NOTES

A Sparse Representation For Function Approximation

Tomaso Poggio and Federico Girosi

We derive a new general representation for a function as a linear combination of local correlation kernels at optimal sparse locations (and scales) and characterize its relation to principal component analysis, regularization, sparsity principles, and support vector machines.
