Notes. Precision P, recall R, and F1-score are calculated using the unweighted average of all classes. We also show the weighted F1-score in the F1$\[F_1^{\star}\]$ column. For ‘has-spiral-arms’, we also provide the metrics for finding spiral galaxies in the complete test set (printed in italic), corresponding to the confusion matrix in Fig. 9a.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
