Hi Angli, @HsiaoChiLiao might be the best person to ask here. I didn't change much from her original xgboost code.
nrounds
is a parameter (the number of decision trees used in the model) that XGBoost uses for feature selection/prediction. It's not used for calculating TP. 😊
Hi Ray,
I am trying to explain why the TP in xgboost is often higher in geneBasis.
Do you remember why the
nrounds
is set as 1500 by default?I called the original function but found that:
performanceAllMarkers()
calledperformanceMarkers()
, and thenperformanceMarkers()
calledxgboostPerformance()
It seems this parameter is not passed to the final function because
performanceMarkers()
didn't accept this parameter in line #50.
