VS: Reinforcement Learning

[Eetu Pikkarainen 2017-10-04]

Just to tell that I warmly second this formulation (which for me does not seem like reiteration of your former message but an improvement of it).

Btw I think that evolution IS learning, supra-subjective learning. Subjective learning starts where evolution has ended up. Powers thought that all (?) our control hierarchy is subjectively
learned – that is probably not quite true, some parts of it can bee evolved. But the systems controlling the intrinsic variables are certainly innate – even though perhaps they may also change by learning.

My personal view at the moment is that reorganization is the most important form of learning. (Powers mention also memory and problem solving as forms of learning, but for me the latter
does not seem so.) Reorganization invents new routes for neural signals but perhaps also some reinforcement or strengthening of the connections is needed. Many behaviors, even their references are perhaps alternatives: I can go by bus or by walking to the
goal place, I can make pasta or soup if I am hungry etc. I call it habitation when we learn to do things always in a certain way even though we could use other ways instead. This “reinforcementâ€? learning can be as simple as Hebbian-Anti-Hebbian learning (which
I have learned from Martin).
