Yassine Koubaa
Nationality: Tunisian
Host: Artelys
| Background: Yassine is a graduate engineer from Ecole Polytechnique de Tunisie, where he specialized in Complex Systems. He began my academic journey with a rank of 28th in the national engineering entrance exam in Tunisia. At Ecole Polytechnique de Tunisie, he studied a broad range of subjects, including Stochastic Processes, Optimization, Microeconomics, Theory of Signals and Systems, Continuous Mechanics, and High-Performance Computing. His practical experience was enriched through an internship at ReDX Technologies, where he focused on optimizing seismic kernels across multiple GPUs. This role provided him with hands-on experience in performance evaluation and enhancement. |
| Master’s Thesis: Enhancing Low-Rank Updates Performance for Sparse Direct Solvers For his master’s thesis at École Normale Supérieure de Lyon, France, he worked on enhancing low-rank updates performance for sparse direct solvers. He developed methods to improve the update process, including accumulating updates before compression, compressing multiple blocks into a single representation, and integrating the accumulation and compression process using a tree-based method. These advancements led to reduced memory usage and lower computational costs, enhancing the overall performance of sparse direct solvers. |
| Research Interests: His research interests center on applying mathematics to solve real-world problems. He focuses on tensor computations, large-scale optimization, and parallel computing, aiming to develop practical solutions and advance current methods in these fields. |
| Research Goals: In his PhD research, he seeks to further these interests by developing algorithms for efficient low-rank tensor decompositions and enhancing optimization techniques with tensor-based models. His goal is to create new methods for handling high-dimensional optimization problems and improving performance through innovative approaches. |
| Hobbies: Outside of his research, he enjoys hiking, playing football, reading, and travelling. These activities help him maintain a balanced and fulfilling life. |
