We can construct a "kernel perceptron" by taking the standard perceptron and replacing the inner product X ⊺ X = X, X with the equivalent (due to the "kernel-trick") form K (X,X). This works since we have that the inner product is a map < ⋅, ⋅ >: R p × R p → R, which has identical properties to the kernel function k: R p × R ...
