support vector machines � learning machines

classification, regression, novelty detection etc.

can derive a NN, RBF net, polynomial classifier from them

it�s general in the problems you can tackle

SVMs

fewer choices to be made

convex curve, as opp to back propagation net where there are sub-optimal solutions

kernel

kernel parameter

statistical learning theory � simplest task is binary classification, separating hyperplane is maximally distant from the two clusters

utilise support vectors to help separate out the two clusters
