stable_cart.split_features¶
- stable_cart.split_features(model, max_depth=3)[source]¶
Return the multiset of features tested down to a given depth.
A multiset rather than a set: a feature tested at three different nodes is a more central part of the explanation than one tested once, and collapsing that to a set would hide it.
Parameters¶
- model
A fitted tree.
- max_depth
Deepest level to include; the root is level 0.
Returns¶
- Counter
Feature index -> number of nodes testing it.
