I am training a random forest with 10 features and 1 continuous target variable. When I train the random forest with 10 trees, everything works successfully. When I increase the number of trees to 50 or 100, I get ap_error. my code is: ae_int_t ntrees = 50; ae_int_t mtry = 6; fraction = 0.5; decisionforestbuilder builder; ae_int_t nvars = 10; ae_int_t nclasses = 1; ae_int_t npoints = train_size; dfbuildercreate(builder); dfbuildersetdataset(builder, train_data, npoints, nvars, nclasses); dfbuildersetrndvars(builder,mtry); dfbuildersetseed(builder, 1); dfbuildersetsubsampleratio(builder, fraction); dfreport rep; dfbuilderbuildrandomforest(builder, ntrees, model, rep); What can this error be? |
