Welcome to the Higher Research Seminar in Computer Science on April 21st

Thursday, April 6th, 2023

Professor Mauro Caporuscio will give a seminar on April 21st 14-15 at Linnaeus University about Green Software by Design. It is possible to attend the seminar either onsite or online. If you are interested in joining please send an email to

Despite the media interest in sustainability, the public is still unaware that software, including digital assistants, cryptocurrencies, audio/video streaming services, finances, and games, are predicted to account for as much as 14% of the total worldwide carbon footprint in the next decade. Indeed, all software consumes electricity. In general, people think electricity is clean. Still, since most electricity is produced through burning fossil fuels (e.g., coal, oil, and natural gas), in practice, electricity is the single most significant cause of carbon emissions worldwide. Further, all the devices we use for running software (from our smartphones/computers to network appliances, and to cloud infrastructures) produce carbon when manufactured and disposed of (once they reach the end of life). The two most effective ways to reduce the carbon emissions of software are through Energy efficiency, and Hardware longevity. Unfortunately, current software development projects usually treat these concerns as an afterthought: a desirable quality to be considered if and only if other stakeholder- and economy-centered requirements (e.g., performance, business needs) have been successfully addressed. To face this unsustainable trend, we need a paradigm shift in the way we engineer and operate software systems. Indeed, the software shall be designed from the foundation to be green.

The aim of this talk is to bring these aspects to your attention and to hint at future research directions toward the reconciliation of three different and typically conflicting aspects: (1) efficiency: the ability to limit energy consumption, (2) longevity: the ability to live long and prevent hardware obsolescence, and (3) efficacy: the ability to meet the users’ expectations.

First publication from our Industry PhD-students at Volvo CE is published!

Wednesday, March 8th, 2023

Volvo CE is a major player in the construction business and leads the development of machines and technologies for sustainability, autonomy, and connectivity. An enabler for this technology transformation is smart usage and integration of machine operation data and computer simulations. To increase the knowledge in Volvo CE, a cooperation with the Linnaeus University started and Manoranjan Kumar and Joel Cramsky became two of the first industry PhD-students in DIA.

Something that most developers in industry do not do in their daily work is to share their knowledge in publications, but it’s an important part during the PhD-studies. One part of these studies has led to a paper within Data Science, “A prediction model for exhaust gas regeneration(EGR) clogging using offline and online machine learning” and it was recently published as a part of the Conference Proceedings of the 7th International Commercial Vehicle Technology Symposium.

Visual Analytics for Explainable Machine Learning in a Nutshell – Angelos Chatzimparmpas

Machine learning (ML) research has recently gained much attention, with various models proposed to understand and predict patterns and trends in data originating from various domains. Unfortunately, users find it harder to evaluate and trust the results of these models as they become more complex because most of their internal workings are kept in secret black boxes.

One possible solution to this problem is the explanation of ML models with visual analytics (VA) since it enables human experts to analyze large and complex information spaces such as data and model spaces. By doing so, evidence has shown an improvement in predictions and an increase in the reliability of the results.

This talk aims to provide an overview of the state-of-the-art in explainable and trustworthy ML with the use of visualizations, as well as the development of VA systems for each stage of a typical ML pipeline. Furthermore, we will briefly introduce some of these tools and discuss how such VA techniques can help us not only understand ML models but also do this in a human-centered and steerable way.

Getting the most out of health data, combing the best of two worlds – Olle Björneld

Machine learning driven knowledge discovery on real world data based on domain knowledge. Real world data does not comply with machine learning models very well and prediction models perform suboptimal if pre-processing of data is deficient.

Based on experience from medical registry studies using electronic health data (EHR) performed in collaboration with domain experts, data analyst and statistician an automatic feature engineering framework and method have been developed. The framework is called automatic Knowledge Driven Feature Engineering (aKDFE) and have been evaluated by machine learning pipeline.

Experiment shows that prediction models performs better if aKDFE is used without losing explainability, but more experiments need to be performed in other domains to fully quantify the results. The key aspect is how to concentrate and mine inherent knowledge in transaction data to optimal machine learning driven prediction models.

A warm welcome,

Welf & Diana

New PhD-seminar series in Computer Science

Saturday, October 1st, 2022

In Computer Science at Linnaeus University we have different types of PhD-students. Our regular PhD-students, DISA-PhD-students and DIA-PhD-students and will hopefully be approved of getting a second intake for DIA starting next semester. Our PhD-students do not regularly meet these days and we want to change this. This will be an opportunity for PhD-students, supervisors from the university and industry to meet and discuss and provide a structured knowledge exchange.

We are working to increase the quality and formal processes for all of our PhD-students and as a first step we will introduce monthly PhD-seminars starting beginning of November 2022.

We will meet first Friday of each month between 14-16 preferably onsite but if it’s not possible we will provide the possibility to connect online too. During each seminar 2 PhD-students will get the chance to present their research and status for 30 min followed by a Q& A for 20-25 min with a coffee break in between.

Keep your eyes open for more information

  • When? April 4th, 2022 12-13
  • Where? Online, you will get a link to the event when you have registered
  • Registration:

DISA welcomes you to an information seminar focused on information and advice on how to develop a competitive proposal in the upcoming call for Marie Skłodowska Curie postdoctoral fellowships (MSCA-PF). The seminar will include presentations illustrating four relevant perspectives – key information, evaluation of proposals, hosting an MSCA-PF fellow and being an MSCA-PF fellow. As a fellow you apply for the fellowship with a PI, and as a PI you apply for the fellowship with an identified fellow. The seminar will provide researchers interested in becoming a supervisor for a MSCA PF with information on the fellowship programme, the requirements of a supervisor, practical information, and insights on how to write a competitive proposal from the supervisor’s perspective.

The MSCA PF tool is an outstanding prospect to expand your research group by an extremely skilled and funded postdoctoral researcher for two years while adding complementary skills and competencies to your group.


From the programme:

  • What is MSCA Postdoctoral Fellowships?
  • Proposal writing process
  • What is required from you as a Supervisor? The MSCA Guidelines on Supervision.
  • LNU as a host institution
  • Yes, I want to be a MSCA supervisor. What do I do now?
  • Experiences from a LNU MSCA PF Supervisor
  • Q&A


The objective of the Horizon Europe MSCA-PFs is to support researchers’ careers and foster excellence in research. The Postdoctoral Fellowship’s action targets researchers holding a PhD who wish to carry out their research activities abroad, acquire new skills and develop their careers. PF grants help researchers gain experience in other countries, disciplines and non-academic sectors. The grant usually covers two years’ salary, a mobility allowance, research costs and overheads for the host institution. Applications should be co-written by the researcher and the host organization. MSCA PF is open to all scientific disciplines.

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.


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).
