Former head of Baidu AI Group/Google Brain. It seems likely also that the concepts and techniques being explored by researchers in machine learning may. In this amazing. For some reason, I felt called to take it, so I did. Training with Backpropagation 24 That's almost backpropagation It's simply taking derivatives and using the chain rule! Remaining trick: we can re-use derivatives computed for higher layers in computing derivatives for lower layers! Example: last derivatives of model, the word vectors in x.
