May 28, 2020 · Hi everyone! I am deploying a sparse autoencoder. Briefly, an autoencoder is a feedforward NN that is formed by a series of layers of decreasing dimension (the encoder), followed by a series of layers of increasing dimension (the decoder). The loss is computed by the MSE between NN’s input and decoder’s output. At the end of the encoder, instead, there is the encoded input. I want to limit ...
