MGL-GPR is no longer a Genetic Programming only library because it got an another Evolutionary Algorithm implementation: Differential Evolution. My original plan for this contest was to breed input features that the physicists in their insistence on comprehensibility overlooked, but it didn't work as well as I had hoped for reasons specific to this specific contest and also because evolutionary algorithms just do not scale to larger problem sizes.
In other news, MGL got cross-validation, bagging and stratification support in the brand new MGL-RESAMPLE package documented with MGL-PAX which all of you will most definitely want to use. My winning submission used bagged cross-validated dropout neural networks with stratified splits so this is where it's coming from.Read more
