Zacharie ALES


I am currently an associate professor at ENSTA in the UMA laboratory. I am also associated to the OC team of the CEDRIC laboratory.

From 2015 to 2017 I was an associate professor at the University of Avignon in the team Operational Research and Optimisation of the LIA laboratory.

I obtained my PhD in 2014 from INSA de Rouen in the LMI and LITIS laboratories under the supervision of Christian Gout, Laurent Vercouter, Arnaud Knippel and Alexandre Pauchet.

The aim of my thesis (available here in french) was to extract regularities in two-dimensional dialogue annotations. To this end we developped a two-step methodology in which recurrent patterns are first extracted (using approaches based on bioinformatic algorithms) and then clustered (either thanks to heuristics or by solving a mixed integer program). The methods have been implemented in a decision aid software called VIESA.
