# Recommendation on Amazon Health (IID) (Recall@20, NDCG@20) Source: [Recommendation on Amazon Health (IID) (Recall@20, NDCG@20)]() Collection index: [llms.txt]() Data updated: 2026-02-26T06:01:38.305Z Evaluation of Recommendation performance on the IID split of the Amazon Health dataset, specifically reporting Recall@20 and NDCG@20. 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 | Recommendation | | Dataset (including any stated split) | Amazon Health (IID) | | Metric | Recall@20 | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 18 of 18 | | 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 - [Recall@20](): Higher is better; unit: PERCENT. - [NDCG@20](): Higher is better; unit: PERCENT. ## Recorded results | Method | Recall@20 | Result date | Report paper | | --- | --- | --- | --- | | DSL | 18.75 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | DSL | 18.71 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | AdvInfoNCE | 17.57 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | SL@K | 17.56 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | SL | 17.49 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | BSL | 17.49 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | SL@K | 17.23 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | PSL | 17.13 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | AdvInfoNCE | 17.04 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | SL | 17.03 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | BSL | 17.03 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | LLPAUC | 16.58 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | LLPAUC | 16.27 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | PSL | 16.19 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | GuidedRec | 14.78 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | GuidedRec | 13.58 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | BPR | 12.4 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | | BPR | 11.77 | Not recorded | 698abbb6c97a0b3e3b5de0a9 | ### DSL Recall@20: 18.75.
