Скачать или смотреть Vector Quantized Variational AutoEncoder (VQVAE) From Scratch

Code: https://github.com/priyammaz/PyTorch-...

To continue on our AutoEncoder adventure, we move onto the VQVAE! We wont spend too much time here training the models, we will just look at the results, as the training code is basically identical to everything we did earlier in our AutoEncoder Tutorial    • Intro To AutoEncoders: Compression is Ever...   and our VAE tutorial    • Variational AutoEncoders (VAE) Implementation  .

Quantization is a powerful tool, especially leveraged in Neural Speech processing and Generative Models, so I wanted to give an introduction here! Its all about keeping backprop alive!
