When Good Equations Get Bad Scores: Improving Symbolic Regression Through Better Parameter Optimization
Researchers have developed SAGE-Fit, a new framework designed to improve symbolic regression (SR) by addressing the issue of poor parameter optimization. Existing SR methods often struggle with non-convex inner loops, leading to underestimated scores for correct equations. SAGE-Fit leverages the inherent structural and semantic properties of symbolic expressions to create a more effective fitting process. This plug-and-play module has demonstrated significant improvements in evaluation accuracy and overall performance across various SR systems. AI
