Support Vector Machines

Support Vector Machines. Instructor Max Welling ICS273A UCIrvine. Philosophy. First formulate a classification problem as finding a separating hyper-plane that maximizes “the margin”. Allow for errors in classification using “slack-variables”. Convert problem to the “dual problem”.
