New preprint w/ Malin Styrnal & @martinhebart.bsky.social

Have you ever computed noise ceilings to understand how well a model performs? We wrote a clarifying note on a subtle and common misapplication that can make models appear quite a lot better than they are.

We recently stumbled upon a surprisingly common misunderstanding in computing noise ceilings that can be quite consequential. So if you care about noise ceilings, please check out Sander’s thread and our preprint! 👇

YouTube video by Michigan Medicine Sensory Horizons and Visual Consciousness in Non-Human Animal

Recording of a talk on "Sensory Horizons and Visual Consciousness in Non-human Animals" (www.youtube.com/watch?v=z_Pz...) at the University of Michigan. Based on the recent BBS paper on sensory horizons and consciousness w/ @smfleming.bsky.social.

Sensory reformatting for a working visual memory A core function of visual working memory (WM) is to sustain mental representations of recent visual inputs, thereby bridging moments of experience. This is thought to occur in part by recruiting early...

GUARDIAN: “Per head, 🇺🇸 output is six times China’s, and yet, inexplicably, there seem to be more abjectly poor Americans than Chinese. 🇺🇸 inequality is breathtaking… keeps getting worse…”

Wanting to address this isn’t radical.

NOT wanting to is.

Great study by @lunahuestegge.bsky.social and @nadinedijkstra.bsky.social using TMS to investigate the causal role of early visual cortex in imagery-induced false percepts.

Today we’ll get latest net immigration figures - They’ll show immigration for work is plummeting.

Why is this not part of the discussion on Rachel Reeves balancing her books & stalled growth?

For every 100,000 drop in net immigration, the OBR adds £7bn to the deficit. #r4today

Terrific work led by @emmaroscow.bsky.social showing that hippocampal replay reflects events with large prediction errors, all the better to bootstrap learning as we slumber

Congratulations to Matt Jones & Nathan Lepora for seeing this through to the end!

The war will end when Russia stops fighting. Therefore, pressure has to be put on Russia, so that they stop believing that they will win. Why is that so hard to understand?

NOS plaatst vanaf vandaag geen nieuwsberichten meer op X - Over NOS De NOS en Nieuwsuur (NOS/NTR) zijn gestopt met posten op X. Het platform past niet meer bij onze visie op...

A small but significant step: Dutch national broadcaster NOS is leaving X.

“The volume of hateful comments and disinformation on X is enormous and flows freely. This also applies under our own posts, meaning we unintentionally contribute to their spread”

You’ve been kidnapped. The characters from the last TV show you watched are trying to rescue you. Who’s coming to save you?

Every machine in a Hospital that diagnoses your body without cutting you open is based on a principle of Physics, discovered by a Physicist who had no interest in Medicine.

If you think the world doesn’t need Basic Science, or that somehow Science has failed you, think again.
