This is a collection of simple PyTorch implementations of
neural networks and related algorithms.
These implementations are documented with explanations,
and the [website](https://lab-ml.com/labml_nn/index.html)
renders these as side-by-side formatted notes.
We believe these would help you understand these algorithms better.

We are actively maintaining this repo and adding new 
implementations.
