Machine learning models are vulnerable to adversarial examples: small changes to images can cause computer vision models to make mistakes such as identifying a school bus as an ostrich. However, it is still an open question whether humans are prone to similar mistakes. Here, we address this question by leveraging recent techniques that transfer adversarial examples from computer vision models... More >

The extracellular matrix (ECM) is a complex assembly of structural proteins that provides physical support and biochemical signaling to cells in tissues. Over the last two decades, studies have revealed the important role that ECM elasticity plays in regulating a variety of biological processes in cells, including stem cell differentiation and cancer progression. However, tissues and ECM are... More >

Colloquium | November 7 | 12:10-1:15 p.m. | 1104 Berkeley Way West
Mina Cikara, Assistant Professor, Harvard University
If humans are innately good, cooperative, fair, and averse to harming one another, why does widespread intergroup conflict persist? Several factors contribute to fomenting hostility between groups; in my talk I will focus on the role of pleasure in response to out-group pain. People who identify strongly with their social groups frequently experience pleasure when they observe threatening... More >
Colloquium | November 7 | 12:30-2 p.m. | 223 Moses Hall
Professor Jason Corburn will describe a ten-year partnership between his UC Berkeley team and the NGO Shack/Slum Dwellers International (SDI) focused on improving the lives and living conditions in the urban slums of East African Cities.
Seminar | November 7 | 2-3 p.m. | 736 Evans Hall
Nate Bottman, Princeton University
In my first talk, I will introduce the Fukaya category of a compact symplectic manifold. This is an invariant that keeps track of the Lagrangian submanifolds, as well as an intersection theory of these submanifolds that is enhanced by counts of pseudoholomorphic polygons. The algebraic structure of the Fukaya category is controlled by a collection (in fact, an operad) of polytopes called... More >
Seminar | November 7 | 3-4 p.m. | 1011 Evans Hall
Amir Dembo, Stanford University
We consider a family of random growth models in n-dimensional space. These models capture certain features expected to manifest at the mesoscopic level for certain self-interacting microscopic dynamics (such as once-reinforced random walk with strong reinforcement and origin-excited random walk). In a joint work with Pablo Groisman, Ruojun Huang and Vladas Sidoravicius, we establish for such... More >
Representation Theory and Mathematical Physics Seminar: Premodular categories and 4-dimensional topological field theories
Seminar | November 7 | 4-5 p.m. | 891 Evans Hall
Alexander Kirillov Jr., Stony Brook University
The notion of topological field theory was formalized by Michael Atiyah; it is a purely mathematical notion inspired by physics. In particular, such a theory gives invariants of closed \(d\)-manifolds.
Examples of 3-dimensional topological field theories have been well studied, most notably Reshetikhin–Turaev and Turaev–Viro theories. However, in dimension 4, situation is much less... More >
ERG Colloquium: Itay Fischhendler: The Political Economy of Shifting Renewable Energy Targets: A Global Perspective

Seminar | November 7 | 4-5 p.m. | 3 Evans Hall
Nate Bottman, Princeton University
In my second talk, I will describe a framework for building maps between Fukaya categories of different symplectic manifolds. This is a 2-category-like structure called Symp, where the objects are symplectic manifolds, the 1-morphisms are Lagrangians in products, and the 2-morphisms are intersections of these Lagrangians. Just as the structure of the Fukaya category comes from an operad of... More >
Why Deep Learning Works: Traditional and Heavy-Tailed Implicit Self-Regularization in Deep Neural Networks
Seminar | November 7 | 4-5 p.m. | 1011 Evans Hall
Michael W. Mahoney, UC Berkeley
Random Matrix Theory (RMT) is applied to analyze the weight matrices of Deep Neural Networks (DNNs), including both production quality, pre-trained models and smaller models trained from scratch. Empirical and theoretical results clearly indicate that the DNN training process itself implicitly implements a form of self-regularization, implicitly sculpting a more regularized energy or penalty...

Professor Michael Silver Psychology Colloquium Lecture: Effects of acetylcholine on visual cortex, attention, and learning
Colloquium | November 7 | 5:15-6:15 p.m. | 1104 Berkeley Way West
The neurotransmitter acetylcholine (ACh) has been extensively studied at the level of synapses and neural circuits, but comparatively little is known about its effects on perception and cognition in humans. We augmented the effects of ACh in the brains of healthy human participants by administering the cholinesterase inhibitor donepezil (trade name: Aricept). I will describe the effects of... More >
