Table 2.
A qualitative comparison of the three fitting approaches—Symbolic Regression, Bassler model and Renormalization model, as inferred from our results.
| SR fitting | Accuracy and interpretability, but no generality. Considers non-linear terms |
| Bassler model | Physics-based fitting, but material- and range-specific. Not accurate beyond the bounds selected above, so not general |
| Renormalization fitting | General and interpretable approach but requires rescaling depending on the physics at play. Reconstruction is less accurate compared to Bassler and SR |
