**1024-256-64-**__8__**-64-256-1024**], which means that a 1024 Dimension image is being compressed to just 8 Dimensions. And in the second part of the image it can be seen how well the 'Auto-Encoder' is able to reconstruct the 'Original' image. Just beside that, we can see how badly PCA algorithm reconstructs the same image after compressing the original image to 8 Dimensions (i.e. taking first 8 principal components only).

PS: Auto-Encoder compression and PCA are **NOT loss-less** compression techniques
