当LightGBM.cv时,如果min_data_in_leaf设置的值比默认值(20)小的时候,就会报错: LightGBMError: Reducing `min_data_in_leaf` with `feature_pre_filter=true` may cause unexpected behaviour for features that were pre-filtered by the larger `min_data_in_leaf`. You need to set `feature_pre_filter...

@nirupamkarboth min_data_per_group and min_data_in_leaf do not consider the sample weights. you can usemin_sum_hessian_in_leafto replace themin_data_in_leaf, for sample weights. As formin_data_per_group, there is no replacement for now. @guolinkeThanks for the reply. Could you please...
minimum sum of instance weight (hessian) needed in a child. If the tree partition step results in a leaf node with the sum of instance weight less than min_child_weight, then the building process will give up further partitioning. In linear regression mode, this simply corresponds to minimum...
