When I use the word 'AIXI' above, I mean to include Solomonoff induction. I would have thought that was obvious.
One has to learn Solomonoff induction to learn AIXI.
AIXI is more than just Solomonoff induction. It is Solomonoff induction plus some other stuff. I'm a teensy bit concerned that you are giving AIXI credit for Solomonoff induction's moves.
I searched the posts but didn't find a great deal of relevant information. Has anyone taken a serious crack at it, preferably someone who would like to share their thoughts? Is the material worthwhile? Are there any dubious portions or any sections one might want to avoid reading (either due to bad ideas or for time saving reasons)? I'm considering investing a chunk of time into investigating Legg's work so any feedback would be much appreciated, and it seems likely that there might be others who would like some perspective on it as well.
