Torchhd: An Open-Source Python Library to Support Hyperdimensional Computing Research
share
Hyperdimensional Computing (HDC) is a neuro-inspired computing framework that exploits high-dimensional random vector spaces. HDC uses extremely parallelizable arithmetic to provide computational solutions that balance accuracy, efficiency and robustness. This has proven especially useful in resource-limited scenarios such as embedded systems. The commitment of the scientific community to aggregate and disseminate research in this particularly multidisciplinary field has been fundamental for its advancement. Adding to this effort, we propose Torchhd, a high-performance open-source Python library for HDC. Torchhd seeks to make HDC more accessible and serves as an efficient foundation for research and application development. The easy-to-use library builds on top of PyTorch and features state-of-the-art HDC functionality, clear documentation and implementation examples from notable publications. Comparing publicly available code with their Torchhd implementation shows that experiments can run up to 104× faster. Torchhd is available at: https://github.com/hyperdimensional-computing/torchhd
