Efficient and precise annotation of local structures in data
Event date: 2025-05-22.
Webinar with John Martinsson, RISE and Lund University. Machine learning models now help scientists analyze vast datasets across every branch of science. These models typically improve with more data and larger architectures, mainly through supervised learning. Both training and evaluation therefore rely on labeled datasets. A main challenge is scaling the data labeling effort to the volumes required, because it is costly and label quality can vary. Methods that deliver inexpensive yet accurate labels are therefore essential. This talk examines how to lower annotation cost and increase label quality when labeling local structures in data—for example, a local structure can be a sound event in an audio recording. By detecting the boundaries of such structures automatically, we let annotators focus on supplying concise textual descriptions for the content within those boundaries. In this setting we analyze a widely used labeling method for audio where fixed and equal length audio segments are labeled with presence or absence of an event class. We benchmark it against an oracle method that defines an upper bound, and propose adaptive labeling techniques that achieve higher‑quality labels for the studied datasets at a lower cost.

DIGeMERGE 2025 Conference
Event date: 2025-08-14.
DiGeMERGE 2025 is an international conference organized by researchers from the Digital Emergency Communication (DIGeMERGE) project. Funded under the CHANSE programme by the EU Commission (Horizon 2020) and Nordic research councils, DIGeMERGE explores the role of digital tools and platforms in public emergency communication across the Nordic countries. The conference provides a platform for researchers and students to present their work on the digital transformation of public emergency communication. Whether focusing on emergency management theories, risk analysis methods, or empirical case studies, participants will have the opportunity to share insights and engage with scholars from diverse disciplines, including the natural and social sciences.

## The digital revolution of Earth system modelling
*This event took place 2025-05-15.* Webinar with Peter Dueben, European Centre for Medium-Range Weather Forecasts. This talk will outline three revolutions that happened in Earth system modelling in the past decades. The quiet revolution has leveraged better observations and more compute power to allow for constant improvements of prediction quality of the last decades, the digital revolution has enabled us to perform km-scale simulations on modern supercomputers that further increase the quality of our models, and the machine learning revolution has now shown that machine-learned weather models are competitive with physics based weather models for many forecast scores while being easier, smaller and cheaper. This talk will summarize the past developments, explain current challenges and opportunities, and outline how the future of Earth system modelling will look like. In particular, regarding machine-learned foundation models in a physical domain such as Earth system modelling.<br />
