Canonical piecewise-linear approximations
Ji-Nan Lin, Rolf Unbehauen · IEEE Transactions on Circuits and Systems I Fundamental Theory and Applications · 1992
The canonical representation of piecewise-linear functions is considered as a universal approximation scheme of multivariate functions. Meanwhile, two universal approximation schemes in terms of combinations of univariate canonical piecewise-linear functions are proposed. The discussion supports the application of these schemes in mapping networks, e.g. neural networks or adaptive nonlinear filters.>
