Clinical signals and theoretical insights: Exploring the principles and practice of AI 

Thomas Schön, Uppsala University, Sweden

Session chair: Jonas Unger (LiU)

Abstract
Abstract: In this talk, I will explore how deep learning is transforming both clinical practice and fundamental research. We begin in the emergency room, where electrocardiograms (ECGs) are used to diagnose cardiovascular diseases. By leveraging large-scale clinical datasets, we show that deep neural networks can achieve good diagnostic performance—highlighting the power of data-driven medicine. In the second half, I shift focus to three core research areas that have emerged from our work in healthcare. First, I’ll introduce diffusion models and demonstrate their versatility across a few different computer vision tasks. Second, we will examine the challenge of using deep learning to solve regression problems, and how energy-based models offer promising solutions. Finally, I’ll touch on adversarial training and its role in building more robust AI systems. The talk is structured to reflect my broader philosophy: that research often arises from the interplay between real-world applications and foundational scientific inquiry.

Learning for Control—and Back Again
Farnaz Adib Yaghmaie (LiU)

Abstract

Artificial Intelligence and Machine Learning have become deeply embedded in our daily lives, often in ways we don’t even notice. Their growing presence has sparked significant interest in applying learning-based methods to control and dynamical systems, especially in the face of uncertainty, noise, and incomplete models. In such settings, learning from expert demonstrations and data-driven approaches can play a crucial role. Interestingly, many learning algorithms themselves can be viewed as dynamical systems, particularly when they involve iterative updates like gradient descent. This perspective opens the door to applying well-established tools from control theory to analyze and improve learning algorithms. In this talk, I will present recent work on developing learning-based solutions for control systems, and explore how viewing learning algorithms as dynamical systems can offer new insights and opportunities for cross-disciplinary innovation.

Active Personas for Continuous Validation in Digital Business
Henry Edison (BTH)

Abstract

In digital business, software products must meet diverse and evolving user needs, yet traditional feedback methods like interviews and surveys often prove too slow for agile development cycles. We introduce Active Persona (AP), an AI-based, dynamic user archetype that provides realistic and contextual feedback on demand. By transforming static personas into interactive generative agents, APs enable continuous validation and user-centric experimentation throughout the development process. Our evaluation using a mobile transport app reveals that APs produce insights closely aligned with actual users, identifying the same usability and accessibility issues. These findings demonstrate how APs can accelerate innovation cycles while enhancing user understanding and optimizing resource allocation in digital business environments.

From Dense to Sparse: Exploiting Network Structure in Control System Design
Richard Pates (LU)

Abstract

Classical optimal control and estimation techniques can deliver high levels of robust performance, but their practical use in large-scale systems is hindered by dense communication demands. This talk explores how we can implement dense optimal controllers and estimators in a sparse and scalable way. Using ideas from sparse linear algebra, we aim to preserve optimality while drastically reducing the need for all-to-all communication. We illustrate the approach by showing how a simple message passing algorithm can be used to optimally regulate transportation networks.

Of mice and men

Kathryn Hess Bellwald, École Polytechnique Fédérale de Lausanne, Switzerland

Session chair: Ingrid Hotz (LiU)

Abstract
Motivated by the desire to automate classification of neuron morphologies, we designed a topological signature, the Topological Morphology Descriptor (TMD),  that assigns a “barcode” to any any finite binary tree embedded in R^3. Using the TMD we performed an objective, stable classification of pyramidal cells in the rat neocortex, based only on the shape of their dendrites.
In this talk, I will introduce the TMD, then focus on a very recent application to comparing mouse and human cortical neurons and characterizing the differences between them, in particular in terms of the networks they form. This talk is based on a longterm collaboration led by Lida Kanari.

Tracking a Moving Target: Quality Assurance in Continuous Software Engineering
Emelie Engström (LU)

Abstract

As software systems grow more complex and development moves faster, ensuring software quality remains both a critical challenge and a moving target. Continuous integration and delivery practices, coupled with the integration of AI components, both in the systems we build and in the tools we use to build them, have transformed traditional quality assurance (QA) approaches. This talk shares insights from our collaborative research efforts to address this challenge.

From Optimal Vehicle Maneuvers to Context-Aware Prediction and Planning in Autonomous Vehicles: An ELLIIT Collaboration
Björn Olofsson (LU & LiU)

Abstract

Autonomous vehicle maneuvering has the potential to significantly improve both traffic safety and transportation efficiency. When the ELLIIT research collaboration on optimal vehicle maneuvers between Dept. Automatic Control (LU) and Div. Vehicular Systems (LiU) was initiated 15 years ago, a key motivation was the increased situational awareness enabled by onboard sensing systems, which opened entirely new possibilities for autonomous control functions. Drawing inspiration from numerical solutions to dynamic optimization problems of relevant maneuvers, led to the development of control principles and real-time architectures for vehicle maneuvering. To address uncertainties in future motion of surrounding vehicles in multi-vehicle scenarios, context awareness is a key feature of the motion prediction and planning. This talk will highlight both the results of this collaboration and aspects of how it was established and developed.
