Title
Explaining AI: helpful, harmful, or just hype?
Visualization-Empowered Human-in-the-Loop Artificial Intelligence
Abstract
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?

Title
Machine- or Human-centered Visual Analytics: Do we Still need Humans for Data Analysis?
Abstract
In response to the 2001 terrorist attacks in the United States, a research and development agenda was established to develop a new discipline that supports analytical reasoning for large databases, facilitated by interactive visual interfaces. So, Visual Analytics was born. As initially defined, Visual Analytics is the process where humans and machines cooperate to generate knowledge in a loop centered on the human to provide expert knowledge to the analytical process. Over the years, the acute need for various institutions, ranging from governmental to industry sectors, to shift their decisions to be more data-driven has transformed Visual Analytics into an essential tool, where the user serves as the "oracle" guiding the process. However, with the recent popularization of Generative Artificial Intelligence, particularly the popularization of Large Language Models, the central position of the expert human has started to be challenged, and one question is gaining traction: Can humans be replaced by intelligent (machine) agents in the analytical loop? In this talk, I will explore this new direction to raise awareness about possibilities and opportunities while pointing out intrinsic limitations.

Title
Ethics Readiness Levels: An Ethics-by-Design Approach for Data and AI
Abstract
It is a common practice in the European Union to frame ethical constraints on emerging technologies as “soft law”: codes of conduct, codes of practice, or guidelines. In domains of Data and Artificial Intelligence the “soft law” has given rise to “hard law” or regulation in GDPR and AI Act. However, the deontological approach based on values fails to grasp the complexity of developing technology, essentially trying to codify into high-level principles what are local, contextual, and embedded processes. As an alternative, I present an ethics-by-design methodology that uses a structured dialogue-based approach to 1) introduce ethics during the design of the system, as opposed to audits and standard conformity, which happens at then end, when the design is already finalized, 2) uses dialogue to elicit ethical reflection in a concrete use case setting, rather than working with abstract principles; and 3) produces a measurable track record of ethics maturity of a component over time. The ethics-by-design methodology is based on the idea of “ethics readiness”, structurally similar to the idea of “technological readiness levels.” It introduces ethical issues and concerns to the innovators in their own operating field and to guide their thinking in a systematic way. The dialogue on ethical issues involving different stakeholders should occur regularly and often recursively at different times and run in parallel with, and inform, the process of scientific research and technological design.

Title: Taxonomy-Driven Approaches for Exploring Movement Data
Abstract
The increasing availability of movement data—from ships and wildlife to storms and sports—offers unprecedented opportunities for understanding dynamic behaviors across domains. Yet this abundance also brings significant challenges: high dimensionality, lack of labels, and difficulty extracting interpretable patterns that can inform scientific hypotheses and practical applications. While valuable, traditional exploratory data analysis techniques often fall short in managing such complexity.
In this talk, I will present our efforts to address these challenges in two stages. First, we developed a theoretical framework that organizes movement variables into a structured taxonomy and leverages anomaly detection to reveal meaningful patterns in unlabeled, high-dimensional datasets. This provides a foundation for describing movement behaviors in an interpretable way. Building on this theoretical groundwork, we advanced toward practice by designing a visual analytics tool that operationalizes these ideas. The tool bridges statistical descriptors and interactive visualization, enabling analysts to explore movement data across multiple levels of abstraction.
Together, these contributions show how theory and tool development can be combined to advance our ability to describe and make sense of complex movement data, opening new avenues for exploratory analysis and knowledge discovery in diverse scientific and applied contexts.

Artificial ‘ulama - Analyzing AI-Generated Islamic Theology
Abstract
The presentation provides information on, and preliminary findings from my research project Artificial ‘Ulama,examining how artificial intelligence systems produce Islamic theological content. The study focusses on how modern Large Language Models interpret and respond to prompts based on Islamic texts, concepts, and interpretational frameworks.
The investigation focuses on three domains: Qur'anic interpretation, religious counseling (fatwa), and contentious topics in Islamic faith and practice. Through systematic prompting with Islamic queries, I collect AI-generated theological responses and analyze the results through both distant and close reading techniques.
Our initial results reveal patterns of consistency and variation in AI theological approaches, offering insights into how algorithmic systems process Islamic knowledge. By comparing these outputs with established human interpretations, we identify convergences and divergences from traditional scholarly positions.

Condition Based Monitoring at Scale
Abstract
Condition-based monitoring of assets has long been employed in process industry for early detection of, possibly catastrophic failures, to protect assets and mitigate monetary loss. Traditionally online hard-wired vibration monitoring of a few key assets has been feasible. However, resent advancements in sensor technology, computational power and communication, have made sensors with higher sensitivity and bandwidth more affordable and accessible. With the development of long-range wireless communication large scale deployment of sensors has now become tractable. Södra Cell has made a strategic investment in large scale deployment of vibration monitoring sensors across all its production sites, with to goal of reaching an installed base of ~ 5.000 to 10.000 sensors. Typically, each asset would be assigned a unique set of monitoring characteristics which necessitates a judicious choice of computational methods, monitored frequencies, intensities and alarm thresholds. This highly specialized configuration is performed by a few, hard to come by, experts possessing deep knowledge within the specific field. Due to the noisy and intermittent environment, that makes up a process industry, continuous work on adjusting asset configurations is necessary, where factors such as intermittency and cross contamination between neighboring equipment plays a large role. As the number of deployed sensors continuous to increase, it continuously challenges the organization managing and monitoring the asset fleet. Thus, new and more automated ways to monitor and manage the ever-growing flood of information overwhelming the organization is called for. Together with Viking Analytics, Södra Cell has explored new ways of leveraging AI and ML to support and augment the human expert to support condition-based asset monitoring at scale.

Title
Anomaly Dectection in Unlabeled Signals
Abstract
In this work, we propose a novel approach to anomaly detection utilizing normalizing flows, a type of deep generative model, and an adaptive learning scheme that implicitly labels samples based on their influence on the learning process. The method dynamically disregards samples whose loss significantly deviates from the mean during training, effectively treating them as noise or anomalies. We empirically demonstrate that such discarded samples tend to correspond to rare events and are hence anomalous. Our experimental results on synthetic datasets with varying levels of anomaly severity indicate that this method is robust and performs comparably to or better than a vanilla normalizing flow, even approaching the performance of a model trained solely on noise-free nominal data in many cases. We also evaluate the method on a real-world industrial dataset from bearing ring manufacturing, showing its capability to exclude unwanted noisy signals. Despite limitations in testing across diverse datasets like image data and the need for manual hyperparameter tuning, this approach offers a promising direction for robust anomaly detection in noisy, unlabeled industrial signals.

Deep Reinforcement Learning: From Foundations to Boundaries
Abstract
Deep Reinforcement Learning (DRL) has emerged as one of the most powerful paradigms in artificial intelligence, enabling agents to learn complex behaviors from raw sensory inputs through interaction with their environments. In this talk, we explore the foundational concepts of reinforcement learning and illustrate how deep learning extends its capabilities to high-dimensional problems. We review key DRL algorithms—such as DQN, PPO, and Actor-Critic methods—and examine their applications in robotics, autonomous systems, gaming, and cybersecurity. We also address the critical challenges in training DRL agents, including sample inefficiency and stability issues, and highlight emerging trends like multi-agent systems and offline RL. The presentation aims to provide a conceptual roadmap for the future of DRL in real-world decision-making systems.

Distributional Reinforcement Learning
Abstract
Distributional Reinforcement Learning (DRL) represents a recent and successful paradigm shift in reinforcement learning, especially for algorithms based on deep learning. Instead of estimating only expected returns, DRL agents learn the full distribution of possible outcomes, which admits a richer representation and greater flexibility for algorithm design. This approach has led to improved empirical performance in complex environments and enables new capabilities, such as risk-sensitive behavior.

The past present and future of wearables in health research
Abstract
Sensor-based assessments of physical activity have been available for over three decades. Initially, these technologies were primarily utilized by specialized researchers. However, in the past ten years, the consumer market for wearable devices—such as smartwatches and activity trackers—has expanded rapidly within the fitness industry. Recent innovations have improved the cost, size, and technical capability of wearables but their precision and transparency has not increased at a corresponding pace. Despite these limitations, the multifunctionality of wearables, akin to a "Swiss army knife," has sparked discussions about the potential of wearables as tools for self-monitoring and use in healthcare settings. Especially since they allow for the collection of long measurement periods of high-resolution information regarding both exposure and outcome simultaneously. In this presentation I will introduce the research area and describe some of the challenges that we must overcome so that in the future individuals may be able to improve and maintain their health through device-based services and make informed decisions based on their personal health data.

Validating Wearable Technologies for Blood Pressure Measurement: Challenges and Opportunities
Abstract
Hypertension affects nearly half of individuals over 65, yet current treatments often fail to achieve adequate blood pressure control. Increased levels of physical activity (PA) have been shown to positively influence blood pressure and are recommended for hypertension treatment. Evidence-based tools for modifying PA are lacking, and while wearables offer a promising solution for self-monitoring, only 11% have been validated — often with poor results. There is a need to validate and develop self-learning algorithms that can be implemented in wearables in order to suggest an appropriate level of PA based on blood pressure response to optimize blood pressure in patients with hypertension. The talk will share challenges and insights using wearable sensors to estimate systolic and diastolic blood pressure, focusing on data analysis from Bangle.js and EmotiBit devices.

Title
Ecological monitoring of physical activity from everyday data collected with digital health technology. Insights and significance for healthcare.
Abstract
With the advent of wearable devices and the widespread use of smartphones, people are increasingly collecting physical activity data from their everyday lives, collecting plenty of information, from steps, heart rate and heart rate variability, to measures of stress and energy levels. Movement and an active lifestyle can be considered as a prescription or intervention tool by doctors towards their patients. This happens in various conditions, such as cardiovascular or respiratory conditions, but also mental disorders and chronic diseases.
Despite the rich state-of-the-art of wearable devices and technology, there is a general lack of transparency with how metrics are computed, their accuracy and clinical relevance for healthcare.
This work investigates how physical activity measured during everyday life relates to standard physical capacity assessments such as the 6-Minute Walk Test and the Timed Up and Go Test. These tests are performed in today's traditional practices to investigate changes in patients' physical capacity, however, they have some shortcomings. They are usually performed with large time gaps from one hospital visit to the other, they struggle to be representative of natural symptom fluctuations and they have significant costs in terms of time and physical space for both patients and healthcare providers. Associating and inferring the test outcomes from everyday data has the potential to 1) provide more frequent assessment, 2) likely introduce a better representation of natural behaviour and activity levels, and 3) avoid high costs and travel times for clinicians and patients. In this context, transparent, reliable and actionable insights must be validated across populations, contexts and technology.

Making Sense of Wearable Data: Physiology Meets Data Science
Abstract
As data from wearables—covering activity, sleep, and other daily metrics—continues to grow, new opportunities emerge to optimize health and performance at the individual level. At Svexa, we specialize in the development of data-driven “digital twins”—individualized models of physiology, recovery, and performance—used to simulate and translate complex data into actionable insights.This talk will explore how we leverage large, heterogeneous data sources and combine classical physiological models with machine learning pipelines to detect conditions such as overtraining and enhance training effectiveness.Many key physiological traits require laboratory-grade testing to assess accurately. At Svexa, we aim to infer such traits through data analysis—identifying patterns that allow us to estimate individual properties without the need for direct measurement. These patterns form the foundation of each person’s digital twin.
A major challenge in this space is data quality. Wearables can produce noisy or inconsistent measurements, and values can also vary significantly between sources. It will be discussed how these issues are tackled using a combination of data-driven individual modeling and domain-specific physiological expertise.This presentation aims to show how data science, when grounded in physiological understanding, can bridge the gap between data-driven insights and real-world variability in human data.

This include direct negative impacts from the energy used and the production of the required hardware, and also indirect impacts as the technology is used, which can be positive if we are tackling a problem like saving energy, or negative if we are using technology to augment a problem. The presentation will provide some reflections about opportunity areas, risks and challenges and some points to think about in our role as technologists.

Title
Accelerating Circular Scale-Up in a Volatile World
Abstract
Transforming sustainable lab innovations into full-scale industrial systems is rarely straightforward—especially in a world defined by volatile markets, complex material flows, and unpredictable disruptions. This talk will introduce a decision-first approach to scale-up, where digital twins and AI-powered scenario modeling help organizations accelerate innovation while managing uncertainty.
Drawing on experience from the environmental technology and waste valorization sector and recent projects like the Formas-funded PLENTY Center, Graham Aid shows how digital tools can tame the complexity of circular scaling—from variable feedstocks to dynamic downstream markets. This method prioritizes agility over infrastructure, using simulation and learning loops to make better choices early—before locking in costly commitments.
With roots in earlier architecture work from ISDATA.org, this presentation makes the case for data-first strategies in green innovation, highlighting how researchers and sustainability leaders alike can build resilience and fast-track promising ideas into profitable, scalable systems.

Title
Architecting Carbon-aware Software-as-a-Service Applications
Abstract
Software-as-a-Service solutions are increasingly being adopted when developing software applications, as they are scalable, cost-effective, and facilitate rapid deployment while providing high availability and flexibility. However, the impact of Software-as-a-Service in terms of carbon emissions is not yet adequately addressed as a design concern, and most of the existing efforts revolve around measuring and containing the carbon impact after the deployment. This talk introduces a model-driven reasoning framework that integrates UML-based software architecture modeling with carbon-aware concerns. Architectural elements are supplemented with sustainability and performance properties of interest, and a model-driven transformation generates a simulation model to evaluate multiple architectural designs according to their Software Carbon Intensity and performance metrics. The results guide decision-making by assessing and comparing the trade-offs between performance and carbon intensity for the analyzed designs. In this way, the reasoning framework provides an automated, tool-supported approach to designing environmentally responsible Software-as-a-Service applications.

Title
Ethics Readiness Levels: An Ethics-by-Design Approach for Data and AI
Abstract
It is a common practice in the European Union to frame ethical constraints on emerging technologies as “soft law”: codes of conduct, codes of practice, or guidelines. In domains of Data and Artificial Intelligence the “soft law” has given rise to “hard law” or regulation in GDPR and AI Act. However, the deontological approach based on values fails to grasp the complexity of developing technology, essentially trying to codify into high-level principles what are local, contextual, and embedded processes. As an alternative, I present an ethics-by-design methodology that uses a structured dialogue-based approach to 1) introduce ethics during the design of the system, as opposed to audits and standard conformity, which happens at then end, when the design is already finalized, 2) uses dialogue to elicit ethical reflection in a concrete use case setting, rather than working with abstract principles; and 3) produces a measurable track record of ethics maturity of a component over time. The ethics-by-design methodology is based on the idea of “ethics readiness”, structurally similar to the idea of “technological readiness levels.” It introduces ethical issues and concerns to the innovators in their own operating field and to guide their thinking in a systematic way. The dialogue on ethical issues involving different stakeholders should occur regularly and often recursively at different times and run in parallel with, and inform, the process of scientific research and technological design.
