SUMMARY:CS Seminar Series: Iris Bahar\, Brown University – “Accurate\, Real-time Energy-efficient Scene Perception through Hardware Acceleration”
DESCRIPTION:LocationZoom: https://wse.zoom.us/j/95216049470AbstractTechnological advancements have led to a proliferation of robots using machine learning systems to assist humans in a wide range of tasks. However\, we are still far from accurate\, reliable\, and resource-efficient operations of these systems. Despite the strengths of convolutional neural networks (CNNs) for object recognition\, these discriminative techniques have several shortcomings that leave them vulnerable to exploitation from adversaries. In addition\, the computational cost incurred to train these discriminative models can be quite significance. Discriminative-generative approaches offers a promising avenue for robust perception and action. Such methods combine inference by deep learning with sampling and probabilistic inference models to achieve robust and adaptive understanding. The focus is now on implementing a computationally efficient generative inference stage that can achieve real-time results in an energy efficient manner. In this talk\, I will present our work on Generative Robust Inference and Perception (GRIP)\, a discriminative-generative approach for pose estimation that offers high accuracy especially in unstructured and adversarial environments. I will then describe how we have designed an all-hardware implementation of this algorithm to obtain real-time performance with high energy-efficiency.Bio \nIris Bahar received the B.S. and M.S. degrees in computer engineering from the University of Illinois\, Urbana-Champaign\, and the Ph.D. degree in electrical and computer engineering from the University of Colorado\, Boulder. Before entering the Ph.D program at CU-Boulder\, she worked for Digital Equipment Corporation on their microprocessor designs. She has been on the faculty at Brown University since 1996 and now holds a dual appointment as Professor of Engineering and Professor of Computer Science. Her research interest have centered on energy-efficient and reliable computing\, from the system level to device level. Most recently\, this includes the design of robotic systems. Recently\, she served as the Program Chair and General Chair of the International Conference on Computer-Aided Design (ICCAD) in 2017\, 2018 respectively and the General Chair of the International Conference on Architectural Support for Programming Languages and Operating Systems (ASPLOS) in 2019. She is the 2019 recipient of the Marie R. Pistilli Women in Engineering Achievement Award and the Brown University School of Engineering Award for Excellence in Teaching in Engineering.
