About Me
I'm Jérémie Mabiala. I studied mathematics and somewhere along the way got curious about what machines can learn.
I'm an MSc student in the African Master in Machine Intelligence (AMMI) program at AIMS Senegal. Before that, I did a Master's in Mathematical Sciences at Stellenbosch University & AIMS South Africa. Still learning — ML theory, NLP, computer vision, LLMs, and optimization interest me most, but I'm open to almost anything AI & math-related.
Before this, I ran practical sessions at the Department of Mathematics and Computer Science, University of Kinshasa. I now help run Python, PyTorch, and Machine Learning bootcamps at AIMS Senegal — teaching remains one of the best ways I know to actually understand something.
Outside of that, I freelance in software development, and I read novels.

Did you know? A linear SVM classifier is really just a hyperplane splitting your text vectors — and the margin is exactly a distance formula in disguise.
