Dissertation Talk: Efficient Robot Learning of Robust Grasping Policies from Synthetic Training Datasets
Presentation | May 7 | 9-10 a.m. | 310 Soda Hall
Rapid and reliable robot grasping of a wide variety of objects remains a Grand Challenge for robotics due to sensor noise, imprecise control, and partial observability. Deep neural networks trained on datasets of human-labeled or self-supervised grasps can be used to rapidly plan grasps across a diverse set of objects, but data collection is tedious and performance may asymptote with training...

The Oliver E. Williamson Seminar on Institutional Analysis, named after our esteemed colleague who founded the seminar, features current research by faculty, from UCB and elsewhere, and by advanced doctoral students. The research investigates governance, and its links with economic and political forces. Markets, hierarchies, hybrids, and the supporting institutions of law and politics all come... More >

Title: The Secret Lives of Retinal Astrocytes
Abstract: The study of glia the support cells of the central nervous system has come a long way since Rudolf Virchow described a connective tissue of the brain that he termed nervenkitt in 1856. Rather than a passive scaffolding for neurons (the word glia means glue in Greek), these cells are responsible for a... More >

We give obstructions to and constructions of Lagrangian cobordisms between configurations of Lagrangian torus fibres in a symplectic manifold which is the total space of an integrable system. The results are proven using family Floer theory and tropical geometry, and are motivated by a relationship to rational equivalence of zero-cycles on a mirror rigid analytic space. This talk reports on joint... More >

We consider the adversarial multi-armed bandit problem with partial feedback, minimizing a non-negative loss function using the graph based feedback framework introduced by Mannor and Shamir in 2011. We offer algorithms that attain small loss bounds, as well as low approximate regret against a shifting comparator.
Classical learning algorithms add a low level of uniform noise to the... More >

Northern California Symplectic Geometry Seminar: Mirror Symmetry for symplectic toric Calabi-Yau 3-folds
Seminar | May 7 | 4-5 p.m. | Stanford University, Room 383N
Chiu-Chu Melissa Liu, Columbia
We will describe several versions of mirror symmetry for symplectic toric Calabi-Yau 3-folds, with three different mirror complex geometries: the Landau-Ginzburg mirror, the Hori-Vafa mirror Calabi-Yau 3-fold, and the mirror curve. This is partly based on joint work with Bohan Fang and Zhengyu Zong.
