ECE Seminar: Optics, Sensors & AI: Next-Generation Computational Imaging
Fri, Mar 11, 2022 @ 10:00 AM - 11:00 AM

Speaker: Dr. Vivek Boominathan, Postdoctoral Research Associate, Department of Electrical and Computer Engineering, Rice University
Talk Title: Optics, Sensors & AI: Next-Generation Computational Imaging
Abstract: Rapidly growing machine learning techniques such as deep learning have produced powerful computer vision algorithms. However, these algorithms usually apply to images and videos captured with traditional camera designs that have been principally unchanged for decades. Furthermore, real-world applications such as robotics, autonomous navigation, augmented/virtual reality, human-computer interaction, biomedical, and IoT need systems that adhere to fundamental constraints such as size, weight, power, and privacy. These fundamental constraints cannot be addressed by a software-only solution but demand a joint hardware-software solution. In my talk, I will present end-to-end computational imaging systems that execute "computation" at all stages of a physical vision system, from optics to sensors to algorithms. Novel optics such as diffractive and metamaterial optics provide new dimensions of light manipulation, while novel sensors such as SPADs offer new dimensions in light transduction. I will highlight algorithms and AI to explore these new dimensions and accessible nanofabrication techniques to realize novel optics and sensors. I will show applications from photographic 3D imaging to in vivo 3D imaging, achieved using compact coded aperture systems and ultraminiature lensless imaging systems. I will conclude by describing how my works set the stage for designing next-generation imaging systems for various future applications such as biomedical imaging, robotics, IoT, and human-computer interaction.

CS Colloquium: Harsha V. Madhyastha (University of Michigan) - Inter-connecting society across space and time
Fri, Mar 11, 2022 @ 11:00 AM - 12:00 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Harsha V. Madhyastha, University of Michigan
Talk Title: Inter-connecting society across space and time
Series: CS Colloquium
Abstract: Thanks to the Internet and a range of services that have been developed to take advantage of it -- web, email, social media, instant messaging, etc. -- being in the same place at the same time is no longer a requirement for all of us to share information with each other. Instead, we are able to store our ideas, opinions, and observations on services which enable others to access this information later from anywhere in the world.
In this talk, I will discuss my group/s work over the past several years to address some of the fundamental challenges faced by the providers of such global-scale services. I will provide examples of two broad research thrusts: 1) enabling cost-effective development and deployment of geo-distributed services, and 2) optimizing the availability and performance of client-service interactions. I will also briefly discuss my ongoing research in facilitating
information exchange in domains such as web archival, federated learning, and 3D printing.
This lecture satisfies requirements for CSCI 591: Research Colloquium
Biography: Harsha V. Madhyastha is an Associate Professor in CSE at the University of Michigan. His research broadly spans the areas of distributed systems and
networking. Two of his papers have received the IRTF's Applied Networking Research Prize, and he has also co-authored award papers at OSDI, NSDI, and IMC. He has received multiple Google Faculty Research awards, a NetApp Faculty Fellowship, a Facebook Faculty Award, and an NSF CAREER award.

Talk Title: Quantum Information Processing: From Fundamentals to Applications
Abstract: Quantum physics has changed the way we understand nature, and also the way we process information. Starting from the fundamental questions raised a century ago, we have now entered an era of quantum engineering. In this talk, I will introduce our recent results on quantum sensing and communication. Quantum sensing utilizes quantum effects such as coherence, squeezing and entanglement to boost measurement sensitivity. I will summarize the paradigm of distributed quantum sensing, which utilizes multi-partite entanglement to boost the measurement of an arbitrary function of local network parameters, generalizing the famous Heisenberg limit of quantum sensing; distributed quantum sensing has a wide range of applications, including dark matter search in different platforms and quantum machine learning. Then, I will briefly present our recent results on quantum radar and quantum spectroscopy. Finally, I will introduce our works on quantum communication. Claude Shannon established the famous classical capacity of communication channels---the ultimate rate at which classical physics allows us to communicate. Quantum physics has made things more interesting. To begin with, I will introduce our recent works in breaking the Shannon capacity for the first time, by utilizing quantum entanglement; Next, I will briefly summarize works on quantum information transmission, including quantum transduction and quantum repeaters.

Title: Generating and Utilizing Machine Explanations for Trustworthy NLP
Time: Friday, March 11, 3:00PM-5:00PM PST
Committee: Xiang Ren, Robin Jia, Jesse Thomason, Bistra Dilkina, Morteza Dehghani
Abstract:
Neural language models (NLMs) have achieved remarkable success on a wide range of natural language processing (NLP) tasks. However, NLMs sometimes exhibit undesirable behavior, which can be difficult to resolve due to NLMs' opaque reasoning processes. Such a lack of transparency poses serious concerns about NLMs' trustworthiness in high-stakes decision-making.
This motivates the use of machine explanations to automatically interpret how NLMs make decisions. In my thesis proposal, I argue that building human trust in NLP systems requires being able to: (A) generate machine explanations for NLM behavior faithfully and plausibly, and (B) utilize machine explanations to improve language model decision-making.
First, I introduce a framework for optimizing machine explanations w.r.t. both faithfulness and plausibility, without compromising the NLM's task performance. Second, I present an algorithm for regularizing NLMs via machine explanations, in order to improve NLM task performance. Third, I discuss using limited human-in-the-loop feedback on machine explanations to further improve NLMs' generalization ability.
