0.39 ± 2 × 10 − 2 Perturbench cosine logfc

Methods

Tested configuration: LA
Protocol: PerturBench v4 covariate transfer of small-molecule effects across PBMC cell types on OP3
Dataset subset: OP3 (PerturBench v4 split)
Procedure: PerturBench v4 covariate transfer of small-molecule effects across PBMC cell types on OP3
Evaluation: LA on PerturBench v4 op3
Coverage: Not reported scored / Not reported eligible
Uncertainty: SD 0.02
Evidence: Author-reported evaluation · source checkedPerturBench: Benchmarking Machine Learning Models for Cellular Perturbation Analysis (arXiv v4) · Table 9, row 'LA', column 'Cosine LogFC'

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: OP3 small-molecule perturbations in primary PBMC cell types, split from the NeurIPS 2023 challenge train, public and private test partitions.
Adaptation: Trained from scratch per dataset with HPO
Scoring implementation: PerturBench evaluation module (Section 4.2)

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.
