Matrix Factorization using Auto-Encoder

The following figure shows how auto-encoder wroks:

Codes & Results

The code consist of two parts. One is for the data preprocessing, and one implements and matrix factorization using auto-encoder, and gets the results.

and if we add regularization to the cost function, we get the following results
