Gaussian discriminant classification with class-specific covariance matrices.

Identity Notes & Concept Scope Classification does not specify Gaussian class models with class-specific covariance.

Claims & Grounded Evidence

1 Claim

Mechanism #mechanism

Gaussian class-conditional distributions use separate covariance matrices, allowing quadratic decision boundaries.

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.
