The second session of contributed talks is kicking off now. First talk coming up: SemCLIP: A Semantic Memory Aligned Vision Language Model by Tanveer Syeda-Mahmood 🚀

We now continue after the break with Randall Balestriero from Brown University, presenting “LeJEPA: Provable and Scalable Self-Supervised Learning Without the Heuristics ” 👏

Up next, our Mentorship Panel featuring @abeirami.bsky.social, @sarahooker.bsky.social, and @meenakshikhosla.bsky.social moderated by @icannistraci.bsky.social. Excited to have such inspiring leaders sharing their perspectives on the current state of the ML peer-review system! 🔍✨

Fifth and final talk of Session 1: "On Defining Neural Averaging" by Su Hyeong Lee 🧠⚡️

Fourth talk: "Superposition disentanglement of neural representations reveals hidden alignment" by André Longon 💡🌟

Third talk: "Universally Converging Representations of Matter Across Scientific Foundation Models" by Sathya Edamadaka and Soojung Yang 📊⚡️

Second talk: "Neuron-Level Linguistic Selectivity in LLMs via Minimal Pairs: A Neuroscience-Inspired Framework" by Linyang He 🧠✨

Session 1 of the Contributed Talks start now! 🚀 First talk: Neural Embedding Alignment Reveals Nonlinear Latent Transformations across Brain Regions by Stephen Keeley

Did you know that you could create hybrids across different neural net architectures—*without* updating the weights?? Come check out my poster at the UniReps @unireps.bsky.social workshop at 3:45pm today at #NeurIPS! (Or you can already browse the posters on the wall in 20D throughout the day.) 😃

I thought this was a fascinating way to motivate model merging: to be able to *interpolate* between model classes, rather than be forced into discrete choices. (models trained on different datasets, models of different sizes, etc.) "Interpolation and alignment are two sides of the same coin."

It’s our pleasure to welcome @dmelis.bsky.social from Harvard SEAS to UniReps 2025, presenting “From Discrete to Continuous: Interpolating Models, Datasets, and Representations!” 🔁📊 Join us in Ballroom 20D for more exciting discussions on representational alignment!

We now continue with Prof. Nikolaus Kriegeskorte from Columbia University, presenting "Meaningful and Powerful Model Comparisons"!

We are thrilled to announce our first invited talk this morning, featuring Prof. Rose Yu (@yuqirose.bsky.social) from UC San Diego, presenting “Fantastic Symmetries and Where to Find Them” at the UniReps workshop! 🎤✨

Welcome to UniReps 2025 🔵🔴 Opening remarks by @marcofm.bsky.social We have an exciting day ahead of us - join us at *Ballroom 20d* for amazing talks, posters and discussions on representational alignment!

After a full weekend of NeurIPS workshops, join us Sunday at 5:30pm for the Workshop Wind-Down Happy Hour! Sponsored by New Theory, in partnership with @neurreps.bsky.social, @unireps.bsky.social ! partiful.com/e/lWLf12qszY... Come wrap up the week with us! 🍹✨

Join us this Saturday at @neuripsconf.bsky.social 2025 for the @unireps.bsky.social Workshop.

🔵🔴 Join us for the UniReps Workshop: Unifying Representations in Neural Models at @neuripsconf.bsky.social 2025! 📍 Ballroom 20D, San Diego Convention Center Dec 6 Don’t forget to fill out the participation form. Joining in person or remotely? We welcome your questions for the panel. 🔗 unireps.org

I’ll have a poster at @unireps.bsky.social 🔵🔴 It’s a terrific workshop at the intersection of neuroscience and DL: across both biological and artificial NNs, how can we measure / compare / align / merge neural representations? Should be fascinating! Check it out if you're around! unireps.org/2025
