I understand that before back propagation was developed there were other methods used such as hebbian learning, and admittedly I know nothing about these old methods.
But as I've learned about back prop in wondering is there a line of research working on alternatives? It seems amazing but also so highly incremental and blind that I wonder if there's a better way.
One of it's major drawbacks is the fact that the information must pass through the entire structure rather than getting immediate feedback.
Anyway, thanks!
