An Efficient Shapley Value Computation for the Naive Bayes Classifier

no code implementations31 Jul 2023 Vincent Lemaire, Fabrice Clérot, Marc Boullé

In the case of the naive Bayes classifier, and to our knowledge, there is no ``analytical" formulation of Shapley values.

Co-clustering based exploratory analysis of mixed-type data tables

no code implementations22 Dec 2022 Aichetou Bouchareb, Marc Boullé, Fabrice Clérot, Fabrice Rossi

Co-clustering is a class of unsupervised data analysis techniques that extract the existing underlying dependency structure between the instances and variables of a data table as homogeneous blocks.

Un modèle Bayésien de co-clustering de données mixtes

no code implementations6 Feb 2019 Aichetou Bouchareb, Marc Boullé, Fabrice Rossi, Fabrice Clérot

The proposed model infers an optimal segmentation of all variables then performs a co-clustering by minimizing a Bayesian model selection cost function.

A Study of the Spatio-Temporal Correlations in Mobile Calls Networks

no code implementations30 Oct 2015 Romain Guigourès, Marc Boullé, Fabrice Rossi

In this article, we introduce a practical analysis of a large database from a telecommunication operator.

Universal Approximation of Edge Density in Large Graphs

no code implementations6 Aug 2015 Marc Boullé

In this paper, we present a novel way to summarize the structure of large graphs, based on non-parametric estimation of edge density in directed multigraphs.

Cats & Co: Categorical Time Series Coclustering

no code implementations6 May 2015 Dominique Gay, Romain Guigourès, Marc Boullé, Fabrice Clérot

We suggest a novel method of clustering and exploratory analysis of temporal event sequences data (also known as categorical time series) based on three-dimensional data grid models.

Country-scale Exploratory Analysis of Call Detail Records through the Lens of Data Grid Models

no code implementations20 Mar 2015 Romain Guigourès, Dominique Gay, Marc Boullé, Fabrice Clérot, Fabrice Rossi

Call Detail Records (CDRs) are data recorded by telecommunications companies, consisting of basic informations related to several dimensions of the calls made through the network: the source, destination, date and time of calls.
