Task 2 - Person Identification
Additionally, you are given the true identity of the users (coded by integer numbers from 1 to 12) for five typing pattern per users in the file task2-keystrokes-12users-train-labels.txt. Each line of this file contains two numbers separated by a comma:
Your task is to recognize the user identities for the rest of the pattern, i.e. for the typing patterns that are not included in task2-keystrokes-12users-train-labels.txt.
SubmissionYour solution for the above task should be a list of pairs. The first number of the pair should be the pattern id. The second number of the pair depends on your prediction, i.e. an integer between 1 and 12 denoting the predicted identity of the user. An example for a file that can be uploaded as submission is task2-random-submission.txt. This file contains all the pattern ids for which predictions are expected, but the predictions (integers between 1 and 12) are filled by a random number generator.
When submitting your solutions, you will need to provide your "login". Please use your nickname as "login". Your solutions will only be displayed at the leaderboard once the administrator has approved your nickname. You may also provide a short description of your solution. Your nickname and the accuracy of your predictions will appear on the leaderboard.
Evaluation of the submissions is based on accuracy. The results reported on the leaderboard are calculated based on a subset of the predictions. In order to ensure the validity of the results, the organizers of the challenge calculate the accuracy on the rest of the predictions as well. Submissions are not displayed on the leaderboard if the accuracy on the both subsets are substantially different.

"Honest Usage" Policy
Finally, we mention that there are many ways of cheating. As this is a machine learning challenge, the intended behaviour is to train a classifier and use it to make predictions. While you are training a classifier, you are expected to use the labelled data as training data in order to fit your model. Any form of cheating or dishonest behaviour is discouraged. If dishonest behaviour is detected, the affected results will be removed from the leaderboard.
