Dear expert,
I’m using TMVA multi-regression, I got the following warning:
— MLP : ANN too complicated: #events=991 #synapses=1164
I find very little instruction about how to use regression, so I set the parameters to the ones used in tmva regression example:
factory->BookMethod( TMVA::Types::kMLP, “MLP”, “!H:!V:VarTransform=Norm:NeuronType=tanh:NCycles=2000:HiddenLayers=N+20:TestRate=6:TrainingMethod=BFGS:Sampling=0.3:SamplingEpoch=0.8:ConvergenceImprove=1e-6:ConvergenceTests=15:!UseRegulator” );
Could you please kindly let me know what does the warning mean and how to solve this problem?
Thanks,
Binghuan
