Solved: Hi, I work on a project that needs a nonlinear least squares solver. So far I worked in Matlab, but the final code needs to run in C/C++ (but
最小二乘法是一种数学优化技术，它通过最小化误差的平方和找到一组数据的最佳函数匹配。最小二乘法是用最简的方法求得一些绝对不可知的真值，而令误差平方之和为最小。最小二乘法通常用于曲线拟合。很多其他的优化问题也可通过最小化能量或最大化熵用最小二乘形式表达。比如从最简单的一次函数y=kx...
The Matlab back- slash operator computes a least squares solution to such a system. beta = X\y The basis functions might also involve some nonlinear parameters, α1, . . . , αp. The problem is separable if it involves both linear and nonlinear parameters: y(t) ≈β1ϕ1(t, α) ...
1. Least-squares(最小二乘法)是最经典的机器学习算法,后续的大部分机器学习算法(包括题主提到的Lasso,ridge regression)都是在其基础上发展而来的。Linear model即 ,只要求得其参数 ,便可以得到自变量 与因变量 的映射关系。因此有监督回归的任务就是通过 ...
