Web6 jan. 2024 · 梯度下降法是一种常用的机器学习算法，主要用于求解优化问题。它的基本原理是迭代地调整参数，使得目标函数的值最小化。我们设目标函数为 $J (\theta)$，其中 $\theta$ 是参数，调整参数的过程就是不断地更新 $\theta$ 的值，使得 $J (\theta)$ 最小化。具体来说，在每次迭代中，都会计算出 $\theta$ 对 $J (\theta)$ 的梯度，然后沿着梯度 … Webpermutation = list (np.random.permutation (m)) #它会返回一个长度为m的随机数组，且里面的数是0到m-1 shuffled_X = X [:,permutation] #将每一列的数据按permutation的顺 …
