AT, I suspect that there is some sort of new logic at work in Google, machine vision and other areas of pre-AGI, specifically...
Google FINALLY made their search engine look for all synonyms and variations of each word (unless you surround it with "quotes"). Machine vision often becomes much more useful when a "recognition" is redefined as an INability to eliminate the prospect of an object being present. This handily solves the partial obscurement challenges, unusual orientations, etc. I suspect that AGI-logic will become the process of manipulating POSSIbilities rather than manipulating Bayesian PROBAbilities. There is 100% probability of whatever is present being there, and 0% probability of objects that are not present being there. Only in VERY familiar circumstances are Chi Square computed conditional probabilities, Bayesian computations, etc. worth anything at all. Then, the process of learning becomes the discovery of which possibilities *might* be relevant, and which possibilities are clearly irrelevant. This has the possibility of sidestepping the "probabilities of probabilities of probabilities" conundrum, where you are trying to manipulate probabilities through a haphazard process that itself is full of probabilities of being grossly wrong. This has apparently sunk the implementation of practical learning of Bayesian computations. When you have eliminated the impossible, whatever remains, *however improbable*, must be the truth. Sherlock Holmes This approach runs into problems when there is insufficient information to eliminate multiple "truths" **AND** those truths lead to different actions that have different-valued outcomes. Perhaps we **MUST** be as complex as we are, just to be able to gather enough data to reduce the possibility-space down to a tractable size?!!! This could bode poorly for small implementations. Any thoughts?

Simply institute a six hour workday. That will easily create enough new jobs to bring back full employment. ------------------------------------------- AGI Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/21088071-f452e424 Modify Your Subscription: https://www.listbox.com/member/?member_id=21088071&id_secret=21088071-58d57657 Powered by Listbox: http://www.listbox.com
