Interesting convergence: The trick that made predictive self-supervised vision models work seems to be what the brain was doing all along w/ @predictivebrain.bsky.social: visual cortex is most sensitive to high-level prediction errors -- even in V1 Now published: journals.plos.org/ploscompbiol... - Reposted by Floris de Lange"Forward and backward prediction in learning and perception" @predictivebrain.bsky.social @clarepress.bsky.social nice to see our work situated within a broader research program on differences between learning & perceptual predictions www.sciencedirect.com/science/arti...
- Reposted by Floris de LangeReally thrilled that this paper led by @neurozz.bsky.social is now published in its final version in @elife.bsky.social!! This is a memory-focused (as opposed to RL-focused) account of the detailed characteristics of forward and backward awake and sleep replay! elifesciences.org/articles/99931

The physicist who led that transformation says the same playbook could work anywhere—if governments have the courage to change the rules.”
- Reposted by Floris de LangeWith some trepidation, I'm putting this out into the world: gershmanlab.com/textbook.html It's a textbook called Computational Foundations of Cognitive Neuroscience, which I wrote for my class. My hope is that this will be a living document, continuously improved as I get feedback.

- Reposted by Floris de LangeThis paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!
- Would love to hear expert views on this paper. It appears to show that the operationalization of brain activity the field has relied on for 3 decades—the BOLD response—is not actually a sensible measure of brain activity. www.nature.com/articles/s41...

We've got a lot of problems in America today, and invading / occupying / running Venezuela does not solve any of them."

- Reposted by Floris de LangeThere's been a cluster of recent work on these sort of flow based or trajectory based world models, including nova flow and amplify (amplify a past episode of ours). These are super exciting because they reduce requirements for really accurate action labels imo

- Reposted by Floris de LangeUsing brain lesions and DNN models, this article suggests that human visual perception is modulated by language.
- Reposted by Floris de LangeDimensionality reduction may be the wrong approach to understanding neural representations. Our new paper shows that across human visual cortex, dimensionality is unbounded and scales with dataset size—we show this across nearly four orders of magnitude. journals.plos.org/ploscompbiol...

- Reposted by Floris de LangeNice piece about extreme multiverse analysis! The exemplar study performed 3.6 billion regression models. The author argues against this approach and suggests that multiverse analysis should only include valid models selected based on theories. Statistical inference requires thinking before acting🤓
