With ugrizY colors alone, an LSST-like catalog yields at best ~35% contamination and ~19% completeness for globular-cluster candidates; principal components help marginally, autoencoders do not.

The contribution of the color space in LSST-like photometry for the selection of extragalactic globular cluster candidates
With ugrizY colors alone, an LSST-like catalog yields at best ~35% contamination and ~19% completeness for globular-cluster candidates; principal components help marginally, autoencoders do not.
