Hi Betrand Thanks for the reply. Well, what i have is n correlation matrices of the brain (n is the number of participants in the study). The simplest kernel computes the dot product between the n matrices. The kernel is further optimized using the NIPALS algorithm (as in Rosipal, Trejo 2002) The

[scikit-learn] OOB decision function in RandomForestClassifier

2018-03-09 Thread Stephen Jeffrey via scikit-learn
Hi, When using RFC on a multiclass problem with a large number of trees, would you expect the prediction for a given sample to match the OOB decision function i.e. should the prediction match the class with the highest OOB value for the given sample, when n_estimators is large? On my 3-class pro
