A Window-based Approach for Mining Long Duration Event-sequences
(The Eurographics Association, 2020)
This paper presents an interactive sequence mining approach for exploring long duration event-sequences and identifying interesting patterns within them. The approach extends previous work on exploratory sequence mining ...
Towards the Detection and Visual Analysis of COVID-19 Infection Clusters
(The Eurographics Association, 2021)
A major challenge for departments of public health (DPHs) in dealing with the ongoing COVID-19 pandemic is tracing contacts in exponentially growing SARS-CoV2 infection clusters. Prevention of further disease spread requires ...
Quality Metrics to Guide Visual Analysis of High Dimensional Genomics Data
(The Eurographics Association, 2020)
Studies of genome sequenced data are increasingly common in many domains. Technological advances enable detection of hundreds of thousands of biological entities in samples, resulting in extremely high dimensional data. ...
Customizable Coordination of Independent Visual Analytics Tools
(The Eurographics Association, 2021)
While it is common to use multiple independent analysis tools in combination, it is still cumbersome to carry out a cross-tool visual analysis. Some dedicated frameworks addressing this issue exist, yet in order to use ...
Progressive Parameter Space Visualization for Task-Driven SAX Configuration
(The Eurographics Association, 2020)
As time series datasets are growing in size, data reduction approaches like PAA and SAX are used to keep them storable and analyzable. Yet, finding the right trade-off between data reduction and remaining utility of the ...
SpatialRugs: Enhancing Spatial Awareness of Movement in Dense Pixel Visualizations
(The Eurographics Association, 2020)
Compact visual summaries of spatio-temporal movement data often strive to express accurate positions of movers. We present SpatialRugs, a technique to enhance the spatial awareness of movements in dense pixel visualizations. ...
Immersive Analytics of Heterogeneous Biological Data Informed through Need-finding Interviews
(The Eurographics Association, 2021)
The goal of this work is to improve existing biological analysis processes by means of immersive analytics. In a first step, we conducted need-finding interviews with 12 expert biologists to understand the limits of current ...
An Exploratory Visual Analytics Tool for Multivariate Dynamic Networks
(The Eurographics Association, 2020)
Visualizing multivariate dynamic networks is a challenging task. The evolution of the dynamic network within the temporal axis must be depicted in conjunction with the associated multivariate attributes. In this paper, an ...
Dual Radial Set
(The Eurographics Association, 2020)
Set-typed data visualizations require novel interactive representations, especially when visualizing multiple set-typed data attributes. The challenge is how to effectively analyze relations between data elements from ...
Lessons learned while supporting Cyber Situational Awareness
(The Eurographics Association, 2021)
The increasing number of cyberattacks against critical infrastructures has pushed researchers to develop many Visual Analytics solutions to provide valid defensive approaches and improve the situational awareness of the ...
