Strip set from right
Retrieve per-variable split information for a given Isolation Forest model.
Output will include:
- count - The number of times a variable was used to make a split.
- aggregated_split_ratios - The split ratio is defined as "abs(#left_observations - #right_observations) / #before_split".
Even splits (#left_observations approx the same as #right_observations) contribute
less to the total aggregated split ratio value for the given feature;
highly imbalanced splits (eg. #left_observations >> #right_observations) contribute more.
- aggregated_split_depths - The sum of all depths of a variable used to make a split. (If a variable is used
on level N of a tree, then it contributes with N to the total aggregate.)
This function will add a new column rank where the ranking is produced as follows:
1. sorts the H2OFrame by columns sorted in by columns specified in group_by_cols and sort_cols in the directions
specified by the ascending for the sort_cols. The sort directions for the group_by_cols are ascending only.
2. A new rank column is added to the frame which will contain a rank assignment performed next. The user can
choose to assign a name to this new column. The default name is New_Rank_column.
3. For each groupby groups, a rank is assigned to the row starting from 1, 2, ... to the end of that group.
4. If sort_cols_sorted is TRUE, a final sort on the frame will be performed frame according to the sort_cols and
the sort directions in ascending. If sort_cols_sorted is FALSE (by default), the frame from step 3 will be
returned as is with no extra sort. This may provide a small speedup if desired.
