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.

Title: “Hardware is the New Software: The Next-Gen Anti-Viruses and How Your Hardware Will Self-Secure Your System!”

Abstract:
New threats require new defenses. In the same way that LLMs are reshaping malware creation, hardware support for security should be reshaping defenses. In this talk, Dr. Botacin presents the proposal for the migration of AV engines to hardware to implement continuous monitoring systems (Zero-Trust) with low performance impact. 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

Sanjay Shakkottai
Professor of ECE and Director of Center for Generative AI
University of Texas, Austin

Title: “Training-Free Approaches for Image Inversion and Editing Using Latent Generative Models”

Abstract:
Diffusion-based generative models transform random noise into images; their inversion aims to transform images back to structured noise that is suitable for recovery and editing. In this talk, we present Reference-Based Modulation (RB-Modulation), a plug-and-play solution for training-free editing and stylization of diffusion models. Existing training-free approaches exhibit difficulties in (a) style extraction from reference images in the absence of additional style or content text descriptions, (b) unwanted content leakage from reference style images, and (c) effective composition of style and content. RB-Modulation is built on a novel stochastic optimal controller where a style descriptor encodes the desired attributes through a terminal cost. The resulting drift not only overcomes the difficulties above, but it also ensures high fidelity to the reference style and adheres to the given text prompt. We also introduce a cross-attention-based feature aggregation scheme that allows RB-Modulation to decouple content and style from the reference image. Next, we study inversion and image editing using Rectified Flow (RF) models (such as Flux, the current state-of-art model for image generation). We present RF-Inversion using dynamic optimal control derived via a linear quadratic regulator. We show that the resulting vector field is equivalent to a rectified stochastic differential equation. Additionally, we extend our framework to design a stochastic sampler for Flux. Our inversion method allows for state-of-art performance in zero-shot inversion and editing, outperforming prior works in stroke-to-image synthesis and semantic image editing, with large-scale human evaluations confirming user preference.

Title: “SGD and Weight Decay Secretly Compress Your Neural Network”

Abstract:
Several empirical results have shown that replacing weight matrices with low-rank approximations results in only a small drop in accuracy, suggesting that the weight matrices at convergence may be close to low-rank. In this talk, we will explore the origins of the bias in Stochastic Gradient Descent (SGD) that leads to learning low-rank weight matrices when training neural networks. Our findings demonstrate that training neural networks with SGD and weight decay introduces a bias toward rank minimization in the weight matrices. We theoretically and empirically show that the rank of the weight matrices is controlled by the batch sizes, learning rate, and the amount of regularization. Unlike prior work, our analysis does not rely on assumptions about the data, convergence, or optimality of the weight matrices and applies to a broad range of neural network architectures, regardless of width or depth. Finally, we will discuss the connections between our analysis and other related properties, such as implicit regularization, generalization, and compression. This is joint work with Zachary Siegel, Aparna Gupte, and Tomaso Poggio.

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.

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.

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.

Title: “The Challenges and Opportunities in the Mobility Electrification“

Abstract
The electrification of mobilities is essential for sustainability, and governments are pushing hard to expedite electric vehicle penetration. As a result, many electric vehicles on the road are present today. Nevertheless, the battery industry faces significant challenges starting in late 2023, which will continue for years. In this talk, we will introduce industry perspective challenges and opportunities for mobility electrification in both the technical and business aspects. The technical aspects to be covered are automotive battery requirements such as energy density, charging time, lifetime, cost, and safety. We will talk about the infrastructure issues for electric vehicle charging. As for the business aspects, we will discuss the vehicle electrification roadmap, government support, marketing challenges, cost demands, battery raw material costs, etc. This talk is the first to introduce battery technical evolution in the context of “Battery Technology Scaling,” analogous to semiconductor technology scaling. We will also summarize the expected academic contributions to the electrification of mobilities.
