ChronoCorrelator: Enriching Events with Time Series
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Event sequences and time series are widely recorded in many application domains; examples are stock market prices, electronic health records, server operation and performance logs. Common goals for recording are monitoring, ...
Designing Animated Transitions to Convey Aggregate Operations
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Data can be aggregated in many ways before being visualized in charts, profoundly affecting what a chart conveys. Despite this importance, the type of aggregation is often communicated only via axis titles. In this paper, ...
Robust Extraction and Simplification of 2D Symmetric Tensor Field Topology
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
In this work, we propose a controlled simplification strategy for degenerated points in symmetric 2D tensor fields that is based on the topological notion of robustness. Robustness measures the structural stability of the ...
V-Awake: A Visual Analytics Approach for Correcting Sleep Predictions from Deep Learning Models
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
The usage of deep learning models for tagging input data has increased over the past years because of their accuracy and highperformance. A successful application is to score sleep stages. In this scenario, models are ...
Multiple Views: Different Meanings and Collocated Words
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We report on an in-depth corpus linguistic study on 'multiple views' terminology and word collocation. We take a broad interpretation of these terms, and explore the meaning and diversity of their use in visualisation ...
A User-based Visual Analytics Workflow for Exploratory Model Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Many visual analytics systems allow users to interact with machine learning models towards the goals of data exploration and insight generation on a given dataset. However, in some situations, insights may be less important ...
Topic Tomographies (TopTom): a Visual Approach to Distill Information From Media Streams
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
In this paper we present TopTom, a digital platform whose goal is to provide analytical and visual solutions for the exploration of a dynamic corpus of user-generated messages and media articles, with the aim of i) distilling ...
Interactive Volumetric Visual Analysis of Glycogen-derived Energy Absorption in Nanometric Brain Structures
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Digital acquisition and processing techniques are changing the way neuroscience investigation is carried out. Emerging applications range from statistical analysis on image stacks to complex connectomics visual analysis ...
Efficient Optimal Overlap Removal: Algorithms and Experiments
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Motivated by visualizing spatial data using proportional symbols, we study the following problem: given a set of overlapping squares of varying sizes, minimally displace the squares as to remove the overlap while maintaining ...
Dynamic Visibility-Driven Molecular Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Molecular surface representations are an important tool for the visual analysis of molecular structure and function. In this paper, we present a novel method for the visualization of dynamic molecular surfaces based on the ...
