Open-sourced language models generally do not perform well on African languages and are too resource intensive for use on the African context - because they are large, they require GPU compute and have high energy consumption, resources that are not abundant on the African continent. If Africa is to take its place in the AI revolution, we need models that are smaller and smarter and work for our languages.

The Lelapa AI Buzuzu-Mavi Challenge is a challenge to make the SLM released by Lelapa AI (Inkuba LM) smaller and smarter. Participants are able to improve their score by improving the average model performance, by making the model smaller, or by doing both. Improving average model performance involves making the model perform better for one or two languages across one or more tasks. The languages in question are Swahili and Hausa, and the tasks include sentiment analysis, AfriXNLI (true and false) question answering ability, and machine translation from English to the language in question.

The winners of this challenge will produce the world's smallest language models for African languages, models that are both realistic and accessible for local language solutions. A smaller model offers faster inference times on CPUs, making it suitable as a base model that can be fine-tuned for tasks such as sentiment analysis, true/false question answering, and machine translation for Swahili and Hausa. This functionality could enhance the processing and analysis of text-based services, whether in call center operations, educational apps, medical bots, or agricultural assistance in these languages.

The 1st-place winner(s) of this challenge will get the opportunity to co-author a paper with the Lelapa AI team to publish the results of this challenge.

About Lelapa AI (lelapa.ai)

Lelapa AI is a socially-grounded Africa-centric AI research & product lab. We are the leading language AI research and product lab in Africa, building language models for languages that remain under-represented in AI technologies. We are researchers and we are technologists, with an unwavering drive to enable the Africans of now and the future, to thrive digitally, in our own languages.

Each submission file is scored across 2 languages and 3 tasks: sentiment analysis, AfriXNLI true and false question answering ability, and machine translation from English to the language in question.

• Sentiment analysis is scored using F1 Score
• AfriXNLI question and answering is scored using F1 Score
• Machine translation is scored using CHaRacter-level F-score

The scoring script takes these 3 scores and takes a weighted average and this will be your score on the leaderboard.

Your submission file should look like this:

ID              Target

ID_C7AV4GEJP9    1

ID_AFVZYGLXXY    0

The top 20 users on the leaderboard will be requested to submit their inference script, model weights, and number of parameters for the Lelapa team to confirm that your inference script runs and that your reported number of paramesters is correct. Based on your private leaderboard score, combined with the factor of number parameters reduced by will be your final score. The top 5 users will receive an email requesting full code for the Lelapa team to code review. Prizes will go to the top 3 reproducible solutions.

Final score will be calculated by: zindi_score = (PrivateLB_score + (1-(size/PARAM_SIZE))*PrivateLB_score )/2

ENTRY INTO THIS CHALLENGE CONSTITUTES YOUR ACCEPTANCE OF THESE OFFICIAL CHALLENGE RULES.

Full Challenge Rules

This challenge is open to all.

Teams and collaboration

You may participate in challenges 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 challenge, 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 challenge 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 final 5 days of the challenge or 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 challenge.

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 challenge 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 challenge. Automated machine learning tools such as automl are not permitted.

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

You are allowed to access, use and share challenge data for any commercial,. non-commercial, research or education purposes, under a CC-BY SA 4.0 license.

You must notify Zindi immediately upon learning of any unauthorised transmission of or unauthorised access to the challenge 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 10 submissions per day.

You may make a maximum of 200 submissions for this challenge.

Before the end of the challenge 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 challenge, your best public score will be displayed regardless of the submissions you have selected. When the challenge 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 challenge. The Public Leaderboard includes approximately 30% of the test dataset. While the challenge is open, the Public Leaderboard will rank the submitted solutions by the accuracy score they achieve. Upon close of the challenge, the Private Leaderboard, which covers the other 70% of the test dataset, will be made public and will constitute the final ranking for the challenge.

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 resource restrictions are indicated on the challenge page you must adhere to them.

If you are in the top 10 at the time the leaderboard closes, we will email you to request your code. On receipt of email, you will have 48 hours to respond and submit your code following the Reproducibility of submitted code guidelines detailed below. Failure to respond will result in disqualification.

If your solution places 1st, 2nd, or 3rd on the final leaderboard, 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).

The winners will be paid via bank transfer, PayPal if payment is less than or equivalent to $100, 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 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 challenge. If your account cannot receive US Dollars or the currency of the challenge then your bank will need to provide proof of this and Zindi will try to accommodate this.

Please note that due to the ongoing Russia-Ukraine conflict, we are not currently able to make prize payments to winners located in Russia. We apologise for any inconvenience that may cause, and will handle any issues that arise on a case-by-case basis.

Payment will be made after code review and sealing the leaderboard.
