It's also a mistake that got some psudonymous victim of Dunning Kruger at ycombinator claiming I was mentally ill when I suggested the possibility of a business sector exploiting the current ignorance of plausibly practical applications of Solomonoff Induction. He kept coming back saying "AIXI" and "diagnosing" me, even after I tried disabusing him of his conflation. (This behavior is quite common in AGI discussions and is really quite weird as I've previously indicated.) > Good predictors (including AIXI, other AI, and lossless compression) > are necessarily complex... > Two examples: > 1.

The dynamical models _produced_ by SINDy do not contain the library of different functions contained in the SINDy program. It is the dynamical models produced by AIT that do the predicting when called upon by the SDT aspect of AIXI. ------------------------------------------ Artificial General Intelligence List: AGI Permalink: https://agi.topicbox.com/groups/agi/Taf667527679b18c3-M460aa1b85a839a6da618c8ac Delivery options: https://agi.topicbox.com/groups/agi/subscription
