I think it's awesome you've gone through all of that effort in making the RF model avialable. I'm curious ... at the very top of the Random Forests website they make the following statement:
"Random Forests(tm) is a trademark of Leo Breiman and Adele Cutler and is licensed exclusively to Salford Systems for the commercial release of the software. Our trademarks also include RF(tm), RandomForests(tm), RandomForest(tm) and Random Forest(tm)."
This seems to imply some animosity towards those wanting to apply this mathematical method for profit without consent of the "owners" of the idea (with all the fuzzyness inherent in I.P. law of the trade secret variety).
I suspect that RF is at least partially, if not fully, behind most of the highest scores on the board. I was not familiar with the technique until reading these forums, and I do not use R, but was thinking about implementing a RF like algorithim in Mathematica
(which has all sorts of tree-graph visualization and manipulation tools built-in) - but I'm curious: if a winner of this competition uses an RF model without the consent of Breiman, Cutler and or Salford will they be open to legal action?
Thanks again for your hard work, your posts are generally very enlightening.
