Submission GuidelinesIdea:
In forecasting and in commercial/sme risk scoring there is a need for trying vast number of algebraic equations which is a very cumbersome prosess. Let's add symbolic regression as a new competitive capability.
Rationale:
Summations, ratios, power transforms and all combinations of a like are needed to be tested as new variables for a forecasting or prediction model. Doing this by hand manually is a though and long business... And there is always a possibility for one to skip a valuable combination.
Symbolic regression is a novel techinique for automatically generating algebraic equations with use of genetic programming,
In every evolution a variable is selected checked if the equation is discriminatitive of the target variable at hand. In every next step frequently observed variables will be selected more likely.
Benefit for clients:
This method produces variables mainly with nonlinear relationships. It is a technique that will help in corporate/commercial/sme risk modelling, such that powerful risk models are generated from a hort list of B/S and P/L based algebraic equations.
There is potential use cases in algorithmic trading as well...
There are 3 very interesting world problems solved with symbolic regression here.
A very relevant thesis by sean Wouter is attached as a pdf document for your reading pleasure...
R side of things:
I've found Rgp package for genetic programming, here is a link.
Competition:
I haven't seen something similar in SAS, SPSS but there is this; http://www.nutonian.com/products/eureqa/
Also there is Bruce Ratner's page
