Title:  Greedy primal algorithms for building sparse SVMs

Abstract:

Sparsity (using a small number of basis functions) is important in
applications requiring great classification speed. This talk will review
existing methods for building sparse SVMs, point out their drawbacks,
and discuss an effective new primal greedy method which is along the
lines of matching pursuit algorithms in least squares. The method is
also very efficient: it greedily chooses a set of d kernel basis  
functions
to approximate the SVM primal cost function well in O(n d^2) time, where
n is the number of training examples.

***The talk will be followed by refreshments in Ryerson 255***
