[edit: last update at 2014/06/27. My apologies, have been very busy the past few months.]

We learn more from code, and from great code. Not necessarily always the 1st ranking solution, because we also learn what makes a stellar and just a good solution. I will post solutions I came upon so we can all learn to become better!

I collected the following source code and interesting discussions from the Kaggle held competitions for learning purposes. Not all competitions are listed because I am only manually collecting them, also some competitions are not listed due to no one sharing. I will add more as time goes by. Thank you.

Rank 1 solution by Leustagos.

Solution thread here.

Rank 2 solution by Iain Murray, code available here.

Rank 6 solution by Shea Parkes & Neil Schneider team.

Rank 17 solution of Ensemble of RandomForests, GradientBoostingTrees and ExtraTreesRegressor by Emanuele Olivetti.

Thank you Foxtrot, James Petterson, Ben S for providing some of the links and solutions above.
