New DSCA strategy improves symbolic regression calibration

A new calibration strategy called Dirichlet-Sinkhorn Constant Averaging (DSCA) has been proposed for memetic symbolic regression. This method aims to improve the selection pressure in evolutionary algorithms by evaluating candidate structures across different covariate distributions. DSCA partitions optimization data into subsets with varying covariate distributions, calibrates each candidate independently on these partitions, and then averages the resulting parameters. This approach is shown to enhance functional recovery and the accuracy-complexity trade-off compared to traditional calibration methods like Broyden-Fletcher-Goldfarb-Shanno and Levenberg-Marquardt, particularly under misspecification.

    Coefficient Calibration as Selection Pressure in Symbolic Regression

    arXiv:2610.10931v1 Announce Type: new Abstract: In memetic symbolic regression, candidate structures are compared after coefficient calibration, so the calibration protocol itself contributes to evolutionary selection. Standard centralized calibration evaluates each structure at …
