ProxiLens: Interactive Exploration of High-Dimensional Data using Projections
(The Eurographics Association, 2013)
As dimensionality increases, analysts are faced with difficult problems to make sense of their data. In exploratory data analysis, multidimensional scaling projections can help analyst to discover patterns by identifying ...
Attribute-based Visual Explanation of Multidimensional Projections
(The Eurographics Association, 2015)
Multidimensional projections (MPs) are key tools for the analysis of multidimensional data. MPs reduce data dimensionality while keeping the original distance structure in the low-dimensional output space, typically shown ...
Visual Analysis of Relations in Attributed Time-Series Data
(The Eurographics Association, 2015)
In this paper, we present visual-interactive techniques for revealing relations between two co-existing multivariate feature spaces. Such data is generated, for example, by sensor networks characterized by a set of ...
Using User-Centered Techniques for the Design and Evaluation of Interactive Visualizations to Support Urban and Regional Planning: Case Study Bogota 21
(The Eurographics Association, 2013)
User-centered techniques and evaluations are very important for the design of interactive visualizations. We applied the UCIV4 Planning Approach (User-Centered Interactive Visualizations for Planning) within the project ...
User-Assisted Disparity Maps
(The Eurographics Association, 2012)
In this paper, we present an intuitive and efficient system for correcting the artifacts and noises caused by imperfect disparity estimation. Disparity estimation is a very important and basic process for almost all ...
A Novel Radial Visualization Approach for Undirected Hypergraphs
(The Eurographics Association, 2013)
Hypergraphs are a more generalized concept of graphs where an edge typically connects multiple vertices. They are applicable to many different domains such as the representation of complex biochemical pathways or classification ...
Visual Analytics for Exploring Changes in Biodiversity
(The Eurographics Association, 2013)
We report on ongoing work in which we are designing a visual interface to a large database of species observation data. Our design allows the data to be explored and visually summarised by space, time and species, helping ...
Utilizing GeoTemCo for Visualizing Environmental Data
(The Eurographics Association, 2014)
We demonstrate the use of the open source library GeoTemCo for the visualization and exploration of geospatialtemporal datasets from environmental sciences. With use cases from biodiversity, climatology and geophysics we ...
A Visual Analytics Field Experiment to Evaluate Alternative Visualizations for Cyber Security Applications
(The Eurographics Association, 2014)
The analysis and exploration of emerging threats in the Internet is important to better understand the behaviour of attackers and develop new methods to enhance cyber security. Fully automated algorithms alone are often ...
Towards more Visual Analytics in Learning Analytics
(The Eurographics Association, 2014)
Learning Analytics is the collection, management and analysis of students' learning. It is used to enable teachers to understand how their students are progressing and for learners to ascertain how well they are performing. ...
