Spectral Analytics Extensions¶

Module: spectralbridge.spectral_analytics_extensions.

Training-confined prototype, domain and withheld-class diagnostics.

Experimental audit outputs; no operational classification or purity guarantee.

Signatures and documentation below are collected from the current source. Advanced objects are not newly declared stable by inclusion here.

Audience: advanced.

checkpoint ¶

checkpoint(directory, identity, action)

Publish a stage ledger last; reject altered completed outputs.

Audience: advanced.

novelty_threshold(scores, identities, quantile=0.95)

Known-only higher empirical quantile of whole-identity maxima.

Audience: advanced.

unknown_metrics(is_unknown, scores, threshold)

Unknown precision/recall and known rejection at a prechosen threshold.

Audience: advanced.

safe_novelty_scores(values, training, space)

Keep zero selected-band spectra for distance/PCA; angle is undefined.

Audience: advanced.

run_extensions(source, compact, root, *, config=None)

Run declared secondary comparisons with per-fold restart checkpoints.

Audience: advanced.

run_domains(source, compact, root, *, config=None)

Predict observational domains on held-out identities, not instrument causes.
