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 ...

Abstract: It is well-known that solutions to parametric linear or quadratic programs are continuous piecewise affine functions of the parameter. In this paper we prove the converse, i.e. that every ...

Abstract: In this paper, an algorithm for solving piecewise-linear networks that include elements with discontinuous characteristics is presented. The algorithm is based on modifications of the ...

In this paper, we propose a method for finding the best piecewise linearization of nonlinear functions. For this aim, we try to obtain the best approximation of a nonlinear function as a piecewise ...

In this paper, in order to solve signal instability of high-performance liquid chromatography-diode array detection (HPLC-DAD) data and maintain the second-order advantage, this work proposed ...

A React app for converting an f(x) function into a piecewise function. Especially useful if you have a function f(x) that cannot be solved for x. This repo is hosted on Netlify and any changes/commits ...
