After 200 iterations of updates using minFunc, your autoencoder should have learned features that resemble pen strokes. Our implementation takes around 25-30 minutes on a fast machine. Visualized, the features should look like in the following image: | After 200 iterations of updates using minFunc, your autoencoder should have learned features that resemble pen strokes.
