An Evidential Neural Network Model for Regression Based on Random Fuzzy Numbers

no code implementations1 Aug 2022 Thierry Denoeux

We introduce a distance-based neural network model for regression, in which prediction uncertainty is quantified by a belief function on the real line.

Evidence fusion with contextual discounting for multi-modality medical image segmentation

1 code implementation23 Jun 2022 Ling Huang, Thierry Denoeux, Pierre Vera, Su Ruan

As information sources are usually imperfect, it is necessary to take into account their reliability in multi-source information fusion tasks.

Application of belief functions to medical image segmentation: A review

no code implementations3 May 2022 Ling Huang, Su Ruan, Thierry Denoeux

The investigation of uncertainty is of major importance in risk-critical applications, such as medical image segmentation.

Reasoning with fuzzy and uncertain evidence using epistemic random fuzzy sets: general framework and practical models

no code implementations16 Feb 2022 Thierry Denoeux

We introduce a general theory of epistemic random fuzzy sets for reasoning with fuzzy or crisp evidence.

Clustering acoustic emission data streams with sequentially appearing clusters using mixture models

2 code implementations25 Aug 2021 Emmanuel Ramasso, Thierry Denoeux, Gael Chevallier

The interpretation of unlabeled acoustic emission (AE) data classically relies on general-purpose clustering methods.

Fusion of evidential CNN classifiers for image classification

no code implementations23 Aug 2021 Zheng Tong, Philippe Xu, Thierry Denoeux

We propose an information-fusion approach based on belief functions to combine convolutional neural networks.

Deep PET/CT fusion with Dempster-Shafer theory for lymphoma segmentation

no code implementations11 Aug 2021 Ling Huang, Thierry Denoeux, David Tonnelet, Pierre Decazes, Su Ruan

Single-modality volumes are trained separately to get initial segmentation maps and an evidential fusion layer is proposed to fuse the two pieces of evidence using Dempster-Shafer theory (DST).

Evidential segmentation of 3D PET/CT images

1 code implementation27 Apr 2021 Ling Huang, Su Ruan, Pierre Decazes, Thierry Denoeux

In this paper, a segmentation method based on belief functions is proposed to segment lymphomas in 3D PET/CT images.

EGMM: an Evidential Version of the Gaussian Mixture Model for Clustering

no code implementations3 Oct 2020 Lianmeng Jiao, Thierry Denoeux, Zhun-Ga Liu, Quan Pan

The Gaussian mixture model (GMM) provides a simple yet principled framework for clustering, with properties suitable for statistical inference.

NN-EVCLUS: Neural Network-based Evidential Clustering

no code implementations27 Sep 2020 Thierry Denoeux

Evidential clustering is an approach to clustering based on the use of Dempster-Shafer mass functions to represent cluster-membership uncertainty.

Belief functions induced by random fuzzy sets: A general framework for representing uncertain and fuzzy evidence

no code implementations24 Apr 2020 Thierry Denoeux

We revisit Zadeh's notion of "evidence of the second kind" and show that it provides the foundation for a general theory of epistemic random fuzzy sets, which generalizes both the Dempster-Shafer theory of belief functions and possibility theory.

An Interval-Valued Utility Theory for Decision Making with Dempster-Shafer Belief Functions

no code implementations13 Dec 2019 Thierry Denoeux, Prakash P. Shenoy

The main goal of this paper is to describe an axiomatic utility theory for Dempster-Shafer belief function lotteries.

Decision Making

Calibrated model-based evidential clustering using bootstrapping

no code implementations12 Dec 2019 Thierry Denoeux

We then construct an evidential partition such that the pairwise belief and plausibility degrees approximate the bounds of the confidence intervals.

Decision-Making with Belief Functions: a Review

no code implementations16 Aug 2018 Thierry Denoeux

Approaches to decision-making under uncertainty in the belief function framework are reviewed.

Logistic Regression, Neural Networks and Dempster-Shafer Theory: a New Perspective

no code implementations5 Jul 2018 Thierry Denoeux

We revisit logistic regression and its nonlinear extensions, including multilayer feedforward neural networks, by showing that these classifiers can be viewed as converting input or higher-level features into Dempster-Shafer mass functions and aggregating them by Dempster's rule of combination.
