[QUOTE="-jeffB, post: 7973557, member: 27832"]I'm sorry, but that's just not true. [B]You only see news releases[/B] about the applications where it fares well -- or, occasionally, the ones where it fails spectacularly. You're also throwing in a bit of circular reasoning, where "ever[y] task in intelligence that it is applied to" only includes tasks where it performs well, because [I]nobody applies it to tasks where it performs poorly[/I]. Or, if they do, they don't brag about it. Neural nets are [I]inspired by[/I] the [I]organization of[/I] biological nervous systems. They aren't "based on" "biological intelligence". They do "learn", or rather "get trained"; the process is somewhere between training a dog to sniff for drugs, and "training" water to cut gullies as it flows down a sandy hill.
