Ahcène Boubekki

about me

I am a postdoctoral researcher at the Machine Learning and Uncertainty group at Physikalisch-Technische Bundesanstalt (Berlin).

Prior to joining the PTB, I was a postdoctoral researcher at the Machine Learning group at University in Tromsø (Norway).

I did my PhD at the Machine Learning Group under te supervision of Ulf Brefeld at the Leuphana University of Lüneburg.

I received a Master and a Bachelor in pure Mathematics from the University Pierre et Marie Curie, Paris 6, now aka Sorbonne Université🤷.

research interests

I am interested in explainable ai, unsupervised learning, representation learning, generative models, probabilistic models, user modeling and understanding, education data mining.
