... We present a new technique to segregate old and young stellar populations in galactic spectra using machine learning methods. We used an ensemble of classifiers, each classifier in the ensemble specializes in young or old populations and was trained with locally weighted regression and tested using ten-fold cross-validation. ... In this work we propose a Machine Learning (ML) method to determine the age of stellar populations in synthetic galactic spectra. ... Combine results in an ensemble. ...
