Fall 2023 Seminar Series

Department of Statistics and Data Science 2023-2024 Seminar Series - Fall 2023

The 2023-2024 Seminar Series will primarily be in person, but some talks will be offered virtually using Zoom. Talks that are virtual will be clearly designated and registration for the Zoom talks will be required to receive the zoom link for the event. Please email Kisa Kowal at k-kowal@northwestern.edu if you have questions. 

Seminar Series talks are free and open to faculty, graduate students, and advanced undergraduate students

Statistical Optimality and Computational Tractability of ICA

Friday, September 29, 2023

Time: 2:00 p.m. to 3:00 p.m. central time

Location: Ruan Conference Room – lower level (Chambers Hall 600 Foster Street)

Speaker: Ming Yuan, Professor, Department of Statistics and Associate Director, Data Science Institute, Columbia University

Abstract: Independent component analysis (ICA) is a powerful and general data analysis tool. Yet there is an increasing amount of empirical evidence that the classical methods for ICA are not well suited for modern applications, both computationally and statistically, where the effect of dimensionality is not negligible. We will investigate the optimal sample complexity and statistical performance for ICA, and how considerations of computational tractability may affect them. We will also introduce estimating procedures for ICA that are both statistically efficient and computationally tractable. Our development exploits the close connection between ICA and moment estimation and reveals a number of new insights for both problems.

This talk will be given in person on Northwestern's Evanston campus at the location listed above.
