CESG Seminar: Dr. Awais Altaf

Posted on May 17, 2022 by Vickie Winston

Thursday, June 2, 2022
10:00 – 10:50 a.m. (CST)
ETB 1035 – **In-person**

Dr. Muhammad Awais Bin Altaf
Assistant Professor, Electrical Engineering
Lahore University of Management Sciences (LUMS), Pakistan

Title: “On-Chip Energy-Efficient Neural Diagnostics: Advancing Neuroscience through Wearable Devices”

Talking Points:

  • Wearable Healthcare
  • On-Chip Energy Efficient Digital Processing Techniques for ML algorithms
  • Early Detection of Negative Emotion Outburst

Abstract
Artificial intelligence (AI) has influenced all aspects of human life and neurology is no exception to this growing trend. Today, neurology faces multiple challenges in the field of diagnostic and management modalities. This ranges from simple issues like identification of healthy sleep patterns to more complicated issues like early detection and reduction in the duration of rehabilitation of acute ischemic stroke diagnosis of rare subtypes of epilepsy. The increasing availability and progress of analytical techniques are opening new doors in health care. Machine learning, neural networks and other AI tools are used to classify the patient’s electroencephalogram (EEG) data to help neurologists in making an early diagnosis and improving care. Hence, the development of ultra-low-power System-on-Chip (SoC) for the next generation of the neuro-wearables, in the realms of detecting, diagnosing, and even preventing irreversible outcomes due to neurological disorders is essential. The uptake in the use of neuro-wearable technology by both patients and clinicians will have a huge impact on the future of healthcare.

This talk will cover the design strategies of energy-efficient patient-specific SoC biomedical devices. I will first explore the challenges, limitations and potential pitfalls in wearable interface circuit design, and strategies to overcome such issues. Moreover, I will describe on-chip energy-efficient digital processing techniques for the implementation of machine-learning algorithms for disease detection focusing on the negative emotion outburst early detection in Autistic patients. The talk will conclude with interesting aspects and opportunities that lie ahead.

CESG Seminar: Dr. Bo Yuan

Posted on January 25, 2022 by Vickie Winston

Friday, January 25, 2021
4:10 – 5:00 p.m.
via Zoom (link below)
 
Dr. Bo Yuan
Asst. Professor, Dept. of Electrical & Computer Engineering, Rutgers University

Title: “Algorithm and Hardware Co-Design for Efficient Deep Learning: Sparse and Low-rank Perspective”

Talking Points

  • Algorithm and hardware co-design for structured and unstructured deep neural networks
  • Algorithm and hardware co-design for high-order tensor decomposition-based deep neural networks

Abstract
In the emerging artificial intelligence era, deep neural networks (DNNs), a.k.a. deep learning, have gained unprecedented success in various applications. However, DNNs are usually storage intensive, computation intensive and very energy consuming, thereby posing severe challenges on the future wide deployment in many application scenarios, especially for the resource-constraint low-power IoT application and embedded systems. In this talk, I will introduce the algorithm/hardware co-design works for energy-efficient DNN in my group, from both the sparse and low-rank perspectives. First, I will show the benefit of using structured and unstructured sparsity of DNN for designing low-latency and low-power DNN hardware accelerators. In the second part of my talk, I will present an algorithm/hardware co-design framework that leverages low tensor rankness towards energy-efficient high-accuracy DNN model and accelerators.

Title: “Waymo Self Driving: An Overview”

Talking Points

    • Self-driving is driven by corner cases
    • Sensor fusion is important; but independence is more useful
    • No problem is too simple

Abstract
We will first give an overview of Waymo, the “Waymo Driver” and the vision for Self-Driving systems we have under development. We will then take a closer look at the current generation vehicle from a technical standpoint and delve into the sensor systems and modalities onboard (radar, laser, camera, IMU’s and microphones(!)). That will lead to a discussion of higher level system architecture (hardware and software) and the safety framework that underpins the system. Finally we will wrap up with some observations from the field regarding differences between research, development and deployment of complex systems like self-driving vehicles.

CESG Seminar: Dr. Mayank Parasar

Posted on January 14, 2022 by Vickie Winston

Friday, March 25, 2022
4:10 – 5:00 p.m.
ETB 1020 – *In-person* (Emerging Technologies Building)
Dr. Mayank Parasar
Samsung Austin R&D Center (SARC) in Austin, TX

Title: 
“Subactive Techniques for Guaranteeing Routing and Protocol Deadlock Freedom in Interconnection”

Talking Points:

    • Correctness is of paramount concern in interconnection networks. (Routing and Protocol) Deadlock freedom is a cornerstone of correctness.
    • Prior solutions either over-provision the network or incur performance penalty to provide deadlock freedom
    • We propose new set of unified techniques to resolve routing and protocol deadlocks

Abstract
Interconnection networks are the communication backbone for any system. They occur at various scales: from on-chip networks, for example 2.5D/chiplet networks, between processing cores, to supercomputers between compute nodes, to data centers between high-end servers. One of the most fundamental challenges in an interconnection network is that of deadlocks. Deadlocks can be of two types: routing level deadlocks and protocol level deadlocks. Routing level deadlocks occur because of cyclic dependency between packets trying to acquire buffers, whereas protocol level deadlock occurs because the response message is stuck indefinitely behind the queue of request messages. Both kinds of deadlock render the forward movement of packets impossible leading to complete system failure.

Prior work either restricts the path that packets take in the network or provisions an extra set of buffers to resolve routing level deadlocks. For protocol level deadlocks, separate sets of buffers are reserved at every router for each message class. Naturally, proposed solutions either restrict the packet movement resulting in lower performance or require higher area and power.

We propose a new set of efficient techniques for providing both routing and protocol level deadlock freedom. Our techniques provide periodic forced movement to the packets in the network, which breaks any cyclic dependency of packets. Breaking this cyclic dependency results in resolving routing level deadlocks. Moreover, because of periodic forced movement, the response message is never stuck indefinitely behind the queue of request messages; therefore, our techniques also resolve protocol level deadlocks. We use the term ‘subactive’ for these new class of techniques.
