Mahalanobis feature-distance detection for anomalies and adversarial samples

Fits class means and a tied feature covariance, then combines layer-wise Mahalanobis scores with input preprocessing to detect anomalous or adversarial examples from pretrained representations.

What is recorded here?

Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.

Scientific scope

Gaussian-discriminant interpretation is an assumption/model, not proof that arbitrary learned features are Gaussian. Layer ensemble weights and preprocessing use validation data; empirical detection is not certified resistance to adaptive attacks. Mahalanobis distance itself is inherited.
