Proximal backpropagation

WebbBackpropagation, short for backward propagation of errors, is a widely used method for calculating derivatives inside deep feedforward neural networks. Backpropagation … WebbPython Neural Network ⭐ 278. This is an efficient implementation of a fully connected neural network in NumPy. The network can be trained by a variety of learning algorithms: backpropagation, resilient backpropagation and scaled conjugate gradient learning. The network has been developed with PYPY in mind. total releases 4 most recent commit ...
