Mathematics

Persistence-based clustering with outlier-removing filtration

This article describes a non-parametric clustering algorithm with an outlier removal step. Our method is based on tools from topological data analysis: we define a new filtration on metric spaces which is a variant of the Vietoris–Rips filtration…

Assessment of the depth of anesthesia with hidden Markov model based on cardiopulmonary variables

Background Precise monitoring of the Depth of Anesthesia (DoA) is essential to prevent intra-operative awareness (in case of underdosage) or increased post-operative morbi-mortality (in case of overdosage). The recording of a high- frequency…

Automatic gait events detection with inertial measurement units: healthy subjects and moderate to severe impaired patients

Abstract Background Recently, the use of inertial measurement units (IMUs) in quantitative gait analysis has been widely developed in clinical practice. Numerous methods have been developed for the automatic detection of gait events (GEs). While…

MaskSim: Detection of synthetic images by masked spectrum similarity analysis

Synthetic image generation methods have recently revolutionized the way in which visual content is created. This opens up creative opportunities but also presents challenges in preventing misinformation and crime. However, these methods leave traces…

Subspace clustering sur données incomplètes par imputation multiple

Nous nous intéressons à la classification non supervisée en grande dimension en présence d'observations incomplètes. Nous proposons une approche d'imputation multiple avec comme modèle d'analyse la méthode Reduced KMeans de subspace clustering. L…

Repulsive Shells

This paper develops a shape space framework for collision-aware geometric modeling, where basic geometric operations automatically avoid inter-penetration. Shape spaces are a powerful tool for surface modeling, shape analysis, nonrigid motion…
