GeneticKNN:a weighted KNN approach supported by genetic algorithm for photometric redshift estimatio
We combine K-nearest neighbors(KNN)with a genetic algorithm(GA)for photometric redshift estimation of quasars,short for ......
Based on the SDSS and SDSS-WISE quasar datasets, we put forward two schemes to estimate the photometric redshifts of qua......
