DAStatFormer: A Hybrid Multibranch Transformer with Statistical Feature Integration for DAS-Based Pattern Recognitions
Michel Dione, Jerry Lonlac, Hélène Louis +2
Distributed Acoustic Sensing (DAS) enables large-scale monitoring through optical fibers, but its high dimensionality and complex spatio-temporal patterns make event classification…
Tackle CSM in JPEG Steganalysis with Data Adaptation
Rony Abecidan, Vincent Itier, Jérémie Boulanger +2
Steganalysis models excel on benchmark datasets but struggle in the wild when analyzed images are produced by a processing pipeline unseen during training. This problem known as Co…
Feller Property and Absorption of Diffusions for Multi-Species Metacommunities
Benoît Henry, Céline Wang
We consider individuals of two species distributed over m patches, each with a hosting capacity , where . We assume that all the patches are linked by the d…
DinoLizer: Separating VAE and Diffusion Artifacts in Generative Inpainting Localization
Minh Thong Doi, Vincent Itier, Jan Butora +2
We introduce DinoLizer, a DINOv2-based localizer of manipulated areas in generative inpainting. The model is trained to focus on semantically altered regions by treating reconstruc…
Maximize margins for robust splicing detection
Julien Simon de Kergunic, Rony Abecidan, Patrick Bas +1
Despite recent progress in splicing detection, deep learning-based forensic tools remain difficult to deploy in practice due to their high sensitivity to training conditions. Even…
The Directed Spanning Forest: coalescence versus dimension
Tom Garcia-Sanchez
For , the directed spanning forest (DSF) of dimension is an oriented random geometric graph whose vertex set is given by a homogeneous Poisson po…
Construction of ergodic IDLA forests in
Nicolas Chenavier, David Coupier, Keenan Penner +1
We prove the existence of infinite-volume IDLA forests in , with , based on a multi-source IDLA protocol. Unlike IDLA aggregates, the laws of the IDLA fore…
Online hand gesture recognition using Continual Graph Transformers
Rim Slama, Wael Rabah, Hazem Wannous
Online continuous action recognition has emerged as a critical research area due to its practical implications in real-world applications, such as human-computer interaction, healt…
The Planar Lattice Two-Neighbor Graph Percolates
David Coupier, Benoît Henry, Benedikt Jahnel +1
The k-neighbor graph is a directed percolation model on the hypercubic lattice Z d in which each vertex independently picks exactly k of its 2d nearest neighbors at random, and we…
GraphGrad: Efficient Estimation of Sparse Polynomial Representations for General State-Space Models
Benjamin Cox, Emilie Chouzenoux, Victor Elvira
State-space models (SSMs) are a powerful statistical tool for modelling time-varying systems via a latent state. In these models, the latent state is never directly observed. Inste…
Pick the Largest Margin for Robust Detection of Splicing
Julien Simon de Kergunic, Rony Abecidan, Patrick Bas +1
Despite advancements in splicing detection, practitioners still struggle to fully leverage forensic tools from the literature due to a critical issue: deep learning-based detectors…
Blind Data Adaptation to tackle Covariate Shift in Operational Steganalysis
Rony Abecidan, Vincent Itier, Jérémie Boulanger +2
The proliferation of image manipulation for unethical purposes poses significant challenges in social networks. One particularly concerning method is Image Steganography, allowing…
Stacking-based deep neural network for player scouting in football 1
Simon Lacan
Datascouting is one of the most known data applications in professional sport, and specifically football. Its objective is to analyze huge database of players in order to detect hi…
Line-of-sight Cox percolation on Poisson-Delaunay triangulation
David Corlin Marchand, David Coupier, Benoît Henry
In this work, percolation properties of device-to-device (D2D) networks in urban environments are investigated. The street system is modeled by a Poisson-Delaunay triangulation (PD…
Agreement Technologies for Coordination in Smart Cities
Holger Billhardt, Alberto Fernández, Marin Lujak +1
Many challenges in today's society can be tackled by distributed open systems. This is particularly true for domains that are commonly perceived under the umbrella of smart cities,…
Decentralizing Coordination in Open Vehicle Fleets for Scalable and Dynamic Task Allocation
Marin Lujak, Stefano Giordani, Andrea Omicini +1
One of the major challenges in the coordination of large, open, collaborative, and commercial vehicle fleets is dynamic task allocation. Self-concerned individually rational vehicl…
Reorienting Learning Game Design in Design-Based Research: a Case Study
Nadine Mandran, Estelle Prior, Eric Sanchez +1
One of the main difficulties remains the collaboration between the various experts involved in designing the Learning Games (LG). Our literature review focuses on the pitfalls and…
Basis restricted elastic shape analysis on the space of unregistered surfaces
Emmanuel Hartman, Emery Pierson, Martin Bauer +2
This paper introduces a new mathematical and numerical framework for surface analysis derived from the general setting of elastic Riemannian metrics on shape spaces. Traditionally,…
Leveraging Data Geometry to Mitigate CSM in Steganalysis
Rony Abecidan, Vincent Itier, Jérémie Boulanger +2
In operational scenarios, steganographers use sets of covers from various sensors and processing pipelines that differ significantly from those used by researchers to train stegana…
Pointwise Maximal Leakage on General Alphabets
Sara Saeidian, Giulia Cervia, Tobias J. Oechtering +1
Pointwise maximal leakage (PML) is an operationally meaningful privacy measure that quantifies the amount of information leaking about a secret to a single outcome of a related…
Using Set Covering to Generate Databases for Holistic Steganalysis
Rony Abecidan, Vincent Itier, Jérémie Boulanger +2
Within an operational framework, covers used by a steganographer are likely to come from different sensors and different processing pipelines than the ones used by researchers for…
Generating Multiple 4D Expression Transitions by Learning Face Landmark Trajectories
Naima Otberdout, Claudio Ferrari, Mohamed Daoudi +2
In this work, we address the problem of 4D facial expressions generation. This is usually addressed by animating a neutral 3D face to reach an expression peak, and then get back to…
Fusion of Physiological and Behavioural Signals on SPD Manifolds with Application to Stress and Pain Detection
Yujin WU, Mohamed Daoudi, Ali Amad +2
Existing multimodal stress/pain recognition approaches generally extract features from different modalities independently and thus ignore cross-modality correlations. This paper pr…
