The autoencoder, a well-known neural network model, is usually fitted using a mean squared error loss or a cross-entropy loss. Both losses have a probabilistic interpretation: they are equivalent to maximizing the likelihood of the dataset when one uses a normal distribution or a categorical distribution respectively. We trained autoencoders on image datasets using different distributions and noticed the differences from the initial autoencoder: if a mixture of distributions is used the quality of the reconstructed images may increase and the dataset can be augmented; one can often visualize the reconstructed image along with the variances corresponding to each pixel.

• .py version
  • run "run.py"; this calls "main.py" with all the possible values for the command line arguments; if you encounter problems because of the indentation, consider using "main-weird-indent.py" instead of "main.py"

  • run for a given set of arguments the code interactively
