# Operator Learning on MFC rho-parameter family (OOD) Source: [Operator Learning on MFC rho-parameter family (OOD)]() Collection index: [llms.txt]() Data updated: 2026-06-11T11:26:57.407Z Evaluation of Operator Learning models on the MFC rho-parameter family dataset under Out-of-Distribution (OOD) conditions, typically measured using Mean relative L2 error. 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 | Operator Learning | | Dataset (including any stated split) | MFC rho-parameter family (OOD) | | Metric | Mean Relative L2 Error | | Unit | SCALAR | | Direction | Lower is better | | Results loaded | 12 of 12 | | 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 - [Mean Relative L2 Error](): Lower is better; unit: SCALAR. - [Reduction (%)](): Higher is better; unit: PERCENT. ## Recorded results | Method | Mean Relative L2 Error | Result date | Report paper | | --- | --- | --- | --- | | Raw ICON | 0.004 | Not recorded | 6a2a4153d33dfb23e783958d | | CHOP | 0.004 | Not recorded | 6a2a4153d33dfb23e783958d | | Raw ICON | 0.0046 | Not recorded | 6a2a4153d33dfb23e783958d | | CHOP | 0.0046 | Not recorded | 6a2a4153d33dfb23e783958d | | Raw ICON | 0.0046 | Not recorded | 6a2a4153d33dfb23e783958d | | CHOP | 0.0046 | Not recorded | 6a2a4153d33dfb23e783958d | | Raw ICON | 0.07 | Not recorded | 6a2a4153d33dfb23e783958d | | CHOP | 0.07 | Not recorded | 6a2a4153d33dfb23e783958d | | Raw ICON | 0.0747 | Not recorded | 6a2a4153d33dfb23e783958d | | CHOP | 0.0754 | Not recorded | 6a2a4153d33dfb23e783958d | | Raw ICON | 0.0795 | Not recorded | 6a2a4153d33dfb23e783958d | | CHOP | 0.0809 | Not recorded | 6a2a4153d33dfb23e783958d | ### Raw ICON Mean Relative L2 Error: 0.004.
