MAGDiff: Covariate Data Set Shift Detection via Activation Graphs of Deep Neural Networks

1 code implementation22 May 2023 Felix Hensel, Charles Arnal, Mathieu Carrière, Théo Lacombe, Hiroaki Kurihara, Yuichi Ike, Frédéric Chazal

Despite their successful application to a variety of tasks, neural networks remain limited, like other machine learning methods, by their sensitivity to shifts in the data: their performance can be severely impacted by differences in distribution between the data on which they were trained and that on which they are deployed.

RipsNet: a general architecture for fast and robust estimation of the persistent homology of point clouds

1 code implementation3 Feb 2022 Thibault de Surrel, Felix Hensel, Mathieu Carrière, Théo Lacombe, Yuichi Ike, Hiroaki Kurihara, Marc Glisse, Frédéric Chazal

The use of topological descriptors in modern machine learning applications, such as Persistence Diagrams (PDs) arising from Topological Data Analysis (TDA), has shown great potential in various domains.

Image analysis for Alzheimer's disease prediction: Embracing pathological hallmarks for model architecture design

no code implementations12 Nov 2020 Sarah C. Brüningk, Felix Hensel, Catherine R. Jutzeler, Bastian Rieck

Alzheimer's disease (AD) is associated with local (e. g. brain tissue atrophy) and global brain changes (loss of cerebral connectivity), which can be detected by high-resolution structural magnetic resonance imaging.
