When Good Equations Get Bad Scores: Improving Symbolic Regression Through Better Parameter Optimization
arXiv:2605.23272v1 Announce Type: new Abstract: Symbolic Regression (SR) plays a central role in scientific knowledge discovery by distilling mathematical equations from observational data. Most existing SR methods function within a bi-level optimization framework: an outer loop that searches for the discrete equation structure, and an inner loop that optimizes the continuous parameters of that structure. Crucially, parameter-fitting quality directly determines a structure's score and thus the outer-loop search. However, nonlinear operators make the inner loop highly non-convex, and budget-dri
This research addresses a fundamental bottleneck in symbolic regression, which is gaining renewed interest as AI systems seek more interpretable and robust solutions for scientific discovery.
Improved symbolic regression directly enhances AI's capability for automated scientific theory generation, accelerating discovery in various fields from physics to biology.
The ability to more accurately evaluate potential equations will lead to faster identification of fundamental laws and relationships within complex datasets, making AI more effective in scientific modeling.
