Learning from Data: Optimization and Low-Rank Factorization

Friday, June 14, 12-1 p.m.

EN-4000

Lunch and learn session.

Abstract

Inspecting data to uncover valuable information is critical, especially with the increasing data from advancing technologies. Low-rank factorization techniques, such as nonnegative matrix factorization (NMF), exploit matrix structures to handle missing values, detect anomalies and reduce dimensionality for knowledge extraction. This talk will cover NMF, its optimization methods and practical applications in revealing latent information from nonnegative data.
