Talk Title: NeuroAIAbstract: NeuroAI creates synergies between the study of brains and AI based on neural architectures with massively parallel processing units highly connected by weights and trained by learning algorithms. ChatGPT was an overnight success that took 40 years to achieve. Insights from AI may help us better understand cognitive processing in brains.Bio: Sejnowski is the Francis Crick Chair at the Salk Institute and a Distinguished Professor of Neurobiology at UC San Diego. He is a leader in NeuroAI, the recent convergence between neuroscience and AI. He is a member of the National Academies of Sciences, Engineering, Medicine, and Inventors. He was awarded the Brain Prize in 2024 and was elected a Fellow the Royal Society in 2025.https://www.hhmi.org/scientists/terrence-j-sejnowskiFollowed by a reception with food and drink in 3rd floor atrium

Speaker: Tom Bohman (Carnegie Mellon University)Title: Two point concentration of the domination number of the random graphAbstract:We show that the domination number of the binomial random graph G_{n,p} with edge probability p =n^{-\gamma} is concentrated on two values for \gamma < 2/3 and not concentrated on two values for \gamma > 2/3.The main ingredient in the proof is a Poisson type approximation for the probability that a random bipartite graph has no isolated vertices in a regime where standard tools are not available.Joint work with Lutz Warnke and Emily Zhu.

Speaker: Sourav Chatterjee (Stanford)Title: Neural networks can learn any low complexity patternAbstract:Neural networks have taken over the world, but research on why they work so well is still in its infancy. I will present a baby step in this direction, based on joint work with my student Tim Sudijono. We show, with quantitative bounds, that a certain kind of neural network can quickly learn any pattern that can be expressed as a short program. An example is as follows. Let N be a large number, and suppose we have data consisting of a sample of X’s and Y’s, where each X is a randomly chosen number between 1 and N, and the corresponding Y is 1 if X is a prime and 0 if not. The sample size n is negligible compared to N. If we fit a neural network to this data which is “sparsest” in a suitable sense, it turns out that the network will be able to accurately predict if a newly chosen X is a prime or not, with a sample of size as small as (log N)^2 — even though the network does not know, a priori, that we are asking it to detect primality. The talk will be accessible to those with no background in neural networks; I will define all necessary concepts.*Pre-reception held in 2-290 at 4pm.

Speaker: Jane Shi (MIT)Title: Katz's proof of the Riemann hypothesis for curvesAbstract:Reference: Katz, A Note on Riemann Hypothesis for Curves and Hypersurfaces Over Finite Fields, Sections 1-4.

Speaker: Chi Hong Chow (Virginia Tech)Title: Mirror symmetry and Gamma conjectures for flag varietiesAbstract: Mirror symmetry predicts that the quantum 𝐷-module of a Fano manifold should be isomorphic to the Gauss-Manin system of its mirror Landau-Ginzburg model. Furthermore, the Betti integral structure on the latter should correspond to an explicit integral structure on the former involving the Gamma class. Closely related is Gamma conjecture I proposed by Galkin, Golyshev and Iritani. In this talk, I will discuss this story in the context of flag varieties.

This talk traces the political power of motherhood and childrearing in Arabic thought between 1850 and 1939. It shows how writers used ideas about childrearing (tarbiya in Arabic) to address key issues in modern social thought, such as freedom, labor, and democracy. While debates about childrearing in Arabic led to expansions in girls' education and women writers' authority, they also attached the fate of nations to women's unwaged labor in the home. Highlighting Arab women's writing offers a new way to think about the devaluation of social reproduction under capitalism, the stubborn maleness of the liberal subject, and why the idea of embodied, binary gender difference has proven so difficult to overcome.

Vincent Anioke, ’17, returns to MIT to read from his book of short stories, Perfect Little Angels, published to acclaim last year by Arsenal Pulp Press.Set in both Nigeria and Canada, these stunning stories have been praised for their candor, tenderness, and deep humanity, and described as “brilliant and harrowing.” Through masterful writing, Anioke evokes complex and unforgettable characters who “grapple with the harsh consequences of unforgiving traditions and defiant desires”.Anioke was born and raised in Nigeria, now lives in Canada, and works as a software engineer at Google. His short stories have appeared in SmokeLong Quarterly, Masters Review, Split Lip Magazine, Carve, and Pithead Chapel. He was the 2021 Austin Clarke Fiction Prize Winner and was shortlisted for the 2021 Commonwealth Short Story Prize.At MIT, Anioke was an Admissions blogger and Course 6 major. He won numerous writing prizes, including CMS/W’s Robert A. Boit Prize for short stories, Boit Manuscript Prizes for essays and fiction, the King Prize for Science Fiction Writing, and the Louis Kampf Writing Prize in Women’s & Gender Studies.
