Cher Gérard,

Merci pour cette invitation qui nous donnera probablement
l'occasion de nous connaître scientifiquement.

Voici le titre et le résumé d'un travail initié avec Mustapha Lebbah.

Amitiés,

Younès.


3M-SOM : Learning Self Organizing Maps as a Markov Mixture Models
Mustapha Lebbah and Younès Bennani

Abstract:
This paper describes a new algorithm  to learn  Self-Organizing Maps (SOM) as a Markov Mixture Models The new model that we present is valid for all structure of graphical model. 3M-SOM realizes an unsupervised learning using unlabelled evolutionary  data sets, namely those that describe sequential data. We use E-M (Expectation-Maximisation) standard algorithm to maximize the likelihood. The graph structure is integrated in the parameter estimation  of markov model using a neighborhood function to learn a topographic clustering.  The 3M-SOM model  provides a self-organizing markov model  using an original learning algorithm.
