Title: “Data-Driven IO Modeling and Optimizations in Cluster Storage Systems” 

Abstract
In this talk, I will cover two recent data-driven research projects in cluster storage systems — Thesios and Morph. Thesios is a methodology to accurately synthesize full-resolution representative IO traces, and counterfactual “what-if” traces by carefully combining down-sampled IO traces collected from multiple disks attached to multiple storage servers. Representative traces help inform the design and configuration of storage systems on real-world workloads, and counterfactual traces help assess the impact of anticipated or hypothetical new storage policies or hardware prior to deployment. I will also discuss the usefulness of Thesios for academia in order to obtain real-world traces, and the experience in open-sourcing synthesized traces comprising 2.5 billion IO requests.

Morph is the data-driven redundancy adaptation of files stored in cluster storage systems, over their lifetimes to address changes in data temperature and latency requirements. For newly ingested data, commonly stored via 3-way replication, Morph introduces a hybrid redundancy scheme that combines a replica with an erasure coded (EC) stripe, reducing both ingest IO and capacity overheads while enabling free transcode to EC by deleting replicas. For subsequent transcodes to wider, more space-efficient EC configs, Morph exploits Convertible Codes, which minimize data read for EC transcode, and introduces new block placement policies to maximize their effectiveness. Morph is thus designed to optimize redundancy by taking a file-lifetime view and minimizing IO overheads without affecting performance.

Title: “Planning and Control Problems in Robotics for Manufacturing Operations” 

Abstract
There has been a significant growth in the use of articulated robots for automation of manufacturing operations across many industrial sectors, including aerospace, transportation, construction, electronics, etc., with applications ranging from assembly, surface finishing, to material handling and delivery. For example, mechanical surface finishing operations, such as grinding, sanding, polishing, chamfering, etc., are widely employed in many industrial sectors to remove part anomalies and achieve a desired surface finish. Surface finishing has predominantly been a manual operation that is highly labor intensive and requires skilled operators. The key benefits of integrating robots into these environments include consistent surface quality, improved productivity, preventing hazardous exposure to vibration and particulate, significant flexibility for small as well as large batch manufacturing of finished parts, and the potential for re-purposing the robot quickly to adapt to a new part.

One can find many recent research and technology development activities focusing on the technical challenges of integrating robots into these operations in various environments. This talk will provide an overview of some of the essential elements, challenges, and recent advances in integrating robots to improve manufacturing operations, including registration of the workpiece in the robot workspace, path planning and control. A portion of the talk will also discuss some recent work on the benefits and challenges of V2V communication in connected and autonomous vehicles.

The emergence of Large Language Models (LLMs) has transformed how we apply Machine Learning (ML) in the field of semiconductor test. Recent advancements in LLMs showcase their impressive ability to engage in meaningful dialogue across a wide range of topics, answer complex questions, and even generate code.

In this talk, I will share our experience in harnessing the power of LLMs to develop an AI agent specifically for semiconductor test data analytics. Our approach centers on the integration of a Knowledge Graph (KG) advocate for an end-to-end methodology that positions the KG as a critical component. I will introduce a novel paradigm, Decision-Support ML (DSML), and explain its implementation in common test data analytics workflows. Using wafermap analytics as a case study, we have demonstrated how we built IEA-Plot, an LLM-assisted AI solution, by leveraging typical LLM functionalities. I will show the real-world application of IEA-Plot on test data collected from a recent production line.

Title: “Using Generative AI Technology to Transform Customer Support Services” 

Abstract
Agent Assist is a software tool, that enables remote technical support agents solve clients’ problems faster and helps newly hired support agents increase their productivity and reduce the time required to learn and resolve cases. Agent Assist integrates tightly with the IBM Cognitive Support Platform (CSP), the tool that IBM support agents use to troubleshoot customer cases. It receives a real-time notification from CSP every time a new case is opened and pushes back to CSP recommendations for resolving that case, based on analysis of past, resolved, similar cases and relevant product documentation. Agent Assist leverages watsonx.ai for retrieving similar historical cases and for past case resolution extraction and summarization, using generative large language models (LLMs). It achieves fast response of less than 60 seconds end-to-end by performing most time-consuming LLM and indexing operations offline.

The transformation of customer support service into a more automated and efficient business by the use of AI is strategic for many businesses, promising higher efficiency, lower cost of operation and improved customer satisfaction. The Agent Assist technology is enabling and accelerating this transformation by harnessing the power of generative AI and by scaling across multiple Support products and functions.

Title: “BaM: System Architecture and Software Stack for Accelerating Compute-Directed Access to Massive Datasets”

Abstract
Compute Devices have traditionally relied on OS services to bring data into the memory in bulk before performing algorithmic computation on the individual data-structure elements. For example, Graphics Processing Units (GPUs) have relied on the host CPU services to bring chunks of storage data into its device memory for use by compute kernels. This approach is well-suited for GPU applications with known data access patterns that enable partitioning of their dataset to be processed in a pipelined fashion in the GPU. However, emerging applications such as graph and data analytics, recommender systems, and graph neural networks, require fine-grained, data-dependent and sparse access to vast feature vectors and embedding datasets. CPU services are unsuitable for these applications due to high CPU-GPU synchronization overheads, I/O traffic amplification, and low CPU software throughput. GPU-initiated access avoids these overheads by removing the CPU from the storage control path and, thus, can potentially support these applications at much higher speed. However, there is a lack of systems architecture and software stack that enable efficient GPU-initiated storage access for applications today. I will present a vision for enabling fast, compute-directed sparse access to massive datasets, the BaM system architecture to realize this vision, and the BaM software stack that efficiently supports emerging applications on existing and upcoming GPUs.

Title: “Structured Reinforcement Learning in NextG Cellular Networks”

Abstract
NextG cellular networks face increasing demands for intelligent control, especially with the advent of softwarized Open Radio Access Networks (O-RAN) and diverse user applications. We present EdgeRIC, a real-time RAN Intelligent Controller (RIC) co-located with the Distributed Unit (DU) in the O-RAN architecture, enabling sub-millisecond AI-optimized decision-making. We propose a constrained reinforcement learning (CRL) approach for developing such real-time strategies, showing that these algorithms can be trained with only a logarithmic increase in complexity compared to traditional RL. We introduce structured learning using threshold and Whittle index-based policies, which provides low-complexity learning and scalable, real-time inference for optimizing resource allocation and enhancing user experience. For media streaming, we prove the optimality of a threshold policy and develop a soft-threshold natural policy gradient (NPG) algorithm that prioritizes clients based on video buffer length, achieving inference times of about 10μs and improving user quality of experience by over 30%. Additionally, we leverage Whittle indexability to simplify resource allocation, ensuring service guarantees such as ultra-low latency or high throughput by training neural networks to compute constrained Whittle indices. Our Whittle index approach, implemented on EdgeRIC, achieves allocation decisions within 20μs per user, enhancing service guarantees across standardized 3GPP service classes, making a case for structured, scalable reinforcement learning for real-time control of NextG networks.
