We have the pleasure to present the second keynote speaker at VINCI 2018 Prof. Jon McCormack, Monash University, Australia on Design after Nature. You can find information on how to register for VINCI 2018 here

Abstract: Nature has driven us in what and how we create for millennia. Biomimetic approaches to human design are inspired by natural forms, shapes and processes. In computing, nature-inspired algorithms mimic collective behaviour or biological evolution to solve hard problems in search, optimisation and learning. In this talk I’ll show how I have developed a creative visual design practice informed by processes from biological development, the architecture of natural form, and evolutionary processes. My work began by devising advanced visual models of morphogenetic development in plants. Incorporating evolutionary processes allowed designs to emerge that would be difficult or impossible to discover independently, making them “beyond human design”. In later work, I have experimented with evolutionary ecosystems and processes such as niche construction to encourage diversity in the visual style of works generated by algorithmic processes. My most recent work looks at translating from the virtual back to the real, using digital fabrication technologies driven by generative computational processes. The goal is to build dynamic, responsive, intelligent physical systems that interact directly with living organisms, symbiotically affecting their growth and development. This leads to the creation of bio-machine hybrids – bringing the biomimetic concept full circle – and heralding a new form of co-design where human, machine and nature all contribute to the design process.

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

Wednesday, June 27th, 2018

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.

Short Bio: Min Chen developed his academic career in Wales between 1984 and 2011. He is currently the professor of scientific visualization at Oxford University and a fellow of Pembroke College. His research interests include visualization, computer graphics, human-computer interaction, and aspects of computer vision. He has co-authored some 200 publications, including his recent contributions in areas such as theory of visualization, video visualization, visual analytics, and perception and cognition in visualization. He has worked on a broad spectrum of interdisciplinary research topics, ranging from the sciences to sports, and from digital humanities to cybersecurity. His services to the research community include papers co-chair of IEEE Visualization 2007 and 2008, Eurographics 2011, IEEE VAST 2014 and 2015; co-chair of Volume Graphics 1999 and 2006, EuroVis 2014; associate editor-in-chief of IEEE Transactions on Visualization and Computer Graphics; and co-director of Wales Research Institute of Visual Computing.

Invited journal article presentation at ACM IUI 2018 in Tokyo

Friday, March 23rd, 2018

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

Tuesday, October 17th, 2017

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

Wednesday, August 30th, 2017

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.

Monday, August 14th, 2017

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.
