My work focuses on training large-scale self-supervised vision models for histopathology (mostly tweaking Dinov2 training), aiming to improve cancer and rare disease diagnostics ( or at least the numbers in the benchmarks 🙃 ).\n\nMy expertise lies in deep learning for vision and language, with a strong interest in continual learning and representation learning for robust generalization and efficient scaling.\n\nPreviously, I conducted postdoctoral research at [UdeM](https://www.umontreal.ca/), [Mila – Quebec Artificial Intelligence Institute](https://mila.quebec/en/) under the supervision of [Irina Rish](https://mila.quebec/en/person/irina-rish/), where I worked on large-scale continual [pretraining of LLMs](https://arxiv.org/abs/2308.04014) (large language models).\n\nI earned my PhD in Computer Science from [IP Paris - Institut Polytechnique de Paris](https://www.ip-paris.fr/en) (France) in the [U2IS lab](http://u2is.ensta-paris.fr/) under the supervision of [David Filliat](https://www.researchgate.net/profile/David-Filliat). My doctoral research, titled \"[Continual Learning: Tackling Catastrophic Forgetting in Deep Neural Networks with Replay Processes](https://arxiv.org/abs/2007.00487),\" investigated the use of replay mechanisms, particularly generative models, for continual learning. I also explored replay for continual reinforcement learning and the theoretical limitations of regularizing dynamic architectures in continual learning. I hold a Master's degree in Electronics and Robotics from CPE Lyon.\n\nI love train 🚞 and bike 🚲 travelling, big trees 🌳 and playing chess ♟\n\n**Featured Research Projects:**\n\n* [Pretraining of Vision Transformers for Histopathology](https://arxiv.org/pdf/2501.05409)\n* [Continual pre-training of large language models.](https://arxiv.org/abs/2308.04014)\n* [Characterization of data distribution drifts.](https://arxiv.org/abs/2104.01678)\n* [A better understanding of continual learning models.](https://arxiv.org/abs/2106.01834)\n* [The impact of large pre-trained models for continual learning.](https://arxiv.org/abs/1912.03049)\n* [Continuum](https://github.com/Continvvm/continuum): A PyTorch-based library designed to facilitate continual learning experimentation through diverse benchmarks, aiming to accelerate progress in the field.\n* [continual\\_learning\\_papers](https://github.com/optimass/continual_learning_papers): A curated catalogue of continual learning papers\n\n[Google Scholar](https://scholar.google.com/citations?user=5NttkuoAAAAJ\u0026hl=en)\n[LinkedIn](https://linkedin.com/in/timoth%C3%A9e-lesort-128039aa)\n[Research Gate](https://www.researchgate.net/profile/Timothee-Lesort)\n[Semantic Scholar](https://www.semanticscholar.org/author/Timoth%C3%A9e-Lesort/26418330)\n[Twitter](https://twitter.com/tlesort)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftlesort%2Ftlesort","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ftlesort%2Ftlesort","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftlesort%2Ftlesort/lists"}
