Submissions are scored based on their accuracy of predicting which of the seven classes should be assigned to each image . During the contest, the current test.csv file will be used to provide a public leaderboard. Because this task is very easy for humans to do, we will not provide the final test inputs until 72 hours before the contest closes. After we provide the final test inputs, teams wishing to be scored for the final competition should run their classifier on the new data and upload a new .csv file before the competition closes. This procedure is intended to discourage manual labeling of test data.
