The Berkeley Campus is Open

Visit the UC Berkeley COVID-19 resources website for the latest testing and access information.  Cory and Soda Halls are open but we will likely have limited in-person/on-site staffing during the first two weeks of the Spring 2022 semester.  Although most classes will be conducted remotely during this time, we anticipate in-person instruction to resume on January 31st.

Dissertation Talk: Learning to generalize in dynamic environments: Fully test-time adaptation by online and offline optimization

Zoom
  • Dequan Wang, UC Berkeley
A model must adapt itself to generalize to new and different data during testing. In this setting of fully test-time adaptation the model has only the test data and its own parameters. We propose to adapt by test entropy minimization (tent): we optimize the model for confidence as measured by the entropy of its predictions. Tent reduces generalization error for image classification on corrupted...

Ultracoherent Nanomechanical Oscillators for Quantum Optomechanics: Joint CIQC / Nano Seminar

180 Tan Hall
  • Prof. Tobias J. Kippenberg, EPFL Lausanne / Physics & EE
The reduction of mechanical dissipation increases force sensitivity of mechanical oscillators and decreases the thermal decoherence rate of mechanical quantum states. Concomitantly, reduced size allows stronger coupling to other degrees of freedom such as electromagnetic fields. These two demands are conflicting: due to surface losses, smaller size typically leads to increased dissipation....

Heavy Element Biological Coordination: A Fundamental Take on the Intersection of Waste Management, Decontamination and Nuclear Medicine: Nano Seminar series

180 Tan Hall
  • Prof. Rebecca Abergel, UC Berkeley, Nuclear Engineering
From potential contamination of individuals with radioactive fission products after a nuclear accident to the therapeutic use of radio-isotopes for cancer diagnostics and treatment, the coordination and biological chemistry of actinides have become increasingly relevant to a number of applied problems. Understanding the fundamental bonding interactions of selective metal assemblies presents a...

Algorithm-Driven Paradigms for Freeform Photonic Metamaterials: Nano Seminar series

180 Tan Hall
  • Prof. Jonathan Fan, Stanford University, Electrical Engineering
In this talk, I will discuss advances in photonic engineering in which algorithmic approaches to device implementation unlock new functional capabilities for wavefront engineering. In the first part, I will discuss the utilization of freeform optimization for metamaterials in which non-local, multiple scattering dynamics enable new regimes of device efficiency and multi-functionality. These...

Continuous Liquid Interface Production (CLIP): 3D Printing at the Intersection of Materials, Process and Design: Nano Seminar series

180 Tan Hall
  • Prof. Joseph M. DeSimone, Stanford University, ChemE & MSE & Business
The production of polymer products relies largely on age-old molding techniques. A major reason for this is that additive methods have not delivered meaningful alternatives to traditional processes—until now. In this talk, I will describe Continuous Liquid Interface Production (CLIP) technology, which embodies a convergence of advances in software, hardware, and materials to bring the digital...
