Local outlier factor vs the variance of the G band folded light curve decoder (${\sigma }_F^2$) for the 7431 sources from the RR Lyr SOS table within the test partition. A large LOF indicates that the source is isolated in the latent space. A large ${\sigma }_F^2$ is associated with a noisy reconstruction of the folded light curve. Black stars show the three sources with the largest LOF, while black diamonds show the three sources with the largest ${\sigma }_F^2$.
