I am a Master's degree student in Mathematics, Machine Learning & Computer Vision at the master MVA from ENS Paris-Saclay. I previously graduated from École Centrale de Lyon with an Engineering degree in Applied Mathematics.

I would like to pursue my studies with a PhD in Computer Vision! I am curious about many research directions in CV and I have recently enjoyed working with Pr. M. Aubry in the Imagine team on unsupervised and weakly-supervised problems with applications in text-line analysis. I am currently pursuing my Master's Thesis at Princeton University, working with Pr. J. Deng.

The Learnable Typewriter: A Generative Approach to Text Analysis
Y. Siglidis, N. Gonthier, J. Gaubil, T. Monnier, M. Aubry
arXiv 2023
Webpage   Paper   Code

We introduce a generative approach for character analysis and recognition in text lines that can perform using little to no supervision.


Research projects

Sparse variable selection in Lasso using Knockoffs
J. Marlhens, J. Gaubil. Advisor: Pr. Y. de Castro (Institut Camille Jordan)
Winter term 2022

Study of the control of False Discovery Rate via Knockoffs as proposed by R. Barber and E. Candès, and application to System Identification.

Object detection and 6D pose estimation for real-time Robotics
Advisor: Pr. E. Dellandrea (CNRS Liris)
May - Aug. 2021
Report  (french)

Literature review and evaluation of baseline Deep Learning approaches for real-time Object detection and 6D pose-estimation.

Research internship on the Robotics project Chiron in the LIRIS team, that aimed at creating a semi-autonomous robot assistant for hospitalized patients.

My contributions consisted in a 40 pages literature report of the field as well as fixing the codebase of an existing approach (FS-Net, CVPR'21) that further served as a baseline for the project. My work was then used as a basis by an incoming PhD student.

Incremental Deep Learning
J. Gaubil, Clément Martinelli. Advisor: Pr. E. Dellandrea (CNRS Liris)
Academic year 2020 - 2021
Report  (french)

Study of approaches to alleviate Catastrophic Forgetting when training an already optimized Neural Network on new samples or tasks.

Academic research project during 2nd year at École Centrale de Lyon. We delivered a 50-page report over core existing Incremental Deep Learning techniques and proposed a theoretical improvement of one of them (GEM).
