Research group Data Science Research Group

The Data Science Research Group focuses on core data science research, as well as on applications where data science can provide insights for decision making. We formulate novel data science problems and develop algorithmic methods and methodological workflows.

The Data Science Research Group is particularly focusing on exploiting huge amounts of data to enhance data-driven decision-making in areas such as healthcare and integrated vehicle health management. We put special emphasis on sequential and temporal data, as well as on text.

In addition, we are interested in building methods and workflows for explainable machine learning. We aim to describe the opaque machine learning models to humans, and to provide explanations and motivations for each decision of the models. Our main goal is to provide scalable and distributed solutions for maintaining good trade-offs between predictive performance and explainability.

Our methods and solutions are motivated by real-world applications and use cases. The group has particular expertise in mining and model understanding from healthcare and medical data sources. We have also established a strong expertise in predictive maintenance and integrated vehicle management. Finally, we are interested in financial data, environmental data, and data emerging from immersive technologies, such as virtual reality (VR).

Beyond the AI hype: it’s time to add explainability

In order to advance intelligent data analysis, there is a need for novel and potentially game-changing ideas. This assumption is the foundation for the IDA symposium which in 2024 was organised at Stockholm University. Explainable AI was one of the important themes.

Are doctors ready for AI assistants?

AI in healthcare is a promising – and challenging – field. Analysing massive amounts of multimodal patient data could result in better treatments. But first, medical doctors need to trust the models.

“The real game changer is when regular glasses become smart”

Sweating, facial expressions and increased heart rate. Our bodies send signals about our emotions – signals that can be picked up by sensors. The input can then be used to design our next workout, meal or learning experience. Luis Quintero’s research provides a sneak peek into the future.

AI has a bright future in medicine

AI technology is breaking new ground in all areas, not least in medicine. What can we expect in a near and distant future? PhD students and supervisors from five countries gathered at Stockholm University to discuss their projects and learn from each other.
