If the input to an autoencoder is a vector , then the encoder maps the vector x to another vector as follows:
where the superscript (1) indicates the first layer. is a transfer function for the encoder, is a weight matrix, and is a bias vector. Then, the decoder maps the encoded representation z back into an estimate of the original input vector, x, as follows:
where the superscript (2) represents the second layer. is the transfer function for the decoder, is a weight matrix, and is a bias vector.
