# Length of Stay Prediction (LOS) on MIMIC-IV (Mutual Information) Source: [Length of Stay Prediction (LOS) on MIMIC-IV (Mutual Information)]() Collection index: [llms.txt]() Data updated: 2026-06-17T07:01:19.448Z Evaluation of models predicting patient Length of Stay (LOS) using the MIMIC-IV clinical database, specifically measured using Mutual Information (MI). 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 | Length of stay prediction (LOS) | | Dataset (including any stated split) | MIMIC-IV | | Metric | Mutual Information (MI) | | Unit | SCALAR | | Direction | Higher 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 - [Mutual Information (MI)](): Higher is better; unit: SCALAR. ## Recorded results | Method | Mutual Information (MI) | Result date | Report paper | | --- | --- | --- | --- | | MLCI | 0.1542 | Not recorded | 6a322a39d33dfb23e783ec5b | | DeepSets | 0.1536 | Not recorded | 6a322a39d33dfb23e783ec5b | | Set Transformer | 0.1516 | Not recorded | 6a322a39d33dfb23e783ec5b | | Pure MIL Attention Pooling | 0.1493 | Not recorded | 6a322a39d33dfb23e783ec5b | | Star-GAT | 0.1489 | Not recorded | 6a322a39d33dfb23e783ec5b | | Gradient Boosted Trees | 0.1486 | Not recorded | 6a322a39d33dfb23e783ec5b | | Deep MLP Bag-of-Codes | 0.1473 | Not recorded | 6a322a39d33dfb23e783ec5b | | Deep and Cross Network | 0.1448 | Not recorded | 6a322a39d33dfb23e783ec5b | | Factorization Machine | 0.1388 | Not recorded | 6a322a39d33dfb23e783ec5b | | FusedLogits LR | 0.1375 | Not recorded | 6a322a39d33dfb23e783ec5b | | kNN | 0.0843 | Not recorded | 6a322a39d33dfb23e783ec5b | | Multinomial Naive Bayes | 0.079 | Not recorded | 6a322a39d33dfb23e783ec5b | | Complement Naive Bayes | 0.0775 | Not recorded | 6a322a39d33dfb23e783ec5b | | CCI+ECI | 0.0639 | Not recorded | 6a322a39d33dfb23e783ec5b | | Elixhauser | 0.0626 | Not recorded | 6a322a39d33dfb23e783ec5b | | Charlson | 0.0341 | Not recorded | 6a322a39d33dfb23e783ec5b | ### MLCI Mutual Information (MI): 0.1542.
