AboutI am an aspiring Computer Vision researcher, and I am excited about developing robust methods for perceiving, understanding, and interacting with the physical world from images using minimal supervision. I am currently working with Maks Ovsjanikov at École Polytechnique at the intersection of Computer Vision and Geometry. I am applying for PhDs for Fall 2025! Please reach out if you are interested in working with me. In the past, I had the privilege to collaborate with and learn from fantastic researchers to start advancing towards this goal. Recently, I have been extremely lucky to work with Prof. Vincent Sitzmann at MIT CSAIL, developing Self-supervised 3D generation methods. I previously spent two wonderful summer working on learning representations for highly-dynamic scenes with Prof. Jia Deng at Princeton University, and with Prof. Mathieu Aubry on weakly-supervised document analysis. NewsFeb. 2025 - Thrilled to begin working with Prof. Maks Ovsjanikov at École Polytechnique! Sep. 2024 - The Learnable Typewriter won the Best paper award at ICDAR 2024, kudos Ioannis! Mar. 2024 - The Learnable Typewriter - our paper on document analysis using weak or no supervision - has been accepted to ICDAR 2024! Feb. 2024 - Excited to start my visiting stay with Prof. Vincent Sitzmann in the Scene Representation Group! Sep. 2023 - I obtained the Master MVA from École Normale Supérieure Paris-Saclay!

The Learnable Typewriter: A Generative Approach to Text AnalysisI. Siglidis, N. Gonthier, J. Gaubil, T. Monnier, M. AubryICDAR 2024 ⭐ Best Paper Award ⭐ We introduce a generative approach for character analysis and recognition in text line images that can perform using little to no supervision. ProjectsHere are listed some course projects that I enjoy sharing and that are representative of my past and current research interests.
Self-Supervised Learning of Visual RepresentationsStudy of the recently proposed VICReg and SimCLR, evaluation of the representations learned by VICReg on a challenging downstream task of Fine-grained image Classification and in a small dataset setting. Weakly-Supervised Visual Character Discovery and AnalysisDevelopments of the Learnable Typewriter, using several learned prototypes per character instead of a single one, which then made it to the final paper. Design of a richer transformation scheme by using Thin Plate Spline transformations. Neural Point-based rendering and View SynthesisStudy of the point-based Scene Representation Scuplted Neural Points. Evaluation of the proposed sculpting mechanism, ablation study and proposition of improvements. Gamma Denoising Diffusion Implicit ModelsStudy of Denoising Diffusion Implicit Models, drawing parallels with Deep Equilibrium models, experimenting with different subsampling methods and proposing an - at the time - first derivation of the backward process for Gamma-DDIMs. |
