Neural Decoding for Patients with Upper Limb Paralysis

Inspired by the experiment of Elon Musk’s Neuralink, where the monkey could play video games with its brain, we implemented two algorithms for neural decoding, the Long Short-term Memory Networks and the Kalman Filter, in our course project of Neural Implants & Interfaces.
