**Question:** Are you going to release more subjects for the training set? The current training set is too small to be meaningful. The number of cases is very small and the total number of subjects is very small compared with the whole data set. **Answer:** If ?release? means ?make public?, the answer is no. We are only authorized to release 500 mammography images (Pilot Set). However the training set in the Leaderboard Phase will contain data from about 43k subjects. More data will be made available during the Final Round in the Evaluation Phase (for a total of about 60k subjects).
