The guest program within ELLIIT has the goal to unite high-level international researchers and inspire young ELLIIT researchers through personal contacts with top international researchers.  The most important instrument for the ELLIIT guest program is the 5-week focus period, organized twice a year at one of the ELLIIT universities. We strive to create an environment where ELLIIT researchers can work under optimal circumstances in collaboration with other internationally established scientists around a specific research topic. Researchers within ELLIIT are always welcome to contact us to discuss topics for upcoming focus periods.

ELLIIT is now inviting proposals by potential organizers willing to host focus periods in the spring or autumn of 2026. Submit your propsal by November 17, 2024.

Spring 2025 – Linköping (Campus Norrköping)

Visualization-Empowered Human-in-the-
Loop Artificial Intelligence

In the past years, experts in visualization, human-computer interaction and related fields have substantially contributed to the topic, for instance, by the development of visualization approaches to open the typically closed black box design of popular machine learning methods. However, the rapid developments in AI/ML potentially trigger a fundamental change in our understanding of the capabilities and applicability of the models as they are now also able to “interact” with the general population. What are the implications in terms of trust into the analytical results and potential biases that may occur? How should visualization research react and adapt to increase trust and call our attention to critical biases to avoid them?

The purpose of the focus period is to discuss the aforementioned topic in depth and over a longer period of time. The focus period will run at Linköping University, Campus Norrköping between April 28 and May 30, 2025. A number of international scholars interested in these research challenges will be invited to participate, and to interact with leading scientists as well as ELLIIT researchers.

In the third week (May 13-15) we will have a 3-day symposium in the city of Norrköping close to our beautiful Campus Norrköping with several invited top-level researchers.

Machine Learning for Climate Science

Climate change is a complex and urgent problem that requires accurate and reliable models of the Earth’s climate systems. These models can help us understand the causes and consequences of climate change, and to evaluate the effectiveness of different policies and actions. Traditionally, mechanistic models have been used for this purpose. However, the Earth’s climate systems are extremely complex and these models are inevitably oversimplifying. For many highly critical use cases, in particular involving local events such as accurately predicting flooding, heatwaves, and storm surges, existing models need to be improved. At the same time, today we have access to a plethora of data from multiple dense networks of ground-based monitoring stations as well as both passively and actively remote-sensed data from drones, aircraft, and satellites. We are therefore seeing and increasing interest in using machine learning for improving and complementing the traditional modeling approaches. Machine learning can help us discover new patterns and relationships in the data, improve the accuracy and speed of the simulations, and result in better uncertainty quantification.

The purpose of this focus period was to bring together researchers who share an interest in machine learning for climate science in general, and machine-learning-augmented modeling and analysis of climate and weather systems in particular, to lay the foundation for novel research on how machine learning can be used to address critical problems in climate science currently lacking satisfactory solutions.

The focus period will run in Linköping between September 23 and October 25, 2024. A number of international scholars interested in these research challenges will be invited to participate, and to interact with leading scientists as well as ELLIIT researchers. In the third week (October 8-10) there will be a 3-day symposium, with several invited top-level researchers.

Spring 2024 – Lund

Security and Fault Tolerance of Cyber-Physical Systems

In this focus period, the organizers wanted to plant the seed for a radical rethinking of the way cyber-physical systems are constructed, questioning their fundamental principles and striving for constructions that are secure, safe, controllable, and dependable from the beginning.

The focus period ran in Lund between April 1 and May 3, 2024.

Fall 2023 – Lund

6G – forming a better future

Research related to the 6th Generation Wireless Systems (6G) comprises a wide range of topics. This focus period takes a broad perspective on the possibilities and limitations of technology available and what services and applications can be proivided by a future 6G system. Topics range from communication theory and fundamental limits via practical implementations to novel services and applications.The goal is to close the gaps between different research disciplines, increase synergy effects and, together, identify the most critical inter/intra-disciplinary research challenges, from a 6G perspective. What are the technical issues we have to address, from that perspective? What are the possible solutions, from a technical perspective? How should 6G be designed to, in the best way, contribute to solving of the global challenges?

The focus period ran in Lund between October 23rd and November 24th.

Fall 2023 – Linköping

Networks Dynamics and Control

A central task in Network Science is to understand how to extrapolate emerging collective dynamical behaviors out of a large number of interacting elementary entities. An even more challenging task is to move from a passive observation of the behavior of a network to an active way of controlling its dynamics. Both tasks require a system-level thinking, and can have profound repercussions across the many different domains of science in which networks are of relevance, such as biology, ecology, social sciences, economical sciences, and engineering.

The aim of this 5-week focus period was to stimulate the interaction between scientists working on network dynamics and control from different perspectives, and to favour cross-talk by promoting awareness of what is available “next door”.

The focus period took place in Linköping between September 4th and October 6th.

Fall 2022 – Linköping

Hybrid AI – Where data-driven and model-based methods meet

Data-driven machine learning presents many challenges such as how to deal abstract and causal aspects, how to make learning work with significantly less data like humans can do, and how to achieve robust systems which provides formal guarantees and interpretability. Traditional model- or knowledge-based methods are designed to deal with many of these issues: They deal effectively with generality, abstraction, and causality with strong formal guarantees. A current trend in AI and machine learning today is therefore how to combine these different approaches in a principled and effective way. This is often called Hybrid AI.

The full focus period spanned October 18 – November 18, 2022.

Spring 2022 – Lund

Data-driven modelling and learning for cancer immunotherapy

Checkpoint inhibitor therapy is a form of cancer treatment that works tremendously well in approximately 30 % of subjects, while being largely ineffective in others. Understanding when and why the therapy works has large implications on the treatment of cancer. In spring 2022, the first ELLIIT focus period will look deeper into this challenge.

For 5 weeks, in the prestigious university town Lund, the focus period united young international scholars, ELLIIT researchers and other top international academics active in domains such as:

  • Systems biology
  • Cancer treatment
  • Checkpoint inhibitor therapy
  • Machine learning
  • Dynamical systems
  • Deep learning

During this period, the researchers worked together on jointly defined research topics. In addition to seminars and joint research challenges using unique data sets, a larger workshop with invited top-level scientists provided knowledge exchange and networking opportunities. The aim of the focus period was to forge new, long lasting, collaborations based on life science research that use and drive the development of novel machine learning techniques.

The full focus period spaned April 19 – May 20, 2022.
