Tools to losslessly compress and decompress raw neural data.

Neuralink Compression Challenge

Summary

content.neuralink.com/compression-challenge/data.zip is one hour of raw electrode recordings from a Neuralink implant.

This Neuralink is implanted in the motor cortex of a non-human primate, and recordings were made while playing a video game, like this.

Compression is essential: N1 implant generates ~200Mbps of eletrode data (1024 electrodes @ 20kHz, 10b resolution) and can transmit ~1Mbps wirelessly. So > 200x compression is needed. Compression must run in real time (< 1ms) at low power (< 10mW, including radio).

Neuralink is looking for new approaches to this compression problem, and exceptional engineers to work on it.

Task

Build executables ./encode and ./decode which pass eval.sh. This verifies compression is lossless and measures compression ratio.

Your submission will be scored on the compression ratio it achieves on a different set of electrode recordings. Bonus points for optimizing latency and power efficiency

Submit with source code and build script. Should at least build on Linux.
