SOM: Self-Organizing Map

Pytorch implementation of Kohonen's Self-Organizing MAP.

• Fast direct updates with mini-batch on GPU (using optim is slow)
• Initialize map center with centroid of data

This code does not require nunif library.

python3 -m playground.som.train_mnist

The generated images are saved in tmp/som.

AE-SOM

Autoencoder based Deep Convolutional SOM that I designed at random.

python3 -m playground.som.train_aesom_mnist

It's less blurry.
