    • Astronomical PSF characterization using grammar evolution and symbolic regression 

      Sarmiento, Ricardo; Baena-Gallé, Roberto; de la Cruz Echeandía, Marina; Ortega de la Puente, Alfonso; Girard, Terrence; Casetti-Dinescu, Dana; Cervantes-Rovira, Alejandro (2024)
      Symbolic regression techniques are promising approaches to learning mathematical models that fit experimental data. One of the most powerful techniques for symbolic regression is Grammatical Evolution (GE). This evolutionary ...

    • Grammar evolution and symbolic regression for astrometric centering of Hubble Space Telescope images 

      Sarmiento, Ricardo; de la Cruz Echeandía, Marina; Ortega de la Puente, Alfonso; Baena-Gallé, Roberto; Girard, Terrence; Casetti-Dinescu, Dana; Cervantes-Rovira, Alejandro (2024)
      Symbolic regression, in general, and genetic models, in particular, are promising approaches to mathematical modeling in astrometry where it is not always clear which is the fittest analytic expression depending on the ...
