Since October 2015, I'm a PhD Student at the University of Nantes, under the direction of Yannick Prié and Julien Blanchard. I work with the DUKe (Data User Knowledge) team, within the LINA (Laboratoire Informatique Nantes Atlantique) laboratory.
My subject is Interactive instantaneous evolving pattern mining for activity data exploration. The goal of this work is to provide tools allowing an analyst to study user behaviours on a given environment, and their evolution. The user activity is recorded within interaction traces, which we explore using pattern mining techniques. Our hypothesis is that user behaviours could be expressed with patterns, which could be combined as "evolving patterns" to express the behaviours' evolution over time. Considering our goal of producing tools to help an analyst, we are also interested in their ability to be as interactive as possible. To solve the conflict between this instantaneousness and the potentially long execution time of pattern mining algorithms, we are also interested by the ideas expressed in the domain of progressive visual analytics.
