WebMay 30, 2014 · Autoencoder - By training a neural network to produce an output that’s identical to the input, but having fewer nodes in the hidden layer than in the input, you’ve built a tool for compressing the data. Going from the input to the hidden layer is the compression step. You take, e.g., a 100 element vector and compress it to a 50 element vector. citizenship bank
