DF_pred {Dforest}

Decision Forest algorithm: Model prediction

Description

Decision Forest algorithm: Model prediction with constructed DF models. DT_models is a list of Decision Tree models (rpart.objects) generated by DF_train() DT_train_CV() is only designed for Cross-validation and won't generate models

Usage

DF_pred(DT_models, X, Y = NULL)

Arguments

DT_models

Constructed DF models

X

Test Dataset

Y

Test data endpoint

Value

.$accuracy: Overall test accuracy

.$predictions: Detailed test prediction

Examples

  # data(demo_simple)
  X = data_dili$X
  Y = data_dili$Y
  names(Y)=rownames(X)

  random_seq=sample(nrow(X))
  split_rate=3
  split_sample = suppressWarnings(split(random_seq,1:split_rate))
  Train_X = X[-random_seq[split_sample[[1]]],]
  Train_Y = Y[-random_seq[split_sample[[1]]]]
  Test_X = X[random_seq[split_sample[[1]]],]
  Test_Y = Y[random_seq[split_sample[[1]]]]

  used_model = DF_train(Train_X, Train_Y)
  Pred_result = DF_pred(used_model,Test_X,Test_Y)
