GroCo: Ground Constraint for Metric Self-Supervised Monocular Depth

ECCV 2024poster

"Monocular depth estimation has greatly improved in the recent years but models predicting metric depth still struggle to generalize across diverse camera poses and datasets. While recent supervised methods mitigate this issue by leveraging ground prior information at inference, their adaptability t…

What Does My GNN Really Capture? On Exploring Internal GNN Representations

IJCAI 2022poster

Graph Neural Networks (GNNs) are very efficient at classifying graphs but their internal functioning is opaque which limits their field of application. Existing methods to explain GNN focus on disclosing the relationships between input graphs and model decision. In this article, we propose a method…

Logistic similarity metric learning for face verification

ICASSP 2015accepted

This paper presents a new method for similarity metric learning, called Logistic Similarity Metric Learning (LSML), where the cost is formulated as the logistic loss function, which gives a probability estimation of a pair of faces being similar. Especially, we propose to shift the similarity decisi…
