When Community Leads: Rwanda to Host the 2025 Annual Deep Learning Indaba

by siobhan | Aug 8, 2025 | Sauti Yetu

Pierrette Mahoro Mastel currently works at GIZ as a Digital Health Advisor, prior to that she was at CMU-Africa where she did her Masters in IT with a major in Machine Learning. Mastel is the IndabaX Rwanda lead and one of the 2025 General Chairs for the Indaba to be held in Kigali 17-22 August 2025. 

I first attended the Annual Deep Learning Indaba in 2022 with two of my other CMU Africa colleagues. I still remember several people’s surprised faces when I would say that I’m from Rwanda. I kept asking why and they all said the same thing; it was their first time meeting a Rwandan at the Indaba. There was one other Rwandan from University of Oxford that year, and those who knew him made sure to introduce us. Honestly, it was a little embarrassing. Here I was at the largest gathering of AI practitioners on the continent—and yet Rwandan representation was virtually nonexistent. I felt inspired to change that.

Rwanda’s AI/ML community began taking shape around 2018-2019 when African Institute of Mathematical Sciences Rwanda (AIMS) students organised the first IndabaX Rwanda in 2019. Around the same time, CMU-Africa alum launched AI Saturdays Kigali. However, these early efforts lost momentum when the AI Saturdays founder left the country, and the COVID-19 pandemic brought IndabaX Rwanda to a halt. The community started gaining traction again with the creation of MBAZA NLP in 2021.

Towards the end of the 2022 Indaba, I was then asked by one of the Indaba organisers to reinitiate IndabaX Rwanda. We held our first IndabaX the following year, which was co-located with ICLR and we had over 100 attendees. Most were international participants already in Kigali for ICLR, rather than members of our local community—but it was a start.

With the presence of CMU-Africa, AI Saturdays Kigali, the growth of Mbaza NLP, and eventually the establishment of IndabaX Rwanda, the machine learning and AI community in Rwanda steadily began to grow. That growth was clearly visible in 2023—from just me attending the Indaba in 2022, to six Rwandans and more than ten others from our local community participating the following year.

In 2024, we hosted a two-day IndabaX Rwanda that drew over 150 attendees. What excited me most wasn’t just the increase in numbers, but the quality of the research, the projects, the conversations being showcased. The maturity was quite apparent. Fast forward to 2025, Rwanda is hosting the Annual Deep Learning Indaba. And while grassroots communities alone didn’t get us here, they laid much of the foundation. Rwanda’s progressive visa policies and its strong Meetings,Incentives, Conferences and Exhibitions (MICE) sector also played a critical role in making this possible.

It’s no surprise that grassroots organisations such as Mbaza NLP, the Deep Learning Indaba, Masakhane, and Data Science Africa have played and continue to play a major role in shaping Africa’s local AI/ML ecosystems. For over a decade, these communities have been at the forefront of ensuring that Africans are not just bystanders or consumers in the global AI movement, but active contributors, researchers, and builders. While many governments are only now beginning to draft their National AI Strategies, these communities have already laid the groundwork. And while it's encouraging to see countries across Africa taking serious steps towards advancing AI—drafting national strategies, setting policies, and organising high-level events such as the Global AI Summit on Africa to fund AI efforts on the continent — my hope is that we don’t take as long to recognise who is best positioned to implement these strategies. Grassroots organisations should be at the forefront for funding and support. They have a proven track record: building talent pipelines, driving community-led research, and creating inclusive platforms for African voices in AI. If we want these national strategies to translate into real, sustainable impact, then the implementers must be those who have already shown they can do the work—and have been doing it long before it was on anyone’s policy agenda.

Wangari Maathai Impact Award

The Wangari Maathai Impact Award recognises and celebrates work by African innovators, thinkers, and advocates who demonstrate impactful work, including, but not limited to, technical, societal, environmental, and economic domains, around machine learning and artificial intelligence. This award reinforces the legacy of Wangari Maathai by acknowledging the capacity of individuals to be a positive force for change: by recognising ideas and initiatives that demonstrate that each of us, no matter how small, can make a difference.

The DLI 2026 Wangari Maathai Impact Award is awarded to:

Winner: Dr Hellina Hailu Nigatu

Country: Ethiopia

Affiliation: Artificial Intelligence Accountability Lab (AIAL) at Trinity College Dublin

Essence of the Award: Dr Hellina Hailu Nigatu says that having read Wangari Maathai's autobiography, Unbowed, it is a personal privilege to be recognized with an award in her name. She wants to give gratitude to her mentees on the project who carried the majority of the work. This recognition is as much, if not more, a fruit of their effort and hard work. She hopes this will also inspire more grassroots ventures in the African AI landscape that foster meaningful community engagement and participation.

Dr Hellina Hailu Nigatu is recognised for her work addressing gender bias in machine translation across three Ethiopian languages: Amharic, Afan Oromo, and Tigrinya. Rather than adapting English benchmarks, she built evaluation frameworks and datasets directly within African languages, preserving cultural nuances that translation from English cannot capture. Key to this work is the Yeswa Stories dataset, centered on African women's narratives and lived experiences. Seven Ethiopian female students participated as paid researchers, benefiting from funding, compute access, and substantive mentorship throughout. The project produced open-release benchmark datasets now available to the broader African NLP community. Her mentorship has been described by those she supervised as transformative, not nominal.

Runner-up: Abdel-aziz Harane Abounounou 

Country: Chad

Affiliation: Chad AI Network

Essence of the Award: Abdel-aziz Harane says that he is deeply honored by this award. This recognition reflects his constant obsession: solving Chad's real problems through AI and software engineering. It renews his commitment to the Chad AI Network's mission of sustainable, locally driven transformation.

Abdel-aziz Harane Abounounou is recognised for his work building the first natural language processing tools for Chad's indigenous languages, a country with 123 languages yet only two represented in existing digital tools. Rather than waiting for a foreign lab to take interest, he set out to build the entire pipeline himself, working directly with the communities who speak these languages. The Kalam-na project anchors this work, collecting audio and text data across 16 dialects of the Sara language family. Native speakers contribute their own voices through Kalam-na Voice, a platform built to remove technical barriers to participation. The project has gathered over 68,000 transcribed audio clips and 72,000 aligned texts, laying the groundwork for open ASR, TTS, and MT models. He also founded the Chad AI Network, now over 200 members strong, and ran two editions of IndabaX Chad. This work reaches an estimated 4 million speakers of Chadian languages currently shut out of the digital world.

Thamsanqa Kambule Doctoral Award

The Thamsanqa Kambule Doctoral Award recognises, encourages, and celebrates excellence in research and writing by doctoral candidates at African universities in any area of computational and statistical sciences. Its recipients are those who uphold Thamsanqa Kambule’s legacy as a defender of learning, a seeker of knowledge, and an activist for equality.

The DLI 2026 Thamsanqa Kambule Doctoral Award is awarded to:

Winner: Dr Everlyn Chimoto 

Country: Kenya

Affiliation: Lelapa AI & Riara University

Essence of the Award: “Receiving this award is deeply meaningful because it recognises not only the years of work invested in this thesis, but also the support of my supervisor, collaborators, family, and the African NLP community that has continually inspired and challenged me. To me, it also recognises the importance of pursuing research motivated by the needs of underrepresented language communities. I believe this work demonstrates that data-centric approaches can make meaningful progress in low-resource settings while remaining relevant to many other machine learning problems. I am encouraged to continue pursuing research that advances knowledge while creating opportunities for more languages and more people to participate in language technology,” says Dr Everlyn Chimoto.

Dr Everlyn Chimoto is recognised for a doctoral thesis on sentence alignment for the Marama dialect of Luhya, CAT data pruning which achieves 92% of full-data performance at 50% of the data with no additional compute cost, GrammaMT which delivers over 12 BLEU point improvements for endangered languages from as few as 21 grammatical examples, and COMET-QE active learning for efficient data selection. Together these form a framework immediately usable by African NLP practitioners working under real compute and data constraints. Her work is centred on improving model performance to make AI systems more inclusive for African language communities.

The DLI 2026 Thamsanqa Kambule Doctoral Award runner-up is:

Runner-up: Dr Devon Jarvis 

Country: South Africa

Affiliation: University of the Witwatersrand

Essence of the Award: “I started learning ML while volunteering at the Indaba in 2017. To be recognised nine years later is gratifying and reflects the impact this community has had on my career,” says Dr Devon Jarvis.

Dr Devon Jarvis is recognised for his doctoral work developing a theoretical framework for controlled semantic cognition using deep and nonlinear neural networks to explain how the human brain flexibly applies learned semantic concepts to new contexts. Rather than treating machine learning purely as an engineering tool, he built tractable theoretical models that shed light on the principles of human cognition itself. His dissertation extends deep linear network theory to explain systematic generalisation, introduces a novel framework (the Rectified Linear Network) to model ReLU network training dynamics, and shows that these networks can capture all six classical properties of controlled semantic cognition while still falling short of systematic generalisation. He then proposes a meta-learning model, the Meta-GDLN, as a path toward closing that gap. He has since remained on the continent to establish the CAandL Lab, one of Africa's first computational neuroscience labs.

Grace Alele-Williams Masters Award

The Grace Alele-Williams Masters Award recognises and celebrates excellence in research and writing by master's candidates at African universities in any area of computational and statistical sciences. Its recipients are those who uphold Grace Alele-Williams’ legacy as a defender of learning, champion of academic excellence, and activist for access to education.

The DLI 2026 Grace Alele-Williams Masters Award is awarded to:

Winner: Akinbobola Adegboyega

Country: Nigeria

Affiliation: Olabisi Onabanjo University

Essence of the Award: According to Akinbobola Adegboyega, “The Alele-Williams Award is a reminder that hard work, curiosity, and dedication matter, and it inspires me to keep making meaningful contributions for societal benefit.”

Akinbobola Adegboyega is recognised for a Master's thesis that introduces affective fidelity as a new evaluation lens for machine translation in low-resource tonal languages, reframing emotion as a core measure of translation faithfulness rather than a secondary concern. His work targets Yorùbá, a language representing just 0.008% of Common Crawl training data. He produced a culturally validated bilingual emotion dataset of over 200 annotated paragraph pairs verified by native speakers, created a reproducible benchmarking framework evaluating four major language models, and identified six distinct failure modes specific to tonal low-resource language translation. The dataset has been released openly, contributing usable infrastructure to the African NLP community.
