KvarkenSat Innovation Challenge 2022 on Sustainable Forestry

2022-02-10

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!

Date: 18.03 – 20.03.2022 (see also information about the Pre-Hack Webinar on 15.02.2022 below)
Where: Online
Application deadline: Deadline: 10.03
Apply here: https://ultrahack.org/kvarkensat-innovation-challenge-2022

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 February 7th: Using social media data to increase political participation in semi-authoritarian regimes

2022-01-12

When? February 7th, 2021 at 12-13
Where? Online, links will be sent to those registered
Registration via https://forms.gle/5WmcTndj3YnHQyCq5

During our first DISA seminar for 2022 we will listen to Elizaveta Kopacheva, PhD student in Political Science and a part of the DISA group for Computational Social Sciences

Abstract:

Previously, the importance of weak ties, no ties and periphery nodes was reported in the context of political information diffusion. Yet, earlier studies did not focus on the primary role of weak/no ties in mobilization into low-cost political activities. Moreover, examining the importance of such ties, previous research solemnly relied on the surveys.

Low-cost participation is often the only resort to influence decision-making in societies with underdeveloped democratic values and fragmented civil society (e.g., the Russian society). In that regard, it is essential to examine successful mobilization strategies that increase participation in low-cost activities.

In this talk, I will show how using social media data, we can analyze the patterns of increased participation in e-petitioning, as an example of low-cost political participation.

By assessing mobilization strategies carried out on two social networking sites, i.e., VKontakte characterized by the presence of strong ties and Twitter where communication takes place via weak ties or no ties, one can compare the effects of strong vs. weak/no ties on e-petitioning.

Moreover, examining participation in semi-authoritarian regimes, one must consider the costs of participation in unconventional activities (such as petitioning, protesting, etc.). To control for the constraints of political mobilization related to the costs of participation, in my study, I compared participation on the two biggest e-petitioning platforms in Russia, i.e., Russian public initiative and Change.org.

The results of my study showed that “information” mobilization via weak/no ties is the most important step for successful recruitment into low-cost political activities. At the same time, poorly designed e-governance services substantially increase the cost of participation, thus, the need for persuasion and social support via strong ties.

Linear regression with interaction effects and Bayesian network analyses are applied to test for the significance of the “information”, “persuasion” and “social support” effects on the petition-signing.

Key words: social media, successful mobilization, recruitment, political information, weak ties, Russia, e-petitioning, low-cost participation

Seminar October 18th – Future Position X

2021-10-01

When? Monday October 18th 12-13
Where? Online, link will be sent to those who sign up via this link https://forms.gle/NTo7jnysyLkBWaAm8 no later than October 15th

During the seminar Magnus Engström, CTO at Future Position X (FPX) will talk about two clear cases where FPX with data science has contributed to creating the conditions for a viable city center by collecting and combining data from different sources. More specifically, it will be about how we have applied machine learning to be able to predict movements in the city center and how we with a data-driven approach have created an application that helps the University of Gävle to conduct research on how Gävle residents experience their local environment. The presentation will be followed by a Q&A and discussion about potential collaborations with researchers from Linneaus University

Future Position X is an independent Swedish innovation center that works for growth through better health and well-being in the smart, sustainable and vibrant city. FPX contributes both technology and expertise to develop data-driven community solutions.

By initiating projects, creating relationships and building collaborations, FPX contributes to collaboration between business, academia and the public sector. FPX contributes to knowledge development of new technology by creating meeting places and networks around data-driven innovation such as GIS, AI, Internet of Things and blockchain technology. FPX also provides technical solutions, including the Innovation Platform, a data platform that can be used to digitally model societies. We are an important player in the work of strengthening both society and companies to a more sustainable growth.

Workshop “Critical perspectives on cultural heritage: Re-visiting digitisation” 26 October, 9-12hrs

2021-09-28

Where: https://lnu-se.zoom.us/j/63272495423
When: 26 October, 9-12hrs

Organizers: The workshop is co-organized by Linnaeus University (Centre for Applied Heritage and iInstitute) and Swedish National Heritage Board

Website: https://lnu.se/en/meet-linnaeus-university/current/events/2021/critical-perspectives-on-cultural-heritage-re-visiting-digitisation/

About: Today, the Semantic Web and Linked Open Data are creating new value for the descriptive information in the cultural heritage sector. Libraries, museums, heritage management and archives are seeing new possibilities in sharing by turning their catalogues into open datasets that can be directly accessed, allowing cultural heritage data to be circulated, navigated, analyzed and re-arranged at unprecedented levels. This is supported by research funding bodies, governments and EU policies and numerous political interests, resulting in enormous investment in digitization projects which make cultural heritage information openly available and machine readable. But before deploying this data, one must ask: is this data fit for deployment?

Libraries, museums, heritage management and archives have long histories. Both the collections they house and the language they use(d) to describe said collections are products of that historical legacy, shaped by, amongst others, institutionalized colonialism, racism and patriarchy. Yet descriptive information is now being digitized and shared as if that legacy is not inherent to the collections. Instead, existing units of information are being distributed through new Web 3.0 technologies, bringing with it an outdated knowledge-base. Besides the risk of progressive techniques being applied to regressive content, we may also sacrifice the development of new knowledge in libraries, museums, heritage management and archives aimed at facilitating socially sustainable futures, remediating exploitative historical legacies.

For this workshop, we have invited researchers and practitioners to discuss ways in which digitisation approaches may be set up to change the nature and legacy of cultural collection prior to digital dissemination.

DISA Seminar October 4th on Aggregation as Unsupervised Learning and some of its Applications

2021-09-24

When? October 4th 12-13
Where? Online – the link will be sent to those who sign up
Registration? Sign up via this link no later than October 3rd.

This seminar will be presented by the DISTA research group within DISA, you will meet and listen to Welf Löwe, Maria Ulan, Morgan Ericsson, Anna Wingkvist

Aggregation combines several independent variables to a dependent variable. The independent variables are different, possible mutually dependent observations of a real world. The dependent variable should preserve properties of the independent variables, e.g., the ranking or relative distance of the independent variable tuples, and ultimately the properties of the real world. However, while there usually exist large amounts independent variable tuples, there is no ground truth data available mapping these tuples to the corresponding dependent variable values. This makes aggregation an unsupervised machine learning problem, as opposed to, e.g., regression where data comprises independent variable tuples and the corresponding dependent variable values.

Instances of the problem frequently occur in software engineering, e.g., when trying to assess the quality of software by metrics. Metrics (independent variables) can easily be measured for a lot of software artifacts, but it is hard to measure quality (dependent variable). Instances also occur in many other assessment situations including, but not limited to the assessment of project proposals, financial investments, and human movements.

In our talk, we present
1) aggregation as unsupervised learning including unweighted and weighted approaches
2) ways to evaluate and compare different aggregation approaches including an evaluation of the approaches introduced in 1)
3) applications to software engineering problems applying the evaluation introduce in 2)

iInstitute / Digital Humanities webinar: The Ethics of Datafication and AI by Geoffrey Rockwell

2021-05-18

Summary – We all want artificial intelligence to be responsible, trustworthy, and good… the question is how to get beyond principles and check lists. In this paper I will argue for the importance of the data used in training machines, especially when it comes to avoiding bias. Further, I will argue that there is a role for humanists and others who have been concerned with the datafication of the cultural record for some time. Not only have we traditionally been concerned with social, political and ethical issues, but we have developed practices around the curation of the cultural record. We need to ask about the ethics around big data and the creation of training sets. We need to advocate for an ethic of care and repair when it comes to digital archives that can have cascading impact.

Speaker: Geoffrey Rockwell
Title: The Ethics of Datafication and AI
Time: May 26 (Wednesday), 16:00-17:00
Location: https://lnu-se.zoom.us/j/6246053108
