0.238 Spectral angle (median over spectra, shared canonical fragment space)

Methods

Tested configuration: PredFull retrained on MassIVE-KB (PepSpecBench)
Protocol: PepSpecBench E. coli OOD subsets (both sources aggregated), median SA
Dataset: PepSpecBench E. coli OOD subsets (both sources aggregated)
Procedure: PepSpecBench E. coli OOD subsets (both sources aggregated), median SA
Evaluation: PredFull (trained on MassIVE-KB) on E. coli OOD subsets (both sources aggregated), SA
Coverage: Not reported scored / Not reported eligible
Uncertainty: Not reported by the source

A source-checked result verifies the numerical transcription, not every model or protocol detail. Evaluation metadata: source checked. Source checked does not mean independently reproduced.

Reproduction

Split: OOD (zero-shot)
Adaptation: Retrained on MassIVE-KB; no adaptation to the evaluation set
Scoring implementation: SA in the shared canonical fragment space

No execution recipe has been verified for this exact configuration and evaluation. A benchmark's general instructions may use different inputs, splits or model settings.

Reproducing this published result requires matching its model configuration, data, split and scorer. Source checking or a successful smoke test does not establish score reproduction.

Evidence

Source checking verifies the cited claim or transcription. It does not establish independent reproduction.

Evidence table

Inspect claims, sources and review details

Trace each statement to its source and review. A context-only reference supports the record generally; it does not verify an individual field. Source checking does not reproduce an experiment.

One row per statement and cited source. Multiple citations are not independent evaluations. Shared locators are labelled explicitly.
