Paper H3

Roadmap

  • Include H3, LLM training, and synthetics in this repository
  • Move in fast convolution code
  • Add Hyena implementation and experiments
  • pip package

See CHANGELOG.md

Setup

Requirements

This repository requires Python 3.8+ and Pytorch 1.10+. Other packages are listed in requirements.txt.

Getting Started

The easiest way to get started is to run the standalone_cifar.py script. This scripts trains a simple long convolution model on CIFAR-10:

python -m standalone_cifar

See the experiments page for more:

  • LRA experiments from the Long Convs paper
  • H3 experiments (language model, synthetics)
  • H3 + Long Conv experiments
  • Hyena language and vision experiments
