Professor Anis Yazidi from DSB has co-authored three NeurIPS 2026 papers on learning, foraging, and evolution.
A new study for a long-horizon agentic framework that generates documentation within a single, integrated context spanning the entire repository has been accepted at NeurIPS 2026. This work is authored by Suyoung Bae, a visiting researcher under AURoRA, the Norway-Korea joint research project on low-resource large vision-language models.
This paper by Sigurd Holmsen et al. has been accepted at NeurIPS 2026. We introduce a non-parametric mutual information estimator that uses vine copulas to offer fast, interpretable, and accurate estimates.
Deep-learning models work well on medical images, but whole-slide images (WSIs) used in histopathology are so large that researchers usually have to freeze much of the model (the whole encoder) during training. This work proposes a novel method to train the full model end-to-end under realistic GPU memory constraints and investigates when this is beneficial.
Hi everyone, my name is Meike Nienaber and I am joining the Digital Signal Processing and Image Analysis (DSB) and Visual Intelligence groups as a PhD fellow!
A hierarchical contrastive learning framework that effectively captures both local and global temporal patterns in time-series analysis by using a progressive memory attention architecture.

We had the pleasure of hosting Marcella Bonazzoli from Inria and Morgane Mathevet from EDF, both members of the IDEFIX team, at the DSB group at the University of Oslo.
Jiin Han, a visiting researcher from Sungkyunkwan University under AURoRA, the Norway-Korea joint research project on low-resource large vision-language models, has returned to South Korea after a three-month stay with us.
A new study addressing code localization in automated software engineering has been accepted at EMNLP 2026 main track. This work is co-authored by Suyoung Bae, a visiting researcher under AURoRA, the Norway-Korea joint research project on low-resource large vision-language models.
We are pleased to welcome Suyoung Bae and Doyoung Kim from Sungkyunkwan University (SKKU), and Erling Arvola Devold from the Institute for Cancer Genetics and Informatics at Oslo University Hospital.
A new study addressing speed-of-sound aberrations in obstetric imaging has been published in IEEE Transactions on Medical Imaging (TMI). The work, co-authored by Ole Marius Hoel Rindal, introduces a coherence-based method to estimate and correct for tissue-induced aberrations in real-time, sharpening B-mode images and improving fetal measurement precision.
We have a new project received seed funding from MishMash Centre for AI and Creativity and we are looking for one motivated MS student:
Title: Agency and Control in Musical Ensemble
The central inquiry of the project concerns the location of creative agency when no individual agent, whether human or artificial, ever perceives the complete work.
The project investigates where creative agency is located when neither human nor machine ever perceives the complete musical composition. A work is constructed from an ensemble of agents that never interact directly — one shapes rhythm, another timbre, a third the overall structure, and a fourth, a digital signal-processing layer, determines acoustic feasibility. An additional, often unacknowledged contributor is introduced: using RITMO’s Oslo Standstill recordings of individuals attempting, yet failing, to stand still during musical playback, the involuntary micro-movements of audience members’ bodies generate the rhythmic foundation, allowing the audience to contribute to the composition prior to experiencing it. The project quantitatively assesses the proportion of the final work attributable to these absent bodies, to each machine agent, and to their collective interaction.
We will collaborate closely with RITMO and MishMash researchers.
Ideal candidate: someone with expertise in deep learning + interest in music
Salary is 40k NOK.

In this article, we propose applying a KDE-based method to estimate speckle PDFs in medical ultrasound imaging. The method is practically tuning-free and leverages the Box-Cox transformation to achieve best-in-class performance across a wide range of test cases.
The Vision Transformer (ViT) signifies a new direction in modelling spatial data, representing a shift in focus from local spatial interactions to global contextual relationships. Traditionally, ViTs partition images into square patches to extract tokenized features. But is this necessarily an optimal way of partitioning images for transformers?
