Auto Encoder(include sparse and denoiging one)

Implement auto encoder and observe hiddin layer and output layer's weight and output in auto encoder.
That's because I wanna know auto encoder actually shrinks data from datasets in its hidden layer.
I also implemented nomal 'auto encoder', 'sparse auto encoder' and 'denoising auto encoder' with MNIST dataset.

The result on the experiments is summarized in the following slide.
