A Survey and Implementation of Performance Metrics for Self-Organized Maps

1 code implementation11 Nov 2020 Florent Forest, Mustapha Lebbah, Hanane Azzag, Jérôme Lacaille

Quantitative evaluation of self-organizing maps (SOM) is a subset of clustering validation, which is a challenging problem as such.

Selecting the Number of Clusters $K$ with a Stability Trade-off: an Internal Validation Criterion

1 code implementation15 Jun 2020 Alex Mourer, Florent Forest, Mustapha Lebbah, Hanane Azzag, Jérôme Lacaille

In this perspective, clustering stability has emerged as a natural and model-agnostic principle: an algorithm should find stable structures in the data.

Deep Embedded SOM: Joint Representation Learning and Self-Organization

1 code implementation ESANN 2019 2019 Florent Forest, Mustapha Lebbah, Hanene Azzag, Jérôme Lacaille

In the wake of recent advances in joint clustering and deep learning, we introduce the Deep Embedded Self-Organizing Map, a model that jointly learns representations and the code vectors of a self-organizing map.

Search Strategies for Binary Feature Selection for a Naive Bayes Classifier

no code implementations12 Jun 2015 Tsirizo Rabenoro, Jérôme Lacaille, Marie Cottrell, Fabrice Rossi

We compare in this paper several feature selection methods for the Naive Bayes Classifier (NBC) when the data under study are described by a large number of redundant binary indicators.
