Directory structure

The important files are as follows:

• generate_block_bezier_dataset.py constructs the training data for the VQ-VAE
• train_vqvae.py actually trains the VQ-VAE
• generate_random_plane_2_dataset.py constructs the training data for the transformer
• train_transformer_5.py actually trains the transformer

Why all the files?

I made quite a few attempts with various methods, so I left those methods in the repository. For example, the src/encoder_decoder folder and train_encoder_decoder.py file contains an attempt at writing a different kind of autoencoder for images where the decoder is not a convolution network but instead an autoregressive next token predictor. The src/diffusion contains a similar attempt where the decoder is a diffusion network.

Credits

• The src/nanogpt folder is largely taken from Andrej Karpathy's nanoGPT project.
• The src/diffusion_2 folder is cloned from milmor/diffusion-transformer and includes the original files and license.
