[Colloquium] REMINDER: 6/2 Research at TTIC: Suriya Gunasekar, TTIC

[Mary Marre via Colloquium]

When:     Friday, June 2nd at noon



Where:    TTIC, 6045 S Kenwood Avenue, 5th Floor, Room 526



Who:       Suriya Gunasekar, TTIC


*Title:*       Implicit Regularization in Matrix Factorization

*Abstract:* This talk will explore ideas on "implicit regularization" in
underdetermined problems where the optimization objective has multiple
global minima. We specifically study optimization of a quadratic loss over
a matrix with gradient descent on the factorized space. We conjecture and
provide empirical and theoretical evidence that with small enough step
sizes and initialization close enough to the origin, gradient descent on a
full dimensional factorization converges to the minimum nuclear norm
solution.

*Research at TTIC Seminar Series*

TTIC is hosting a weekly seminar series presenting the research currently
underway at the Institute. Every week a different TTIC faculty member will
present their research.  The lectures are intended both for students
seeking research topics and adviser, and for the general TTIC and
University of Chicago communities interested in hearing what their
colleagues are up to.

To receive announcements about the seminar series, please subscribe to the
