ESE PhD Thesis Defense: “Toward High-performance Simple Models of Legged Locomotion”
This thesis addresses the challenges of model-based planning and control in legged locomotion, particularly the trade-off between computational speed and robot performance presented by different levels of model complexities. Full-order […]
MSE Seminar: “Turbo-charging Silicon: Do we have the materials and devices?” (Deep Jariwala) University of Pennsylvania
Silicon has been the dominant material for electronic computing for decades and very likely will stay dominant for the foreseeable future. However, it is well-known that Moore’s law that propelled […]
ESE Fall Seminar – “Magnetic technologies for battery-free bioelectronics and neuromodulation”
Miniature implanted and injected technologies capable of manipulating and recording biological signals promise to improve the way we study biology and the way we diagnose and treat disease; however, to […]
ESE Fall Seminar – “Electromagnetics for advanced power electronics and wireless power transfer”
Power electronics is an essential enabler for efficient energy utilization across many different applications as well for renewable electricity generation. Advances in power semiconductor materials and devices are improving power […]
ESE Fall Seminar – “Stochastic Geometry for Networks”
Stochastic geometry is a branch of probability theory that deals with the study of random spatial patterns. Random point patterns, termed point processes, are the most basic such objects that […]
ESE Fall Seminar – “Approximate symmetries in machine learning”
In this talk, we explain different roles that symmetries and approximate symmetries can play in machine learning models. We define approximately equivariant graph neural networks and we show a bias-variance […]
ESE Fall Seminar – “Quantum sensing and imaging with diamond spins”
Solid state spin qubits, in particular the nitrogen vacancy (NV) center in diamond, offer a path towards truly nanoscale imaging of condensed matter and biological systems with sensitivity to single […]
ESE Fall Seminar – “Acceleration by Stepsize Hedging”
Can we accelerate convergence of gradient descent without changing the algorithm — just by optimizing stepsizes? Surprisingly, we show that the answer is yes. Our proposed Silver Stepsize Schedule optimizes […]
ESE Fall Seminar – “Agile Design of Domain-Specific Accelerators and Compilers”
With the slowing of Moore’s law, computer architects have turned to domain-specific hardware accelerators to improve the performance and efficiency of computing systems. However, programming these systems entails significant modifications […]
ESE Fall Seminar – “Large Observational Study of the Causal Effects of a Nudge and the Geometry of Causality”
Nudges are interventions promoting healthy behavior without forbidding options or significant incentives. As an example of a nudge, the Apple Watch encourages users to stand by delivering a notification if […]
