KvarkenSat Innovation Challenge 2022 on Sustainable Forestry

Thursday, February 10th, 2022

The DISA forestry group invites you to KvarkenSat Innovation Challenge 2022 on Sustainable Forestry that will start in next week with a pre-hackathon followed by the hackathon using space-based data helping to combat climate change!

Acceptance based on submission, the best submissions may be approved early.

The challenges

Climate change brings about major changes affecting us all. Extreme weather events become more frequent and especially the amount of rainfall increases in Northern Europe, one contributor being the warmer winters. New species of both vegetation and animals enter new areas while the existing species might have even major changes in their habitats. These lead to new challenges in the forestry industry. We are looking for ideas and solutions combining existing knowledge and datasets with space-based data and datasets based on satellite measurements, in four particular themes including soil moisture, spruce bark beetles, forest ground damage and the forest value chain.

Who can apply?

The hackathon is open to students, teachers, researchers and start-ups in teams of 3-5 persons. Relevant expertise to participate include: space and satellite data, machine learning and neural networks, computer science, positioning systems, automation, image processing/recognition, engineering, logistics, business/communications and forestry.

Awards

The three best proposals across all of the themes will be awarded a cash prize (over 100 000SEK) and possible continuation/acceleration within start-ups and innovation programs.

Pre-Hack Webinar

To get familiar with the hackathon, meet the mentors and partners, and participate in Q&A-session join our webinar on 15 February at 13.00 (14.00 Finnish time).

DISA Seminar November 1st on Visualization Perspectives in Explainable AI

Thursday, October 14th, 2021
  • When? November 1st, 2021 at 12-13
  • Where? Online, links will be sent to those registered
  • Registration via this link

This talk with Professor Andreas Kerren, will overview interactive data visualization research with a focus on the development and use of visualization techniques for explainable artificial intelligence. The field of Information Visualization (InfoVis) uses interactive visualization techniques to help people understand and analyze data. It centers on abstract data without spatial correspondences; that is, usually it is not possible to map this information directly to the physical world. This data is typically inherently discrete. The related field of Visual Analytics (VA) focuses on the analytical reasoning of typically large and complex (often heterogeneous) data sets and combines techniques from interactive visualizations with computational analysis methods. I will show how these two fields belong together and highlight their potential to efficiently analyze data and Machine Learning (ML) models with diverse applications in the context of data-intensive sciences. As ML models are considered as complex and their internal operations are mostly hidden in black boxes, it becomes difficult for model developers but also for analysts to assess and trust their results. Moreover, choosing appropriate ML algorithms or setting hyperparameters are further challenges where the human in the loop is necessary. I will exemplify solutions of some of these challenges with the help of a selection of visualization showcases recently developed by my research groups. These visual analytics examples range from the visual exploration of the most performant and most diverse models for the creation of stacking ensembles (i.e., multiple classifier systems) to ideas of making the black boxes of complex dimensionality reduction techniques more transparent in order to increase the trust into their results.

Research seminar (PhD) – Nico Reski, Wed18Sep, 16:00, D1136V

Tuesday, August 27th, 2019

Nico Reski will present the progress of his doctoral studies in Computer and Information Science so far, and the work we have been conducting at the VRxAR Labs research group. This involves topics such as virtual reality, 3D user interfaces, immersive analytics, and computer-supported cooperative work. During the second part of the seminar I am looking forward to have a discussion with the audience regarding feedback and future directions of this work.

A warm welcome, no registration in advance is needed

Second Keynote speaker at VINCI 2018 is Keynote Speech 2: Design after Nature Prof. Jon McCormack, Monash University, Australia

Friday, June 29th, 2018

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.
