This is a private hackathon open to Cameroonians students. If you are a student in Cameroonian and would like to participate, contact Alex Kamenia.

The Tunisian Company of Electricity and Gas (STEG) is a public and a non-administrative company, it is responsible for delivering electricity and gas across Tunisia. The company suffered tremendous losses in the order of 200 million Tunisian Dinars due to fraudulent manipulations of meters by consumers.

Several other companies as well as the Tunisian Company of Electricity and Gas suffer from this scourge which is very detrimental to their activities. The objective at this level is to propose methods of determining fraudulent customers from the history of their consumption.

We will also rank solutions according to their tidiness. This will be reflected by a subjective score based on the following criteria: reproducibility, readability, creativity.

Teams and collaboration

You may participate in this competition as an individual or in a team of up to four people. When creating a team, the team must have a total submission count less than or equal to the maximum allowable submissions as of the formation date. A team will be allowed the maximum number of submissions for the competition, minus the highest number of submissions among team members at team formation. Prizes are transferred only to the individual players or to the team leader.

Multiple accounts per user are not permitted, and neither is collaboration or membership across multiple teams. Individuals and their submissions originating from multiple accounts will be disqualified.

Code must not be shared privately outside of a team. Any code that is shared, must be made available to all competition participants through the platform. (i.e. on the discussion boards).

Datasets and packages

The solution must use publicly-available, open-source packages only. Your models should not use any of the metadata provided.

You may use only the datasets provided for this competition. Automated machine learning tools such as automl are not permitted.

You may use pretrained models as long as they are openly available to everyone.

The data used in this competition is the sole property of Zindi and the competition host. You may not transmit, duplicate, publish, redistribute or otherwise provide or make available any competition data to any party not participating in the Competition (this includes uploading the data to any public site such as Kaggle or GitHub). You may upload, store and work with the data on any cloud platform such as Google Colab, AWS or similar, as long as 1) the data remains private and 2) doing so does not contravene Zindi’s rules of use.

You must notify Zindi immediately upon learning of any unauthorised transmission of or unauthorised access to the competition data, and work with Zindi to rectify any unauthorised transmission or access.

Your solution must not infringe the rights of any third party and you must be legally entitled to assign ownership of all rights of copyright in and to the winning solution code to Zindi.

Submissions and winning

You may make a maximum of 20 submissions per day. Your highest-scoring solution on the private leaderboard at the end of the competition will be the one by which you are judged.

You may only make 40 submissions over the whole competition.

Your solution needs to be innovative and show signs of creative thinking. To mimic a real Zindi challenge, solutions need to be unique in order for them to be useful to a client. Keep this in mind when creating your solutions.

If your solution places 1st, 2nd, or 3rd in the final ranking, you will be required to submit your winning solution code to us for verification and you thereby agree to share your code on GitHub as a public good to the sector. We also encourage all participants to share their solutions on GitHub.

Ambassador Allassan Tchangmena A Nken will reach out to the winners via the Zindi inbox. You will have 24 hours from the direct message to submit your code for review. Zindi reserves the right to disqualify any user, team if the code does not reproduce the winning submission.

Zindi maintains a public leaderboard and a private leaderboard for each competition. The Public Leaderboard includes approximately 50% of the test dataset. While the competition is open, the Public Leaderboard will rank the submitted solutions by the accuracy score they achieve. Upon close of the competition, the Private Leaderboard, which covers the other 50% of the test dataset, will be made public and will constitute the final ranking for the competition.

If two solutions earn identical scores on the leaderboard, the tiebreaker will be the date and time in which the submission was made (the earlier solution will win).

You acknowledge and agree that Zindi may, without any obligation to do so, remove or disqualify an individual, team, or account if Zindi believes that such individual, team, or account is in violation of these rules. Entry into this competition constitutes your acceptance of these official competition rules.

Please refer to the FAQs and Terms of Use for additional rules that may apply to this competition. We reserve the right to update these rules at any time.

The metric used for this challenge is F1.

Then the submission file should be as follows:

client_id       target
test_Client_0     1
test_Client_1     1
test_Client_10    0

F1 is a measure of a test's accuracy. It is calculated from the precision and recall of the test, where the precision is the number of correctly identified positive results divided by the number of all positive results, including those not identified correctly, and the recall is the number of correctly identified positive results divided by the number of all samples that should have been identified as positive.

1st Place: 50 000 Franc CFA

2nd Place: 40 000 Franc CFA

3rd Place: 25 000 Franc CFA

4th Place: 15 000 Franc CFA

5th Place: 10 000 Franc CFA

Competition closes on 21 February 2020.

Final submissions must be received by 10:59 PM GMT.

The private leaderboard will be revealed 10:59PM GMT.
