A privileged subset, known as exactly solvable models, possess algebraic structure that allows for exact formulas for their probability distributions.\n\nFor an even smaller subset of these models, their distributions have been shown to satisfy nonlinear equations from classical integrable systems, including Painlev\u00e9, KP, and Toda equations. Why should equations from soliton theory appear in random growth, and why do they keep reappearing across different models?\n\nI will describe a framework that gives a common algebraic explanation and extends this connection to eighteen exactly solvable models. The framework organizes the Fredholm determinant formulas of solvable KPZ models into an overdetermined linear problem whose compatibility conditions reveal a discrete integrable structure gauge equivalent to the non-abelian Hirota\u2013Miwa equation.", "occurrence_notes":null, "guid":"151181-21911040@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/151181", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"4088", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"", "sponsors":[ { "group_name":"Probability and Analysis Seminar - Department of Mathematics", "group_id":"5203", "website":"https:\/\/sites.google.com\/view\/probsemumich\/future-talks" }, { "group_name":"Department of Mathematics", "group_id":"3791", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21911040 } , "152003-21913946": { "datetime_modified":"20261001T182153", "datetime_start":"20261007T160000", "datetime_end":"20261007T170000", "has_end_time":1, "date_start":"2026-10-07", "date_end":"2026-10-07", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"Program in Biology & Undergraduate Program in Neuroscience Events 2026 - 2027", "occurrence_title":"Pizza with Professors - Neuroscience", "combined_title":"Program in Biology & Undergraduate Program in Neuroscience Events 2026 - 2027: Pizza with Professors - Neuroscience", "event_subtitle":"", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Events in this track are open to all current and prospective PiB and UPiN students.

In unconstrained problems with exact gradients, momentum-based methods\u2014most notably Nesterov\u2019s accelerated gradient descent (AGD) and Polyak\u2019s heavy-ball (HB) method\u2014achieve faster convergence by improving dependence on the condition number. However, this acceleration comes at a cost: momentum amplifies gradient noise, making these methods less robust than GD under standard parameter choices and requiring more accurate gradient estimates to attain comparable accuracy. Similar challenges arise in convex and nonconvex min\u2013max optimization.\nMotivated by applications in machine learning, this talk studies unconstrained and min\u2013max optimization under deterministic, unbiased stochastic, and biased stochastic gradient noise. I will present new algorithms that achieve optimal robustness against different noise types, using control-theoretic tools such as the H_2\u200b norm, the H_\u221e\u200b norm, and the risk-sensitivity index, together with coherent risk measures. I will also discuss worst-case noise constructions and high-probability convergence guarantees. This perspective builds a bridge between optimization and robust control theory and enables the design of noise-robust and risk-sensitive accelerated methods.\nRepresentative Publications:\nM.
