Data Science Seminar Series : Sihem Amer-Yahia from CNRS LIG Grenoble

on the October 26, 2017

15:30 to 17:30
The Data Science Seminar Series bring high profile researchers to Université Grenoble Alpes to show the increasing role of data science in modern research. It is open to all researchers of Université Grenoble Alpes. For the second seminar, we will welcome Sihem Amer-Yahia from CNRS LIG Grenoble.
Sihem Amer-Yahia  from CNRS LIG Grenoble will give a talk on “Toward Interactive User Data Analytics”. The event will take place on Thursday 26 October at IMAG building. The event will be followed by a coffee break.

User data can be acquired from various domains. This data is characterized by a combination of demographics such as age and occupation and user actions such as rating a movie, reviewing a restaurant or buying groceries. User data is appealing to analysts in their role as data scientists who seek to conduct large-scale population studies, and gain insights on various population segments. It is also appealing to novice users in their role as information consumers who use the social Web for routine tasks such as finding a book club or choosing a restaurant.  User data exploration has been formulated as identifying group-level behavior such as Asian women who publish regularly in databases. Group level exploration enables new findings and addresses issues raised by the peculiarities of user data such as noise and sparsity. I will review our work on one-shot and interactive user data exploration. I will then describe the challenges of developing a visual analytics tool for finding and connecting users and groups.
