(NeurIPS2024) Supra-Laplacian Encoding for Transformer on Dynamic Graphs

Published in 38th Conference on Neural Information Processing Systems (NeurIPS 2024), 2024

We design a new spatio-temporal encoding for Dynamic Graph Transformers based on the spectral propreties of its associated supra-laplacian matrix.

(TMLR) ITEM: Improving Training and Evaluation of Message-Passing based GNNs for top-k recommendation

Published in Transaction on Machine Learning Research, 2024

First paper of the PhD. I worked on the improvement of Message-Passing based GNN for the task of top-k recommandation. Our contribution is to use a loss that better align the item ranking of a user

(QUIET DRONES) Deeplomatics: A deep-learning based multimodal approach for aerial drone detection and localization

Published in QUIET DRONES Second International e-Symposium on UAV/UAS Noise, 2022

I participated in the DEEPLOMATICS project as a research engineer at the CEDRIC laboratory of CNAM from October 2020 to September 2021. My task was to design a drone detection algorithm on images from very few amount of labeled data.
