Northern Lights Deep Learning Conference 🌌

We organize the annual Northern Lights Deep Learning Conference (NLDL), an international venue that brings together researchers to exchange ideas and present cutting-edge work in deep learning and machine learning. The conference is held each January in Tromsø, Norway, and includes a winter school alongside the main program.

EditionDates
NLDL 2027January 12–14, 2027

Tutorials and educational material from past editions can be found in our repositories, such as GraphMLTutorialNLDL22.

Computing infrastructure 🖥️

Group members have access to Springfield, our internal GPU-powered Kubernetes compute cluster. The cluster nodes are named after characters from The Simpsons, with the cluster itself named after the town of Springfield. Infrastructure specifications and deployment manifests are maintained in the springfield repository.
