Forward propagation algorithm
WebOct 16, 2024 · The network in the above figure is a simple multi-layer feed-forward network or backpropagation network. It contains three layers, the input layer with two neurons x 1 and x 2, the hidden layer with two neurons z 1 and z 2 and the output layer with one neuron y in. Now let’s write down the weights and bias vectors for each neuron. WebDec 7, 2024 · Implementation of forward-forward (FF) training algorithm - an alternative to back-propagation Below is my understanding of the FF algorithm presented at Geoffrey Hinton's talk at NeurIPS 2024. The conventional backprop computes the gradients by successive applications of the chain rule, from the objective function to the parameters.
