Introduction to Eureqa (1/2)

Eureqa is a software tool for detecting equations and hidden mathematical relationships in your data. Its primary goal is to identify the simplest mathematical formulas which could describe the underlying mechanisms that produced the data. Eurequa is free to download and use: http://ccsl.mae.cornell.edu/eureqa

I am really excited by the possibilities this algorithm offers. I thought it rather interesting that the program modeled an exponentially decreasing phase term. I have not seen anything like that before.

Is there any reason to think this could not be applied to a GPU to make the searches even faster?

Has anyone tried using Eureqa to tease meaning out of large sets of demographic or polling data? Any other Social Science applications?

How about releasing the source code for this program ?

Could it be that this is a simple star search of combinations of functions?

An almost brute strength technique abusing the speed of modern computers...

i'm going to use it on behavioural data from 1300 ppl where there are patterns that standard psychological analyses obscure.. hoping to get this done at Easter. i'll tell u how i get on if u want. Goodbye SPSS :)

This looks like it's a user interface for a genetic algorithm. Is it?

I wonder how this could be made to work categorical data? How would one define the function and fitness metric for y as probabilities?

Very cool. After an overnight form it found a form of the equation that's equivalent to what I had in mind.

I'm trying to let eureqa fit a rational equation ( ax/(b+x)+c ) and it seems to be having quite some trouble discovering it. Should I let it run overnight?

The ordering of solutions by complexity is ... ingenious. I wonder how efficient this will be modeling complex models to some really noisy data (log-periodic exponential growth for stock market crashes).
