Abstract

National audience; This paper takes a step towards the extraction of contrastive explanations between anoma- lies and the intrinsic structure of regular points. It proposes a variant of the isolation forest algorithm whose main objective is to preserve the structure of regular data in order to facilitate its reconstruction. Experiments conducted on synthetic datasets show that this variant of isola- tion forest deteriorates less the structure of regular data than the classical method. Therefore, the former can serve as a basis for a unified approach to anomaly detection and explanation.; Cet article effectue un pas vers une extraction d'explications contrastives entre anomalies et structure intrinsèque des points réguliers. Il propose une variante de l'algorithme des forêts d'isolation ayant pour objectif principal la préservation de la structure des données régulières en vue de sa reconstitution plus aisée. Les expérimentations menées sur des jeux de données synthétiques montrent que cette variante des forêts d'isolation détériore moins la structure des données régulières que la méthode classique. Par conséquent, la première citée peut servir de base pour une approche unifiée de détection et d'explication d'anomalies.

Abstract

This paper describes FuzViz, a tool to explore interactively massive relational data. FuzViz relies on a method building automatically linguistic summaries, that provide concise and intelligible insights in the data content. It offers an interactive view of these summaries, dynamically recomputed on demand. To ensure a fluid exploration of the data, FuzViz exploits the proposition of a highly efficient method for estimating the cardinality ofthe summary properties, estimated from statistics about the data distribution stored in the relational data base, consolidated by a sampling-based approach. The proposed workflow also involves a vocabulary inference mechanism from these statistics., Cet article présente un outil d'exploration interactive de données massives stockées dans un système de gestion de base de données (SGBD), nommé FuzViz. Il repose sur une méthode de construction automatique de résumés linguistiques, qui fournissent une synthèse concise et intelligible du contenu des données. Il offre une vue interactive de ces résumés recalculée dynamiquement selon les demandes de l'utilisateur. Pour assurer une exploration fluide des propriétés décrites par ces résumés, FuzViz s'appuie sur la proposition d'une méthode efficace d'estimations de leurs cardinalités, produites à partir des statistiques sur la distribution des données gérées par le SGBD et consolidées par une approche basée sur un échantillonnage. L'outil propose de plus un mécanisme d'inférence de vocabulaire flou à partir de ces statistiques.

Abstract

The paper addresses the tasks of anomaly detection and explanation simultaneously, in the human-in-the-loop paradigm integrating the end-user expertise : it first proposes to exploit two complementary data representations to identify anomalies, namely the description induced by the raw features and the description induced by a userdefined vocabulary. These representations respectively lead to identify so-called data-driven and knowledge driven anomalies. The paper then proposes to confront these two sets of instances so as to improve the detection step and to dispose of tools towards anomaly explanations. It distinguishes and discusses three cases, underlining how the two description spaces can benefit from oneanother, in terms of accuracy and interpretability., La personnalisation par prise en compte de l'expertise de l'utilisateur des processus de détection d'anomalies est le sujet principal de cet article. Les anomalies sont identifiées dans deux espaces de représentation des données, l'espace initial composé des valeurs brutes et l'espace induit par un vocabulaire flou défini par l'utilisateur sur ces attributs initiaux. L'application de toute méthode de détection d'anomalies sur ces deux espaces conduit à différencier des anomalies issues des données brutes de celles issues du vocabulaire. Afin à la fois d'améliorer la détection des exceptions et de disposer d'outils pour les expliquer, ces deux ensembles d'anomalies sont confrontés. Trois situations émanant de cette comparaison sont étudiées afin de montrer comment l'utilisation combinée des deux espaces améliore l'efficacité de la procédure de détection d'anomalies ainsi que l'interprétabilité des résultats qu'elle génère.
