While artificial intelligence (AI) has paved its way to some bionic applications mostly through software post-processing, close to none of today's electronic implants can be named "Intelligent"! We believe with the large amount of data that is available in any medical field and remarkable advances in AI and the expertise that we have in that as well as electronic technology shrinkage to a remarkable scale, there is a real chance that we may ultimately be able to let an implant to "learn and understand" streams of neural data and make decision with high accuracy. There are software and hardware expertise exist in our side that requires to be matched with medical knowledge, expertise and data. With that in mind please find the following proposal for collaboration [1-4].

This project aims to (A) introduce a deep learning platform for prediction of anomalies before it causes alteration of consciousness or other damages, (B) implement an ultra-low power fully digital and fully customized chipset to parallel achieved software performance, (C) mitigate problems of ‘false alarms' and ‘delay in action' confirmed using a set of clinical trials.

This project uses our state-of-the-art GPU cluster to develop the software and integrated circuit design tools to explore hardware implementation. We also study packaging and high-level integration and surgery issues for full animal clinical trial.
