Bptt backpropagation through time
WebBPTT, or backpropagation through time, is a neural network training algorithm that is used to train recurrent neural networks. The algorithm is designed to propagate errors … Backpropagation through time (BPTT) is a gradient-based technique for training certain types of recurrent neural networks. It can be used to train Elman networks. The algorithm was independently derived by numerous researchers.
