[agi] inference methods

[Pablo Carbonell]

Hi,



Im currently
studying econometric methods... those are supposed to find patterns in series
of variables.



There are other
approaches for finding patterns in data, like neural networks.



What I wonder is, a
neural network could do the job of econometric methods?



Any ideas?



Thank you!

Pablo

Hi,



I
think its the first time i see here a post written by a woman 
welcome, Margeret!

This is interesting. What I like about it is that it
also demonstrates the serendipitous nature of scientific discoveries.

Peace!

Re: [agi] general patterns induction

[Pablo Carbonell]

oh tanks a lot, would you please email it to me!!?

 
 Pablo,
 
 If you are interested in Solomonoff induction and don't 
want to
 spend all the money to buy the book just yet then you 
might be
 interested in a paper I wrote a few years back that starts 
from
 basic computation theory and proves all the key results.
 It about 25 pages of mathematics in PDF format, I can 
email it
 to you if you like.
 
 The key points are:
 
 Solomonoff induction will learn anything that is 
computationally
 expressible (i.e. anything useful) with an error rate that falls
 to zero faster than 1/n where n is the number of bits of 
input
 data that the system has been given.
 
 Solomonoff induction is not computable and it is difficult to
 approximate well.
 
 Most learning methods in statistics and machine learning 
can in
 some sense be proven to be computable approximations 
to Solomonoff
 induction.
 
 
 So, in short, it's an interesting theoretical model that's 
amazingly
 powerful but it's not something you can directly use in 
practice.
 The prize for an amazingly powerful and practical system is 
still
 very much up for grabs :)
 
 If you're serious about data compression also check out a 
book
 called Text Compression by Bell, Cleary and Witten.
 
 Cheers
 Shane
