# Collaborative Filtering on MovieLens 100k Source: [Collaborative Filtering on MovieLens 100k]() Collection index: [llms.txt]() Data updated: 2026-06-05T07:00:36.111Z Evaluation of Collaborative Filtering performance on the MovieLens 100k dataset, measured by the percentage of correctly reconstructed unobserved data. 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 | Collaborative filtering | | Dataset (including any stated split) | MovieLens 100k | | Metric | Reconstruction Accuracy | | 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 - [Reconstruction Accuracy](): Higher is better; unit: PERCENT. ## Recorded results | Method | Reconstruction Accuracy | Result date | Report paper | | --- | --- | --- | --- | | MULTI LAYER ORM | 70.1 | Not recorded | 68fa53ae1e209131ce98551e | | ORM | 70 | Not recorded | 68fa53ae1e209131ce98551e | | MP | 69.5 | Not recorded | 68fa53ae1e209131ce98551e | | ORM | 68.9 | Not recorded | 68fa53ae1e209131ce98551e | | MULTI LAYER ORM | 68.8 | Not recorded | 68fa53ae1e209131ce98551e | | MP | 67.5 | Not recorded | 68fa53ae1e209131ce98551e | | MULTI LAYER ORM | 66.5 | Not recorded | 68fa53ae1e209131ce98551e | | ORM | 66.4 | Not recorded | 68fa53ae1e209131ce98551e | | MP | 65.2 | Not recorded | 68fa53ae1e209131ce98551e | | MULTI LAYER ORM | 65.2 | Not recorded | 68fa53ae1e209131ce98551e | | ORM | 64.9 | Not recorded | 68fa53ae1e209131ce98551e | | ORM | 63.5 | Not recorded | 68fa53ae1e209131ce98551e | | MULTI LAYER ORM | 63.5 | Not recorded | 68fa53ae1e209131ce98551e | | MP | 63 | Not recorded | 68fa53ae1e209131ce98551e | | MP | 60.7 | Not recorded | 68fa53ae1e209131ce98551e | | ORM | 58.5 | Not recorded | 68fa53ae1e209131ce98551e | | MULTI LAYER ORM | 58.5 | Not recorded | 68fa53ae1e209131ce98551e | | MP | 52.8 | Not recorded | 68fa53ae1e209131ce98551e | ### MULTI LAYER ORM Reconstruction Accuracy: 70.1.
