For the evaluation process, the output from your system should be an integer or a float from 0 to 100. This problem can be approached as a classification or regression problem, eitherway the results will be evaluated by fitting a normal distribution with the mean and standard deviation of the votes for each image:
Each prediction is evaluated using the following formula,

In this track, the participants should submit a ZIP file containing only a text file namedPredictions.csv (do not add any folder in the ZIP). Each line should contain a single identifier and the predicted age, separated by a colon, for example:
Predictions.csv: ... image_2519.jpg,18 image_1301.jpg,29 image_4093.jpg,20 ...
