🥳 I am incredibly humbled and grateful to share that our work, "Aligning machine and human visual representations across abstraction levels," has been published today in @nature.com ⬇️

Andrew Lampinen@lampinen.bsky.social

What aspects of human knowledge do vision models like CLIP fail to capture, and how can we improve them? We suggest models miss key global organization; aligning them makes them more robust. Check out LukasMuttenthaler's work, finally out (in Nature!?) www.nature.com/articles/s41... + our blog! 1/3

🔮At #ICML2026 we presented Attentive Multi-Layer Fusion for Vision Transformers, an efficient method for decoding information from multiple layers of ViTs for downstream task predictions. It’s almost as performant as full fine-tuning but only an inch more expensive than linear probing!

🚨Go check out our most recent preprint on multilayer attention probing for Vision Transformers! It’s almost as performant as full fine-tuning while being similarly compute efficient as standard linear probing! Plus you get interpretable attention maps!

Why you should probe more than just the final layer of your Vision Transformer to maximize performance. 🧵👇

Even though I am not part of the Re-Align organizer team anymore, I am still cheering for this workshop! I still (and will always) believe that Re-Align is a great place for connecting the fields of AI / ML, Neuroscience, and Cognitive Science :) Can highly recommend submitting! 🧠🤖

New post! Last week I shared why I thought cognitive (neuro)science hasn’t contributed as much as one might hope to the design of AI systems; this week I'm sharing my thoughts on how methods and principles from these fields *have* been useful in my work. infinitefaculty.substack.com/p/how-cognit...

What is representational alignment? How can we use it to study or improve intelligent systems? What challenges might we face? In a new paper (arxiv.org/abs/2310.13018 ), we describe a framework that attempts to unify ideas from cognitive science, neuroscience and AI to address these questions. 1/2

If two models are more similar to each other than a third on ImageNet, will this hold for medical/satellite images? Our #icml2025 paper analyses how vision model similarities generalize across datasets, the factors that influence them, and their link to downstream task behavior. 🧵1/7

Harvard has set an example for other higher-ed institutions - rejecting an unlawful and ham-handed attempt to stifle academic freedom, while taking steps to make sure students can benefit from an environment of intellectual inquiry, rigorous debate and mutual respect. Let’s hope others follow suit.

I encourage all of my friends and fellow scientists in the US to go outside and march against Trump’s and Elon’s oligarchy. There’s nothing at this point that is more important than fighting for democracy! Democracy is in real danger and we here in Europa are concerned about the recent developments.

This is an incredibly moving and powerful read. We shall see it as a reminder to check in with the people around us and help build a collaborative culture of kind relationships that encourages openness about our mental states rather than a competitive culture full of selfishness and greed.

What counts as in-context learning (ICL)? Typically, you might think of it as learning a task from a few examples. However, we’ve just written a perspective (arxiv.org/abs/2412.03782) suggesting interpreting a much broader spectrum of behaviors as ICL! Quick summary thread: 1/7

Unfortunately, I am not attending NeurIPS this year but don’t miss our work on perceptual alignment presented by @shobsund.bsky.social and Stephanie Fu in the Thursday morning session! 🧠🤖

Phillip Isola@phillipisola.bsky.social

First up, "When Does Perceptual Alignment Benefit Vision Representations?" (arxiv.org/abs/2410.10817) This paper is about distance between embeddings. It says: measure how humans perceive distance, then adjust a neural net to match. This improves transfer to lots of tasks (but not all tasks).

Reposting this because I just started using Bluesky 🦋 Excited to share what we’ve been working on during my time at DeepMind! We came up with an approach that can distill the hierarchical structure of human conceptual knowledge into vision foundation models via a surrogate teacher model. More below👇🏼

We employed a triplet odd-one-out task (🥸,🤓,😎) and distributed it online to thousands of participants. We then trained sparse (#VICE, @lukasmut.bsky.social) and deep encoding models (#VGG-Face) to investigate the latent representations underlying human face similarity judgments. #alignment (2/n)
