The minimum sum of instance weight needed to form a new node.

public double MinimumChildWeight;
val mutable MinimumChildWeight : double
Public MinimumChildWeight As Double

Field Value

Double

If the tree partition step results in a leaf node with the sum of instance weight less than MinimumChildWeight, the building process will give up further partitioning. In linear regression mode, this simply corresponds to minimum number of instances needed to be in each node. The larger, the more conservative the algorithm will be.
