… Input image Compute similarities with training images “Machine leanring mumbo jumbo” I think in general, you’d just think to use nearest neighbors … Compute similarities with training images Some kind of classifier

K is not... Positive definite A metric A function on Rn x Rn Differentiable

Algorithm: When K is pd, use an SVM

Generalization when K is pd Analyze the generalization of a class of linear separators.

Algorithm: When K is not pd

Algorithm: With prototype Selection
