Backpropagation algorithm python
The Pennsylvania State University
The ANN used here is a feed-forward neural network trained by a backpropagation algorithm (Reed 1998), which is commonly referred to as a . multi-layer perceptron (Rosenblatt 1958). The specific neural network module used in this study is the newff model in the Neurolab python library (https: ...
