Was a very fun (and quick) investigation into biases of multimodal benchmarks, this time on tasks designed for "Spatial Supersensing" introduced by Cambrian-S with some great folks!

I am hiring a PhD & postdoc to work together with me at KTH on probabilistic machine learning. Both positions are fully funded and part of WASP.
I will be attending @euripsconf.bsky.social, if you are around and want to talk about the positions or what we do at KTH, then ping me and we can meet.

Ok, I can proudly say that I commuted in some peculiar ways over the years, including swimming, kayaking, and taking overnight ferries. It’s so much more fun to commute in creative ways than taking the car or public transport every day.

Newly released Stockholm Declaration recommends the following reforms to publishing:
1. Academia resumes control of publishing
2. Incentive systems to merit quality, not quantity
3. Independent fraud detection and prevention
4. Legislation and policies to protect science quality and integrity
