# Symbolic Regression on Nguyen-F9 Source: [Symbolic Regression on Nguyen-F9]() Collection index: [llms.txt]() Data updated: 2026-02-27T10:34:46.658Z Evaluation of Symbolic Regression performance on the Nguyen-F9 dataset, using R^2 and % Symbolic metrics. 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 | Symbolic Regression | | Dataset (including any stated split) | Nguyen-F9 | | Metric | R^2 | | Unit | SCALAR | | 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 - [R^2](): Higher is better; unit: SCALAR. - [Symbolic Rate](): Higher is better; unit: PERCENT. ## Recorded results | Method | R^2 | Result date | Report paper | | --- | --- | --- | --- | | Baseline KAN | 1 | Not recorded | 6938fe646cfd488761a53ad6 | | Baseline KAN | 1 | Not recorded | 6938fe646cfd488761a53ad6 | | Baseline KAN | 1 | Not recorded | 6938fe646cfd488761a53ad6 | | S2KAN | 0.9999 | Not recorded | 6938fe646cfd488761a53ad6 | | S2KAN | 0.9999 | Not recorded | 6938fe646cfd488761a53ad6 | | S2KAN | 0.9999 | Not recorded | 6938fe646cfd488761a53ad6 | | S2KAN | 0.9992 | Not recorded | 6938fe646cfd488761a53ad6 | | S2KAN | 0.9989 | Not recorded | 6938fe646cfd488761a53ad6 | | S2KAN | 0.9988 | Not recorded | 6938fe646cfd488761a53ad6 | | S2KAN | 0.9987 | Not recorded | 6938fe646cfd488761a53ad6 | | S2KAN | 0.9968 | Not recorded | 6938fe646cfd488761a53ad6 | | S2KAN | 0.9966 | Not recorded | 6938fe646cfd488761a53ad6 | | Baseline KAN | -0.19 | Not recorded | 6938fe646cfd488761a53ad6 | | Baseline KAN | -0.23 | Not recorded | 6938fe646cfd488761a53ad6 | | Baseline KAN | -0.33 | Not recorded | 6938fe646cfd488761a53ad6 | | Baseline KAN | -0.33 | Not recorded | 6938fe646cfd488761a53ad6 | | Baseline KAN | -0.37 | Not recorded | 6938fe646cfd488761a53ad6 | | Baseline KAN | -0.37 | Not recorded | 6938fe646cfd488761a53ad6 | ### Baseline KAN R^2: 1.
