Grandata Participated in UCOOL Workshop in Paris

by Carlos Sarraute, Grandata.

On October 6 and 7, 2014, I participated in the UCOOL workshop in Paris. The UCOOL project is about understanding and predicting human demanded content and mobility, and gathers participants from France, Brazil, Chile and Argentina.

During the workshop we had very interesting presentations. Artur Ziviani (from LNCC, Brazil) talked about a formal framework to work with time-varying multilayer networks. Marton Karsai (from ENS Lyon) gave a great presentation on spatiotemporal correlations and information spreading in mobile phone communication networks. Eduardo Mucelli (from Ecole Polytechnique and INRIA) spoke about measurement-driven mobile data traffic modeling in a large metropolitan area. We also had presentations from Werner Creixel (USM, Valparaiso, Chile), Hakima Chaouchi (Telecom Sud Paris) and Anelise Munaretto (UTFPR, Brazil). I presented with Jorge Brea our work on the inference of users demographic attributes (such as gender and age), based on their mobile phone usage patterns, and the topology of their social network.

After the workshop, I spent more time working with the group at INRIA Saclay, in the campus of the Ecole Polytechnique, and with the group at ENS Lyon. These were very productive days, and we are advancing in a wide range of projects: 

detecting socio-cultural events,

analyzing and modeling the demand of web traffic of mobile users,

understanding correlations between different layers of human behavior (e.g. their spending behavior and their mobile phone communications), using the fact that we have a dynamic view of both layers,

summarize the geographic mobility information in aggregated variables, which can be used to refine other classifications (e.g. the age and gender classification).

Also, in Lyon, I got the chance to see the Lego Turing machine made by Yannick Leo and others (link).

Many thanks to Aline Viana (from INRIA Saclay) who organized the workshop, invited me to participate and was a great host. Finally, I look forward to the next meeting of the UCOOL team, in Valparaiso in 2015!
