Proceedings ArticleDOI
Visual cluster exploration of web clickstream data
TL;DR: A visual analytics system to explore the various user behavior patterns reflected by distinct clickstream clusters using a Self-Organizing Map with Markov chain models and enhancing their ability to reason is introduced.
Proceedings ArticleDOI
A sketch-based interface for classifying and visualizing vector fields
TL;DR: This work employs an automatic clustering method to generate field-line templates for the user to locate subfields of interest and leverages the user's knowledge about the flow field through intuitive user interaction, resulting in a promising alternative to existing flow visualization solutions.
Proceedings ArticleDOI
Visual analysis of massive web session data
TL;DR: This work introduces a two-tier visual analysis system, TrailExplorer2, to discover knowledge from massive log data by visualizing a sorted list of web sessions' temporal patterns and enables data exploration at different levels of details.
Proceedings ArticleDOI
Dual space analysis of turbulent combustion particle data
TL;DR: A dual-space method is introduced to analyze particle data in combustion simulations, starting by clustering the time series curves in the phase space of the data, and then visualizing the corresponding trajectories of each cluster in the physical space.
Proceedings ArticleDOI
Group dynamics in scientific visualization
TL;DR: This paper presents the first full group tracking framework in which they track groups (clusters) of features in time-varying 3D fluid flow simulations, and uses a clustering algorithm to group interacting features.
