  • Increase the value of NumBoostedTrees (the number of parallel boosted trees to consider during prediction).

    Each vworker processes each of its assigned tree-boosting operations sequentially. When you increase the value of NumBoostedTrees, each boosting operation operates on smaller subset of input data.

  • Decrease the input data footprint by minimizing the number of columns.
  • Decrease the size of a tree in memory by adjusting the values of these arguments:
    • MinNodeSize
    • MaxDepth
    • ColumnSubSampling
