Instance Constructors

  1. new QuantileDMatrix(iter: Iterator[ColumnBatch], refDMatrix: QuantileDMatrix, missing: Float, maxBin: Int, nthread: Int)

    Create QuantileDMatrix from iterator based on the cuda array interface

    Create QuantileDMatrix from iterator based on the cuda array interface

    iter

    the XGBoost ColumnBatch batch to provide the corresponding cuda array interface

    refDMatrix

    The reference QuantileDMatrix that provides quantile information, needed when creating validation/test dataset with QuantileDMatrix. Supplying the training DMatrix as a reference means that the same quantisation applied to the training data is applied to the validation/test data

    missing

    the missing value

    maxBin

    the max bin

    nthread

    the parallelism

    Exceptions thrown
