Yes, if I had claimed they were analogous. I said merely that it "reminds me of", in the simple sense that those who don't grok theory tend to denigrate it. > UAI so far has yet to prove its usefulness.

This is intriguing, but unclear to me. Does it entail anything consequential beyond the statement that Solomonoff induction is incomputable?

The terms and grammar were legitimate, but I couldn't translate the claims to any workable model of reality -- I actually expected to see Sokal mentioned as co-author -- but upon googling I found the following paper in response, which in comparison was quite comprehensible. <http://www.macs.hw.ac.uk/~greg/publications/cm.cj07.pdf> I'd be interested in knowing whether (and how) you think the response paper gets it wrong. - Jef ----- This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?member_id=8660244&id_secret=63742336-b30226
