Título: Analysis of competition and visibility in complex networks

Palestrante: Prof. Eitan Altman (INRIA)
Dia: 1 de agosto (sexta-feira)
Hora: 10 às 11:30
Sala: H-324B


Abstract:
We shall present an overview of our research on competition over popularity and visibility in complex networks, which is part of the CONGAS European project. The overview will begin by describing datasets that we collected on 1. evolution of the viewcount in youtube, 2. The recommendation graph in youtube. We shall show how these datasets were used for analysis, prediction and dimensioning purposes. We shall present several of our research activities : 1. An analysis of recommendation systems, 2. Resource allocation issues using static and dynamic versions of the Kelly mechanism. We shall discuss applications to social networks and vaccination in a dynamic epidemic model.

Eitan Altman received the B.Sc. degree in electrical engineering (1984), the B.A. degree in physics (1984) and the Ph.D. degree in electrical engineering (1990), all from the Technion-Israel Institute, Haifa. In (1990) he further received his B.Mus. degree in music composition in Tel-Aviv university. Since 1990, Dr. Altman has been a researcher at INRIA (National research institute in computer science and control) in Sophia-Antipolis, France. He has been in the editorial boards of several scientific journals: Wireless Networks (WINET), Computer Networks (COMNET), Computer Communications (Comcom), J. Discrete Event Dynamic Systems (JDEDS), SIAM J. of Control and Optimisation (SICON), Stochastic Models, and Journal of Economy Dynamic and Control (JEDC). He received the best paper award in the Networking 2006, in Globecom 2007, in IFIP Wireless Days 2009 and in CNSM 2011 (Paris) conferences. His areas of interest include Network Engineering Games, social networks and their control. He received in 2012 the Grand Prix de France Telecom from the French Academy of Sciences.
