I am trying Gradient Boosting Classifier for my project. I am using 100 samples. I have used Leave one out cross validation. As far as i know, GBC should give good results with large n_estimators. But i am getting low results with large n-estimators.Where am i going wrong. Thank you I have tried the following:
tried:n_estimators=100, learning_rate=1.0,max_depth=1, random_state=0 result:Accuracy=0.635416666667 AUC=0.5703125
tried: tried:n_estimators=200, learning_rate=1.0,max_depth=1, random_state=0 result:Accuracy=0.625 AUC=0.5546875
tried:n_estimators=1, learning_rate=1.0,max_depth=1, random_state=0 result:Accuracy=0.739583333333 AUC=0.6640625
