WebOct 7, 2024 · To train on the dataset using a DMatrix, we need to use the XGBoost train () method. The train () method takes two required arguments, the parameters, and the DMatrix. Following is the code for training using DMatrix. Using the above model, we can also predict the survival classes on our validation set. Webslice (rindex, allow_groups=False) ¶. Slice the DMatrix and return a new DMatrix that only contains rindex.. Parameters. rindex – List of indices to be selected.. allow_groups (boolean) – Allow slicing of a matrix with a groups attribute. Returns. res – A new DMatrix containing only selected indices..
