A research team explores oblique conditions in its tree learner when single-feature splits cannot separate classes cleanly.
A risk modeling team avoids oblique conditions in production trees because single-feature axis-aligned splits are easier for reviewers to audit.
A research team uses oblique conditions in a research prototype to compare against axis-aligned trees on synthetic data.
