Definition
Symbolic regression is a type of regression analysis that seeks to find a mathematical expression, typically represented as a tree structure, that optimally fits observed data. Unlike traditional regression which assumes a fixed functional form, symbolic regression evolves both the structure and parameters of the equation. It is particularly valuable in scientific discovery because it produces human-readable models, offering insights into underlying physical or biological laws rather than just predictive accuracy.
Summary
Symbolic regression is a technique that searches for mathematical expressions that best fit a dataset, aiming to discover interpretable formulas.
