八度中fminunc的Java实现 [英] Java implementation of fminunc in octave

问题描述

我试图在Java中找到八度的fminunc(函数最小化不受限制)库的Java版本.目的是将其用于逻辑回归.

I am trying to find a java version of octave's fminunc (function minimization unconstrained) library in Java. The goal is to use it for logistic regression.

当前，我正在使用梯度下降的自制版本以使成本最小化，并且我希望能够使用一个已经存在的库(在Java中)为我做到这一点.这与我从 Coursera机器学习 Java课程.

Currently, I am using a home-brewed version of gradiant descent for cost minimization and I would like to be able to use an already existing library to do that (in Java) for me. This is related to my effort of porting octave code that we have from the Coursera Machine Learning course to Java.
