Resumen:
We classified 170 asteroids based on reflectances obtained in the J-PLUS photometric campaign. The data used were corrected using a genetic algorithm that aimed to correct noise due to rotation. We used Principal Component Analysis and K-MEANS cluster analysis as classification methods. Our classification resulted in twelve groups, with five spectrally close to class S, with a band at 1.0 microns associated with the possible presence of silicates; three to class C, with no absorption characteristics; two to classes V and Q with a very pronounced band to the right of 0.77 microns; one to class K or L; and one to class Ch, with a pronounced band at 0.7 microns, associated with hydration. Since the definition of nomenclature was based on visual inspection comparing the Bus classes, we chose to define a scheme that indicates the two most likely classes. In terms of the heliocentric distribution, we did not find results that differ from previous works
