Title:

Deterministic Learning for Compressed Classification

Speaker:

Prof Kar-Ann Toh, School of EEE, Yonsei University, South Korea

 

Abstract:

Pattern classification with compact representation is an important component in machine learning. In this work, an analytic bridge solution is proposed for compressive classification. The proposal has been based upon solving a penalized error formulation utilizing an approximated Lp-norm. The solution comes in a primal form for over-determined systems and in a dual form for under-determined systems. While the primal form is suitable for problems of low dimension with large data samples, the dual form is suitable for problems of high dimension but with a small number of data samples. The solution has also been extended for problems with multiple classification outputs. Numerical studies based on simulated and real-world data validated the effectiveness of the proposed solution.
