MEAM Seminar: “Dynamical Systems Approach to Geophysical and Aerospace Flows”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

A dynamical systems approach is taken to explain the dynamics of two classes of ‘gap-leaping’ geophysical flow as well as the hypersonic second-mode instability. First, in the context of a […]

CBE Seminar: “Complexity in the Chemistry and Physics of Lipid Membranes as a Handle to Activate the Delivery of Cargo to Cells”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Abstract: Lipid materials having nanostructures that deviate from the conventional flat bilayer arrangement such as hexagonally packed lipid tubes and bi-continuous cubic phases are ubiquitous in nature. Their role remains elusive but over […]

PRiML Seminar: “Building Algorithms by Playing Games”

Room 401B, 3401 Walnut 3401 Walnut Street, Philadelphia, PA, United States

A very popular trick for solving certain types of optimization problems is this: write your objective as the solution of a two-player zero-sum game, endow both players with an appropriate learning […]

ESE & Statistics Seminar: “Large Neural Networks: Insights from Linearized Models”

PICS Conference Room 534 - A Wing , 5th Floor 3401 Walnut Street, Philadelphia, PA, United States

Abstract: Modern machine learning models, and in particular multilayer neural networks, exhibit a broad range of puzzling phenomena. Their training requires to minimize a highly non-convex high-dimensional cost function, and […]

CIS Seminar: “What Society Must Require from AI”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Abstract:  Artificial intelligence (AI) algorithms, especially machine learning (ML) programs, are now being employed or proposed for use in: a) scanning résumés to weed out job applicants; b) evaluating risks […]
