[Algorithm] The_Levenberg-Marquardt_Algorithm DL : 0: LM算法老外写的The Levenberg-Marquardt (LM) algorithm is the most widely used optimization algorithm. It outperforms simple gradient descent and other conjugate gradient methods in a wide variety of problems. This document aims to provide an intuitive explanation for this algorithm. The LM algorithm is ﬁ rst shown to be a blend of vanilla gradient descent and Gauss-Newton iteration. Subsequently, another perspective on the algorithm is provided by considering it as a trust-region method-The Levenberg-Marquardt (LM) algorithm is the most widely used optimization algorithm.
