The main objective of this paper is to provide a state-of-the-art survey of advanced optimization methods used in machine learning. It starts with a short introduction to machine learning followed by the formulation of optimization problems in three main approaches to machine learning. Then ...
when havea largemachine learning problem,一般会使用这些advanced optimization algorithm而不是gradient descent Conjugate gradient, BFGS,L-BFGS很复杂,可以在不明白详细原理的情况下进行应用(使用software libary)。 可以使用Octave和matlab的函数库直接进行应用,这些软件里面的build-in libarary已经很好的实现了这些算法。
