多元线性回归解析解

数学推导基本概念在整个线性回归的学习中，求得一组最优的权重是我们的目的。权重W是一维向量，记作W=[w1 w2 .... wn].一般的，权重为n行的列向量。特征X是一维向量，记作X=[x1 x2 x3 .....xn]，一般的，特征为n行的列向量。在二维空间中，我们有y = ax+b,现在，我们将其拓展到n维空间，则有y = w0 + w1x1...

PyTorch实例：简单线性回归的训练和反向传播解析

引言在神经网络中，反向传播算法是一个关键的概念，它在训练神经网络中起着至关重要的作用。本文将深入探讨反向传播算法的原理、实现以及在深度学习中的应用。什么是反向传播？反向传播（Backpropagation）是一种用于训练神经网络的监督学习算法。它的基本思想是通过不断调整神经网络中的权重和偏差，使其能够逐渐适应输入数据的特征，从而实现...
