How to validation??? We don't have a dataset, should we submit our code???Posted by: xjSJTU @ Sept. 26, 2016, 1:50 p.m.
During Phase 2, you are supposed to submit the predictions of the best model according to Phase 1 on a new hold-out dataset (we allow for 3 attempts just in case you submit the wrong file and want to redo it). The score will be visible on the leaderboard. We will use the score shown on the leaderboard to make the final winner selection.Posted by: spirinus @ Sept. 30, 2016, 1:44 p.m.
