Kernelized perceptron
WebBy contrast with the linear models learned by the perceptron, a kernel method is a classifier that stores a subset of its training examples x i, associates with each a weight α i, and … Weblearning rules, including the Perceptron rule, can be seen as implementing a stochastic gradi-ent step. Many such methods, including the Perceptron and the Passive Aggressive method [11] also have strong connections to the “margin” or norm of t he predictor, though they do not directly minimize the SVM objective.
