Disentangling Hallucinations: Orthogonal Semantic Projection for Robust Interpretability

Emirhan Bilgiç, Baptiste Caramiaux, Zhi Yan +1

As Vision-Language Models are increasingly deployed in safety-critical applications, the trustworthiness of their explanations becomes crucial. Explainable AI (XAI) methods for Vis…

A Geometric Unification of Concept Learning with Concept Cones

Alexandre Rocchi, Thomas Fel, Gianni Franchi

Two traditions of interpretability have evolved side by side but seldom spoken to each other: Concept Bottleneck Models (CBMs), which prescribe what a concept should be, and Sparse…

From Local Geometry to Global Pseudo Labeling for Robust Positive Unlabeled Learning under Covariate Shift

Firas Gabetni, Alexandre Rocchi Henry, Alexandre Rocchi +3

Detecting covariate shift is critical for building reliable vision systems. While most prior work focuses on improving robustness to shift, explicitly detecting covariate shift rem…

SS3D: End2End Self-Supervised 3D from Web Videos

Marwane Hariat, Gianni Franchi, David Filliat +1

We present SS3D, a web-scale SfM-based self-supervision pretraining pipeline for feed-forward 3D estimation from monocular video. Our model jointly predicts depth, ego-motion, and…

FakeParts: a New Family of AI-Generated DeepFakes

Ziyi Liu, Firas Gabetni, Awais Hussain Sani +5

We introduce FakeParts, a new class of deepfakes characterized by subtle, localized manipulations to specific spatial regions or temporal segments of otherwise authentic videos. Un…

Double Descent Meets Out-of-Distribution Detection: Theoretical Insights and Empirical Analysis on the role of model complexity

Mouïn Ben Ammar, David Brellmann, Arturo Mendoza +2

Out-of-distribution (OOD) detection is essential for ensuring the reliability and safety of machine learning systems. In recent years, it has received increasing attention, particu…
