# Information Retrieval on NFCorpus (Leakage, Confidence, NDCG@10) Source: [Information Retrieval on NFCorpus (Leakage, Confidence, NDCG@10)]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:48:33.895Z Evaluation of Information Retrieval performance on the NFCorpus dataset, focusing on metrics including Leakage, Confidence, and Downstream NDCG@10. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Information Retrieval | | Dataset (including any stated split) | NFCorpus | | Metric | Leakage | | Unit | SCALAR | | Direction | Lower is better | | Results loaded | 16 of 16 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [Leakage](): Lower is better; unit: SCALAR. - [Confidence](): Higher is better; unit: SCALAR. - [NDCG@10 (Downstream)](): Higher is better; unit: PERCENT. ## Recorded results | Method | Leakage | Result date | Report paper | | --- | --- | --- | --- | | SPARSE | 0.68 | Not recorded | 698abbaec97a0b3e3b5de035 | | LapMech | 7.77 | Not recorded | 698abbaec97a0b3e3b5de035 | | PurMech | 8.45 | Not recorded | 698abbaec97a0b3e3b5de035 | | SPARSE | 12.16 | Not recorded | 698abbaec97a0b3e3b5de035 | | LapMech | 29.73 | Not recorded | 698abbaec97a0b3e3b5de035 | | PurMech | 31.42 | Not recorded | 698abbaec97a0b3e3b5de035 | | SPARSE | 46.96 | Not recorded | 698abbaec97a0b3e3b5de035 | | PurMech | 55.41 | Not recorded | 698abbaec97a0b3e3b5de035 | | LapMech | 56.76 | Not recorded | 698abbaec97a0b3e3b5de035 | | SPARSE | 57.77 | Not recorded | 698abbaec97a0b3e3b5de035 | | SPARSE | 66.55 | Not recorded | 698abbaec97a0b3e3b5de035 | | PurMech | 69.26 | Not recorded | 698abbaec97a0b3e3b5de035 | | LapMech | 69.93 | Not recorded | 698abbaec97a0b3e3b5de035 | | LapMech | 78.72 | Not recorded | 698abbaec97a0b3e3b5de035 | | PurMech | 79.05 | Not recorded | 698abbaec97a0b3e3b5de035 | | Non-protected | 88.18 | Not recorded | 698abbaec97a0b3e3b5de035 | ### SPARSE Leakage: 0.68.
