Algorithms AIMech:C45 DRAFT

Decision-tree induction extending ID3 with tests on continuous-valued features.

Identity Notes & Concept Scope DecisionTree does not identify this extension of ID3 handling continuous features.

Claims & Grounded Evidence

1 Claim

Mechanism #mechanism

Continuous features can be split into discrete intervals while extending the ID3 tree-induction approach.

This record supports method identity and the stated mechanism only; no universal performance or biological efficacy claim is curated.
Proposed placement is an inference from the existing AIO hierarchy; maintainers must resolve task, algorithm and model scope before acceptance.
