>The paper itself describes the possibility that aspects of the online learning ability (the ability to integrate new data as it is received without the costly requirement of retraining) could be implemented in a fully analog system through a cross-point array of resistors, instead of applying a digitally-bound algorithm. So both theoretical and materials design space still covers a number of potential, future exploration venues. That is very cool. Feels like a nuevo tape drive for neural networks.
