斯坦福大学《Machine Learning》第五周学习过程中,对反向传播算法的几个公式看得云里雾里的,这里做一个详细的推导和总结 公式一: 公式二: 公式三: 首先已知,这个是我们定义的,不用推导,但是为什么要这样定义呢? 我们给神经元的加权输入添加一点改变,这就导致了神经元的输出变成了,而不是之前的。这个改变在后续的...

[Machine Learning] Backpropagation Algorithm "Backpropagation" is neural-network terminology for minimizing our cost function, just like what we were doing with gradient descent in logistic and linear regression. Our goal is to compute: 分类:Machine Learning...
What is a backpropagation algorithm in machine learning? Backpropagation is a type ofsupervised learningsince it requires a known, desired output for each input value to calculate the loss function gradient, which is how desired output values differ from actual output. Supervised learning, the most...
