Prof. Min Chen, University of Oxford, UK, first keynote speaker at VINCI 2018

2018-06-27

We have the pleasure to present the first keynote speech at VINCI 2018 : Is Visualization Underpinned by Communication Theory? held by Prof. Min Chen from University of Oxford, UK. You can find information on how to register for VINCI 2018 here

Abstract: Seven decades ago, Claude Shannon’s landmark article “A Mathematical Theory of Communication” (1948) laid down the foundation of modern tele- and data communication, giving rise to information theory as an academic subject. In this talk, the speaker will describe the applications of information theory to visualization and demonstrate how information theory can explain numerous phenomena in visualization. In particular, the speaker will discuss an information-theoretic metric for analysing the cost-benefit of data intelligence workflows, elaborating the values of visualization in such workflows. The speaker will also outline conjectures that the metric may potentially have implications beyond data science.

Visual communication through graphics or text has long been conducted among human beings of different backgrounds or cultures, and in recent decades between human and machine. In today’s digital world, visual information is typically encoded with various metaphors commonly used in daily life to facilitate rapid comprehension and easy analysis during the communication process. Visual information communication generally encompasses information visualization, graphical user-interfaces, visual analytics, and visual languages. Visual information is increasingly being used to facilitate human-human communication through the Internet and mobile devices.

The Symposium on Visual Information Communication and Interaction (VINCI) (vinci-conf.org) is the premier international forum for researchers and industrial practitioners to discuss the state-of-the-art in visual communication theories, designs, and applications. The 11th International Symposium on Visual Information Communication and Interaction (VINCI ’18) will be held on 13-15 August 2018, in Växjö, Sweden.

Invited journal article presentation at ACM IUI 2018 in Tokyo

2018-03-23

A journal article titled “Active Learning and Visual Analytics for Stance Classification with ALVA“, co-authored by a DISA researcher Andreas Kerren, was invited for a presentation at the ACM IUI 2018 conference which took place in the National Center of Sciences Building, Tokyo, Japan during March 7–11, 2018. The article was presented by Kostiantyn Kucher, a PhD student in Computer Science with the ISOVIS group at Linnaeus University.

ACM IUI 2018 was the 23rd annual meeting of the intelligent interfaces community, where novel top-quality contributions in human-computer interaction, information visualization, artificial intelligence, and machine learning were presented. The main topics of interest during the conference seemed to be interactive machine learning (iML) and user interfaces for explainable artificial intelligence (XAI).

Our article presented at IUI is very much relevant to these topics: it describes a visual analytics environment ALVA that is designed for annotation of textual data, management of an active learning classifier, and visual analysis of the intermediate data. ALVA was previously developed as part of the finished VR-funded StaViCTA project for stance analysis of social media texts, and we plan to adapt and apply it for future tasks in DISA research.

Visualization focus in Phoenix, Arizona

2017-10-17

During October 1-6, 2017 Andreas Kerren, professor and Rafael Martins, Post-doc in Computer Science at Linnaeus University attended the IEEE VIS Conference in Phoenix, Arizona. IEEE VIS is the absolute top-level conference in the area of Visualization and this year they had, state-of-the-art presentations from the biggest names in the field.

During the conference Rafael Martins presented a paper at a co-located workshop, the 2nd Workshop on Visualization for the Digital Humanities (VIS4DH). The purpose of the workshop was to propose new research directions in visualization for the digital humanities, to familiarize the visualization research community with the problems faced by digital humanities researchers, and to foster future collaboration between visualization and digital humanities research.The paper presented by Rafael Martin is entitled StanceXplore Visualization for the Interactive Exploration of Stance in Social Media

The conference had a very strong focus on the combination of Machine Learning (ML) and Visualization, both from the perspective of interactive steering of ML techniques and also explaining the inner workings of complex techniques such as Deep Learning. There was also a lot of discussion about Visualization literacy, meaning, how people understand Visualization and how to improve on this.

Overall the conference was productive and full of interesting and diverse work and we are looking forward to see how the new insights can become valuable in from a DISA-perspective.

 

MemAxes: Visualization and Analytics for Characterizing Complex Memory Performance Behaviors

2017-08-30

A new publication in the journal: IEEE Transactions on Visualization and Computer Graphics by our senior lecturer Ilir Jusufi about High-Performance Computing memory performance analysis through the use of Visual Analytics.

Abstract: Memory performance is often a major bottleneck for high-performance computing (HPC) applications. Deepening memory hierarchies, complex memory management, and non-uniform access times have made memory performance behavior difficult to characterize, and users require novel, sophisticated tools to analyze and optimize this aspect of their codes. Existing tools target only specific factors of memory performance, such as hardware layout, allocations, or access instructions. However, today’s tools do not suffice to characterize the complex relationships between these factors. Further, they require advanced expertise to be used effectively. We present MemAxes, a tool based on a novel approach for analytic-driven visualization of memory performance data. MemAxes uniquely allows users to analyze the different aspects related to memory performance by providing multiple visual contexts for a centralized dataset. We define mappings of sampled memory access data to new and existing visual metaphors, each of which enabling a user to perform different analysis tasks. We present methods to guide user interaction by scoring subsets of the data based on known performance problems. This scoring is used to provide visual cues and automatically extract clusters of interest. We designed MemAxes in collaboration with experts in HPC and demonstrate its effectiveness in case studies.

New research opportunities with Södra.

2017-08-14

During late spring 2017, guest researcher Andreas Heberle spent some weeks to learn more about the needs and opportunities for joint research between Södra and tour DISA researchers. During these months Andreas has interviewed several domain experts at Södra and he found over 50 ideas and opportunities that could be the base for joint research.

Just before the summer holidays started, DISA researchers and experts from Södra gathered for a follow up workshop to discuss the potential next steps. The experts from Södra got the list with 50 ideas down to seven that were the most prioritized for them and in discussion with the researchers the list went down to three ideas/opportunities. Many of the other ideas will be taken care of internally at Södra. We have responsible people for each idea and looking forward to see some concrete action, either as full research projects or as student projects in one form or another.

We will by this show that there are many different ways to work together and it is by talking we can find out what works best for us within DISA and for you who wants to work closer with us. If you have ideas for joint research – don’t hesitate to contact us.
