I had similar feelings about William Pearson's recent message aboutsystems that use reinforcement learning: A reinforcement scenario, from wikipedia is defined as "Formally, the basic reinforcement learning model consists of: 1. a set of environment states S; 2. a set of actions A; and 3. a

Richard, Can you explain differently, in other words the second part of this post. I am very interested in this as a large part of an AI system. I believe in some fashion there needs to be a controlling algorithm that tells the AI that it is doing "Right" be it either an internal or external human

James, It is a little hard to know where to start, to be honest. Do you have a background in any particular area already, or are you pre-college? If the latter, and if you are interested in the field in a serious way, I would recommend that you hunt down a good programme in cognitive

Phil, But the visual calculations below only give you the flow going back to the visual cortex: didn't you specifically want the frontal lobes? Given that you could go into a sensory-deprivation tank and yet still get a good flow into your frontal lobes, how would you know what proportion

It IS my contention that there is a relatively simple, inductively-robust (in a mathematical proof sense) formulation of friendliness that will guarantee that there won't be effects that *I* consider undesirable, horrible, or immoral. It will, of course/however, produce a number of effects

William, 1) I agree that direct reward has to be in-built (into brain / AI system). 2) I don't see why direct reward cannot be used for rewarding mental achievements. I think that this direct rewarding mechanism is preprogrammed in genes and cannot be used directly by mind. This mechanism

Various people have the notion that events, concepts, etc., are represented in the brain as a combination of various sensory percepts, contexts, subconcepts, etc. This leads to a representational scheme in which some associational cortex links together the sub-parts making up a concept or a
