But I argued that it would be more helpful to students’ understanding of the derivative to start with a simpler case first, namely to use only piecewise-linear functions at the beginning.

This article is concerned with the computational aspect of l₁ regularization problems with a certain class of piecewise linear loss functions. The problem of computing the l₁ regularization path for a ...

These functions may be called piecewise-linear. Smooth functions that are related to the hyperbola and that have piecewise-linear functions as limiting forms are particularly useful for response ...

We investigate hedging strategies using piecewise linear risk minimization. We illustrate that this criterion for risk minimization may lead to a smaller expected total hedging cost and significantly ...
