Prepare for UmojaHack by
Short-term insurance claims are one of the largest costs in the insurance industry, and are extremely difficult to forecast. Zimnat Insurance wants to predict the value of future claims per client, in order to better forecast annual costs.
The objective of this challenge is to create a machine learning model to predict how much a client will claim from Zimnat per month for a whole year.
The solution will aid Zimnat in being better prepared to address claims that are submitted, and improve customer satisfaction by alerting clients to possible claims they will make in the future.
Watch this video for a walk-through of the starter notebook and for interesting insights.
About Zimnat (zimnat.co.zw)
Zimnat has been a leading player in the Zimbabwean life assurance and short-term insurance industries since 1946. For over 70 years, Zimnat has been protecting the assets of Zimbabweans, managing their wealth and ensuring that their assets and funds are passed onto future generations, should that be their wish.
The error metric for this competition is the Mean Absolute Error.
For every row in the dataset, submission files should contain 2 columns: claim_id and target.
Your submission file should look like this:
ID_9Y2BPMK5PNZC 49.45 ID_7KXKRHSALDFG 1094.00 ID_TDH08G5G5IV8 3714.36
1st prize: $1000
2nd prize: $800
3rd prize: $600
PLEASE NOTE that Zindi will only award ONE PRIZE PER UNIVERSITY; in other words, if more than one individual or team from a specific university would be eligible to win a prize, we will award a prize to the higher-ranked individual or team only.
Country prize: $100 (given to the highest ranking user/team from a specific country that didn’t win any other prize). Country winners will be determined by competition ranking relative to the number of users on the leaderboard, adjusted by a factor. Your percentage placement will be multiplied by 3 (advanced challenge), 2.4 (intermediate challenge) or 1.8 (beginner challenge.) The user with the highest adjusted score will be the country winner.

Key times to note:
Teams and collaboration
You may participate in competitions 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 total 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 immediately disqualified from the platform.
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).
The Zindi data scientist who sets up a team is the default Team Leader but they can transfer leadership to another data scientist on the team. The Team Leader can invite other data scientists to their team. Invited data scientists can accept or reject invitations. Until a second data scientist accepts an invitation to join a team, the data scientist who initiated a team remains an individual on the leaderboard. No additional members may be added to teams within the last hour of a hackathon.
The team leader can initiate a merge with another team. Only the team leader of the second team can accept the invite. The default team leader is the leader from the team who initiated the invite. Teams can only merge if the total number of members is less than or equal to the maximum team size of the competition.
A team can be disbanded if it has not yet made a submission. Once a submission is made individual members cannot leave the team.
All members in the team receive points associated with their ranking in the competition and there is no split or division of the points between team members.
Datasets and packages
The solution must use publicly-available, open-source packages only.
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 75 submissions per day.
You may make a maximum of 150 submissions for this competition.
Before the end of the competition you need to choose 2 submissions to be judged on for the private leaderboard. If you do not make a selection your 2 best public leaderboard submissions will be used to score on the private leaderboard.
During the competition, your best public score will be displayed regardless of the submissions you have selected. When the competition closes your best private score out of the 2 selected submissions will be displayed.
Zindi maintains a public leaderboard and a private leaderboard for each competition. The Public Leaderboard includes approximately 20% 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 80% of the test dataset, will be made public and will constitute the final ranking for the competition.
Note that to count, your submission must first pass processing. If your submission fails during the processing step, it will not be counted and not receive a score; nor will it count against your daily submission limit. If you encounter problems with your submission file, your best course of action is to ask for advice on the Competition’s discussion forum.
If you are in the top 5 at the time the leaderboard closes, we will email you to request your code. On receipt of email, you will have 2 hours to respond and submit your code following the submission guidelines detailed below. Failure to respond will result in disqualification.
If your solution places is one of the prize winning solutions, you will be required to submit your winning solution code to us for verification, and you thereby agree to assign all worldwide rights of copyright in and to such winning solution to Zindi.
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).
If the error metric requires probabilities to be submitted, do not set thresholds (or round your probabilities) to improve your place on the leaderboard. In order to ensure that the client receives the best solution Zindi will need the raw probabilities. This will allow the clients to set thresholds to their own needs.
The winners will be paid via bank transfer, PayPal, or other international money transfer platform. International transfer fees will be deducted from the total prize amount, unless the prize money is under $500, in which case the international transfer fees will be covered by Zindi. In all cases, the winners are responsible for any other fees applied by their own bank or other institution for receiving the prize money. All taxes imposed on prizes are the sole responsibility of the winners. The top 3 winners or team leaders will be required to present Zindi with proof of identification, proof of residence and a letter from your bank confirming your banking details.Winners will be paid in USD or the currency of the competition. If your account cannot receive US Dollars or the currency of the competition then your bank will need to provide proof of this and Zindi will try to accommodate this.
Payment will be made after code review and an introductory call with the host.
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.
Zindi is committed to providing solutions of value to our clients and partners. To this end, we reserve the right to disqualify your submission on the grounds of usability or value. This includes but is not limited to the use of data leaks or any other practices that we deem to compromise the inherent value of your solution.
Zindi also reserves the right to disqualify you and/or your submissions from any competition if we believe that you violated the rules or violated the spirit of the competition or the platform in any other way. The disqualifications are irrespective of your position on the leaderboard and completely at the discretion of Zindi.
Important Note: By entering this hackathon you acknowledge that Zindi reserves the right to disqualify winning teams before, during, and after the competition. Code review will take place after the winners have been announced but before prize money has been paid; if upon reviewing the winning code, it shows that the winning team did not follow competition rules in any way whatsoever, Zindi may disqualify the team and their university. This disqualification and the reasons for it will be made public, and the disqualified team will not be eligible for receiving the prizes, regardless of any earlier prize announcements. Zindi reserves the right to revoke prizes at any stage if there is evidence of teams or universities breaking any competition rules or otherwise behaving in a way that brings Zindi into disrepute. In this case, the prizes will be awarded to the next highest-ranked eligible team and university. All decisions made by Zindi are final.
