  • 13:45-14:45 Jean-Daniel Fekete : Infrastructures for Visual Analytics: You are in a maze of twisty little passages, all alike!

Abstract: When designing visual analytics systems, we lack support from existing software and hardware infrastructures. The wide diversity of systems components available nowadays increases the confusion by providing more possible architectures, each slightly different and none designed with visual analytics requirements in mind. This is the case for Cloud infrastructures, Grids, GPGPUs, Web services, NoSQL databases, to name a few. In this talk, I will present an organized landscape of existing architectures at the three levels of the visual analytics pipeline: data management, analysis, and visualization. I will then propose some high-level principles and requirements for visual analytics infrastructures to find our way in the maze of choices.

  • 11:25-12:25 Helwig Hauser: The Iterative Process of Interactive Visual Analysis

Abstract: One central characteristic of our information age is that increasingly often we should ex­ploit the wealth of available data for the sake of learning, decision making, as well as other tasks.  A promising approach – not at the least also targeted by visual analytics – is to integrate the strengths of computers (fast computation, efficient handling of large datasets, comparably low costs, etc.) with the strengths of the users (perceptual capabilities, considering domain know­ledge, detecting the unexpected, etc.).  In this talk, we look at one possible solution, i.e., the concept of interactive visual analysis, and describe it as an iterative process, enabling the integration of computational and interactive means for data exploration and analysis.  We consider a data scenario that opposes dependent and independent data dimensions (like in a table), general enough to match many different application cases.  We focus on the case of multivariate data, but also address the case of high-dimensional data and opportunities for exploring and analyzing such data.  After all, we think of interactive visual analysis as an iterative process, where each step is performed on the basis of a toolbox with computational and interactive visual solutions.
