# Top-k Recommendation Performance on Amazon Beauty Source: [Top-k Recommendation Performance on Amazon Beauty]() Collection index: [llms.txt]() Data updated: 2026-04-13T07:29:52.648Z Evaluation of Top-k Recommendation models on the Amazon Beauty dataset, focusing on ranking metrics such as N@k (e.g., NDCG) and H@k (e.g., Hit Rate) for k=10 and k=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 | Top-k Recommendation | | Dataset (including any stated split) | Amazon Beauty | | Metric | NDCG@10 | | 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 - [NDCG@10](): Higher is better; unit: PERCENT. - [Hit Rate@10](): Higher is better; unit: PERCENT. - [NDCG@20](): Higher is better; unit: PERCENT. - [Hit Rate@20](): Higher is better; unit: PERCENT. ## Recorded results | Method | NDCG@10 | Result date | Report paper | | --- | --- | --- | --- | | Original | 20.36 | Not recorded | 69dc78877d0172140ec78a7b | | DITaR | 20.32 | Not recorded | 69dc78877d0172140ec78a7b | | Original | 20.29 | Not recorded | 69dc78877d0172140ec78a7b | | Retrain | 19.71 | Not recorded | 69dc78877d0172140ec78a7b | | DITaR | 19.71 | Not recorded | 69dc78877d0172140ec78a7b | | Retrain | 19.12 | Not recorded | 69dc78877d0172140ec78a7b | | RecEraser | 18.17 | Not recorded | 69dc78877d0172140ec78a7b | | Original | 18.09 | Not recorded | 69dc78877d0172140ec78a7b | | RecEraser | 17.79 | Not recorded | 69dc78877d0172140ec78a7b | | UltraRE | 17.68 | Not recorded | 69dc78877d0172140ec78a7b | | Retrain | 17.35 | Not recorded | 69dc78877d0172140ec78a7b | | DITaR | 17.25 | Not recorded | 69dc78877d0172140ec78a7b | | UltraRE | 17.24 | Not recorded | 69dc78877d0172140ec78a7b | | RecEraser | 16.3 | Not recorded | 69dc78877d0172140ec78a7b | | UltraRE | 15.93 | Not recorded | 69dc78877d0172140ec78a7b | | SISA | 12.32 | Not recorded | 69dc78877d0172140ec78a7b | | SISA | 10.4 | Not recorded | 69dc78877d0172140ec78a7b | | SISA | 10.23 | Not recorded | 69dc78877d0172140ec78a7b | ### Original NDCG@10: 20.36.
