Signal Approximations Based on Nonlinear and Optimal Piecewise Affine Functions

In this work, we address the problem of piecewise affine approximations, that is, to find piecewise affine functions that well-approximate a given signal. The proposed approach is optimal in the sense of L 2 norm and formulated in a compact and explicit way; no fitting stage is needed. Also, affine...
