Hierarchical Stochastic Neighbor Embedding
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
In recent years, dimensionality-reduction techniques have been developed and are widely used for hypothesis generation in Exploratory Data Analysis. However, these techniques are confronted with overcoming the trade-off ...
Exploring Items and Features with IF,FI-Tables
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
The exploration of high-dimensional data is challenging because humans have difficulty to understand more than three dimensions. We present a new visualization concept that enables users to explore such data and, specifically, ...
EuroVis 2016: Frontmatter
(Eurographics Association, 2016)
The Grassmannian Atlas: A General Framework for Exploring Linear Projections of High-Dimensional Data
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Linear projections are one of the most common approaches to visualize high-dimensional data. Since the space of possible projections is large, existing systems usually select a small set of interesting projections by ranking ...
TimeArcs: Visualizing Fluctuations in Dynamic Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
In this paper we introduce TimeArcs, a novel visualization technique for representing dynamic relationships between entities in a network. Force-directed layouts provide a way to highlight related entities by positioning ...
Visual Debugging Techniques for Reactive Data Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Interaction is critical to effective visualization, but can be difficult to author and debug due to dependencies among input events, program state, and visual output. Recent advances leverage reactive semantics to support ...
Visual Analysis of Tumor Control Models for Prediction of Radiotherapy Response
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
In radiotherapy, tumors are irradiated with a high dose, while surrounding healthy tissues are spared. To quantify the probability that a tumor is effectively treated with a given dose, statistical models were built and ...
A Visual Analytics Framework for Microblog Data Analysis at Multiple Scales of Aggregation
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Real-time microblogs can be utilized to provide situational awareness during emergency and disaster events. However, the utilization of these datasets requires the decision makers to perform their exploration and analysis ...
MCFTLE: Monte Carlo Rendering of Finite-Time Lyapunov Exponent Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Traditionally, Lagrangian fields such as finite-time Lyapunov exponents (FTLE) are precomputed on a discrete grid and are ray casted afterwards. This, however, introduces both grid discretization errors and sampling errors ...
AVOCADO: Visualization of Workflow-Derived Data Provenance for Reproducible Biomedical Research
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
A major challenge in data-driven biomedical research lies in the collection and representation of data provenance information to ensure that findings are reproducibile. In order to communicate and reproduce multi-step ...
