There’s lots of symmetry in neural networks!
🔍 We survey where they appear, how they shape loss landscapes and learning dynamics, and applications in optimization, weight space learning, and much more.

⏳ Less than one week until our CFP closes!
Working on model populations, weights, gradients, representations, or training trajectories? We'd love to see your work at our #NeurIPS2026 workshop on neural network artifacts.
🗓 Deadline: Sept 1 AoE

📣 CFP: Neural Network Artifacts Are Data Too!
We welcome extended abstracts & full papers on model populations, weights, gradients, representations & training dynamics for our #NeurIPS2026 workshop.
Join us in Paris!

How do LLMs organize emotion concepts?
Excited to share our #ICML2026 paper: we uncover emergent “emotion trees” in LLMs, inspired by emotion wheels from psychology.

Excited to contribute a small piece to the growing work on affective cognition and internal representations in LLMs!
We also hope our label-free tree-construction algorithm will find more applications beyond emotion.

I defended my PhD thesis "Symmetry in Neural Networks"!
Grateful to my advisor @yuqirose and committee Mikhail Belkin, Sicun Gao, and Barna Saha, as well as mentors, colleagues, and friends.
Next stop: postdoc with @mweber_PU at Harvard's Geometric Machine Learning Group!

🎉 Our paper on interpretable model mergeability prediction has been accepted to ICML 2026!
Excited to share this joint work on understanding when model merging succeeds, with amazing co-authors @bozhao, @yuqirose, and @EmanueleRodola 🙏
Happy to chat in Seoul! 🇰🇷
