You are totally right. The algorithm itself is a potential game-changer. I guess I was carried away by the pitch in the abstract that starts off with deep learning.

Personally I think that way too many resources were wasted on trying to make better deep networks with spikes. In my opinion it is much more promising to apply spiking networks on problems that are inherently event-based.

Having a functional backpropagation algorithm such as the one provided can help with that, obviously.

Based on reading just the abstract so far, it seems to me the event-based application of this algorithm makes absolute sense. Temporal importance can be effectively characterized in memristors. At the risk of making a comparison similar to that of Andrew Ng's a decade ago, I think this approach paired with something like a ReRAM crossbar is quite an effective rough analogue to the voltage potentials across a group of neurons in the brain.

I applaud this team's efforts. A real breakthrough.
