Today’s “AI”-derived engineer-level models of the neural mechanisms of primate object perception, and tests of their application in non-invasive modulation of high level brain states

Vision and AI
James DiCarlo
MIT

The human species is on a great scientific quest — to understand the neural mechanisms of human (primate) intelligence.  Recent progress in multiple subfields of brain research suggests that ke

Are black holes real – a mathematical perspective

Special Guest Seminar
Sergiu Klainerman
Princeton

Given that black holes are by definition not directly observable, physicists had to devise indirect techniques to test their reality. These efforts were recognized by 6 Nobel prizes in 2017 and 2020.

Coding Theory in Almost-Linear Time and Sub-Linear Space

Foundations of Computer Science Seminar
Dana Moshkovitz
UT Austin

Typical time-efficient encoding and decoding algorithms for error correcting codes use linear space. We construct asymptotically good codes that can be deterministically encoded in almost linear time

Density of growth-rates of subgroups of a free group

Midrasha on Groups Seminar
Gal Yehuda
Yale

We prove the set of growth-rates of subgroups of a rank~r free group is dense in [1,2r−1]. Our main technical contribution is a concentration result for the leading eigenvalue of the non-backtrackin

The seminar will be frontal and also on Zoom (password: 400359)

Cosystolic expanders

Midrasha on Groups Seminar
Shai Evra
HUJI

In this talk we will introduce a notion slightly weaker than the coboundary expansion notion of Linial–Meshulam called the cosystolic expansion,  which is strong enough to implies Gromov’s to

Making SGD as Parameter-Free as Possible

Machine Learning and Statistics Seminar
Yair Carmon
TAU

While stochastic optimization methods drive continual improvements in machine learning, choosing the optimization parameters—particularly the learning rate (LR)—remains challenging. In this talk,

Expander with respect to random regular graphs

Geometric Functional Analysis and Probability Seminar
Manor Mendel
OpenU

Expander is a family of constant degree graphs with spectral gaps larger than some positive constant. From a Metric Geometry perspective, the spectral gap implies their non-embeddability in Hilbert sp

Incompressibility and Next-Block Pseudoentropy

Foundations of Computer Science Seminar
Noam Mazor
Cornell Tech

A distribution is k-incompressible, Yao [FOCS ’82], if no efficient compression scheme compresses it to less than k bits. While being a natural measure, its relation to other computational analogs o

Recovering the Pre-Fine-Tuning Weights of Generative Models

Vision and AI
Eliahu Horwitz
HUJI

The dominant paradigm in generative modeling consists of two steps: i) pre-training on a large-scale but unsafe dataset, ii) aligning the pre-trained model with human values via fine-tuning. This prac
