ESE Fall Seminar – “Tools for designing some exciting chips”

Berger Auditorium (Room 13), Skirkanich Hall 210 South 33rd Street, Philadelphia, PA, United States

There is an enormous interest in developing customized, domain-specific systems-on-a-chip.  Continued improvement in computing efficiency requires functional specialization of hardware designs. But designing complex chips is difficult.   This talk presents […]

ESE Fall Seminar – “Acceleration by Stepsize Hedging”

Glandt Forum, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

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 – “Quantum sensing and imaging with diamond spins”

Berger Auditorium (Room 13), Skirkanich Hall 210 South 33rd Street, Philadelphia, PA, United States

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 – “Approximate symmetries in machine learning”

Glandt Forum, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

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 […]
