MW/MT: Correct me, but I haven't seen any awareness in AI of the huge difficulties that result from the problem of : how do you test acquired knowledge?
MW:You're missing seeing it. It's generally phrased as "converting data to knowledge" or "concept formulation" and it's currently generally envisioned more as a problem of how do you do it (acquire knowledge and store it) than how do you test that you've been successful at it (since it's tough to test something that you don't even know how to do yet). The AI field is very aware of this problem but it's almost a cart before the horse problem. Once we know how to acquire and store knowledge, then we can develop metrics for testing it -- but, for now, it's too early to go after the problem. This is interesting. I strongly suspect AI has it very wrong. We're recognising that perception is not as was once thought fairly passive reception of impressions, later checked and corrected by the rational brain, but active exploration and intelligent from the v. beginning. You describe AI, probably correctly, as passively registering and then organising facts and only then - only it hasn't yet got around to that stage - testing them. Actually, I suspect, human knowledge-gathering is from the beginning active and exploratory - i.e. we begin with questions about the knowledge we're gathering, (whether in a book or in, say conversations or watching a movie), make predictions as we go along, and continuously test them. Day-to-day individual knowledge-gathering, if this is correct, is v. like the collective knowledge-gathering of science. The passive approach seems more logical and simpler, but the active approach is in fact much more practical and essential. I would hazard that this might be in part because we don't have outside helpers as AI/AGI systems do giving us a categorical/filing structure for info. beforehand, but have to create one on the fly - and so should a true AGI. Something to do with: "if you teach someone, they'll never learn." But these are areas which I'm just starting to dip into.
