"Profiling User Interactions on Social Networks"

Dr. Cuneyt Akcora, State University of New York at Buffalo, 26 de octubre 2017, 18:00 h Salón 202, Río Hondo ITAM

Summary:

In this talk, we will describe our work in augmenting network connections by using information from user interactions with applications in Trust, Anomaly Detection, Privacy and Link Predicction. In these studies we used social network data primarily from Facebook, Twitter, Orkut, and scientific network data from DBLP and the ACM digital library. We will outline the Homophily and Heterophily  theories and explain how we can quantify online user behavior in terms of these theories. Our research indicates that most users choose to live in a closed bubble of Homophily, and this tendency can be used against their privacy. Throughout the talk we will describe the state of the art in privacy research and explain how governments and organizations pry data out of a social network.

BIOGRAPHY. Cuneyt was a Fulbright Scholar at the State University of New York at Buffalo, where he worked on public opinion mining and sentiment analysis on microblogs. In 2014, he completed his Ph.D. at the Università Degli Studi Dell'Insubria in Italy, under the supervision of Elena Ferrari and Barbara Carminati.  His Ph.D. studies focused on analyzing privacy effects of user interactions on online social networks. He visited the Social Computing Group (Francesco Bonchi) at Yahoo! Research Barcelona (2011), Data Security and Privacy lab (Murat Kantarcioglu) at the University of Texas at Dallas (2012) and the Data Analytics Group (Paolo Papotti) of Qatar Computing Research Institute (2014). Before starting his Post-Doctoral studies at the University of Texas at Dallas in 2016, he worked at the Intelligent Search Lab at Huawei Research Turkey.


"Coordinación de Movimiento en Sistemas Multi-Agente"

Dr. Jesús Santiaguillo Salinas, CINVESTAV-IPN, 27 de octubre 2017, 11:00 h Salón 110, Río Hondo ITAM

Resumen:

Los sistemas multi-agente son grupos de varios robots móviles que interactúan y se coordinan entre si para realizar tareas complejas. Una de las principales aplicaciones de estos sistemas es la coordinación de movimiento donde algunos de los problemas a tratar son formación, seguimiento en formación y consenso, considerando también el problema de evasión de colisiones. En esta plática se abordan problemas de coordinación de movimiento en sistemas multi-agente conformados por robots de tracción diferencial y helicóptero de 4  rotores.
