Ordering of data points within each group, so it doesn’t make This is because we only care about the relative In ranking task, one weight is assigned to each group (not eachĭata point). Label ( array_like) – Label of the training data.

Which is optimized for both memory efficiency and training speed. DMatrix ( data, label = None, *, weight = None, base_margin = None, missing = None, silent = False, feature_names = None, feature_types = None, nthread = None, group = None, qid = None, label_lower_bound = None, label_upper_bound = None, feature_weights = None, enable_categorical = False ) ĭMatrix is an internal data structure that is used by XGBoost,
