Completeness of DSC Combmod. Predicted labels are obtained from the class with the largest posterior probability using the global prior. (a) Variation of completeness with magnitude and absolute Galactic latitude for each of the three classes using the original validation data set. (b) As (a), but using the cleaned validation set (i.e. after removal of the Magellanic Clouds and mislabelled sources). (c) Completeness as a function of absolute Galactic latitude for three brightness ranges (columns) for each class (rows). In each panel the dashed line shows the performance on the original validation data set and the solid line the cleaned validation data set. These one-dimensional plots are essentially a marginalisation of the 2D representations in panels a and b but weighting by the number of sources in each bin. The curves have been smoothed with a Gaussian filter to remove noise. The shaded region encompasses the LMC at | sin b| = −0.54 and the SMC | sin b| = −0.70 (which are excluded from the cleaned set).
