梯度下降法(gradient descent)或最速下降法(steepest descent)是求解无约束优化问题的一种最常用的方法,实现简单,属于一阶优化算法,也是迭代算法。 1.梯度 在微积分中,对多元函数的参数求偏导数,把求得的各个参数的偏导数以向量的形式写出来,就是梯度。比如函数f(x,y)f(x,y),分别对x,yx,y求...
The code highlights the Gradient Descent method. The algorithm works with any quadratic function (Degree 2) with two variables (X and Y). Refer comments for all the important steps in the code to understand the method. In order to implement the algorithm for higher order polynomial eq...

matlab实现梯度下降法(Gradient Descent)的一个例子 在此记录使用matlab作梯度下降法(GD)求函数极值的一个例子: 问题设定: 1. 我们有一个nn个数据点,每个数据点是一个dd维的向量,向量组成一个data矩阵X∈Rn×dX∈Rn×d,这是我们的输入特征矩阵。 2. 我们有一个响应的响应向量y∈Rny∈Rn。
I have tried to implement the gradient descent method to optimize the parameter of a system but it not identifying the true parameter 'g'. I think my implememtation is not up to the mark. Here is my code clc; clearall; closeall; ...
Rosenbrock函数Matlab代码局部最小化器的梯度最速下降法 该项目演示了如何找到该算法在任何维度(1、5、10、100、200、300)的函数的局部极小值。 代码实现 代码在 Matlab R2018b 中实现。 描述 此代码演示了 [-2,2] 区间的 5 维 Rosenbrock 函数的局部最小化。 此外,代码可用于任何维度的任何功能。 必须考虑...
