Therefore you can build good quantitative predictors just treating environment as noise. The problem is to extract the parameters in the models (see Turing quote).steve hsuhttp://plus.google.com/u/0/+StephenHsu/aboutnoreply@blogger.comtag:blogger.com,1999:blog-5880610.post-6159484291461544862015-01-14T08:23:54.096-05:002015-01-14T08:23:54.096-05:00http://infoproc.blogspot.com/2014/11/adaptive-evol...http://infoproc.blogspot.com/2014/11/adaptive-evolution-and-non-coding.htmlsteve hsuhttp://plus.google.com/u/0/+StephenHsu/aboutnoreply@blogger.comtag:blogger.com,1999:blog-5880610.post-54784685930676589402015-01-14T08:19:52.166-05:002015-01-14T08:19:52.166-05:00PS.

It's similar to the claim (now a movie with the gorgeous Scarlet Johannsen) that we only use 10% of our brain (note the same numerology in both cases). Obviously, an organ as expensive as a brain is utilized 100%. Even the sleep/dream time has a use.BobSykesnoreply@blogger.comtag:blogger.com,1999:blog-5880610.post-50333930035029555782015-01-14T08:17:40.059-05:002015-01-14T08:17:40.059-05:00The real puzzle is what all the DNA that doesn'...The real puzzle is what all the DNA that doesn't code protein (90% or so) does. This is rapidly being worked out, and no doubt the whole control system will be known in detail in a few decades. However, the prediction problem is, How does this system interact with the environment? Even well-constrained algorithms like the number of fingers and toes is environment independent, apparently BobSykesnoreply@blogger.comtag:blogger.com,1999:blog-5880610.post-92063859219252544152015-01-14T05:55:42.534-05:002015-01-14T05:55:42.534-05:00Whenever I encounter models in other fields, I alw...Whenever I encounter models in other fields, I always build analogies back to physics.This is usually helpful and often reveals entire strands of thought that researchers in other fields have barely considered.<br /><br />However, whenever I encounter anything resembling a market, I find that asset pricing theory provides the best framework.
