Thrilled, grateful, and humbled to have won 3 outstanding paper awards at #EMNLP2024!!! Not even in my wildest dreams. Immense thanks to my amazing students and collaborators!
All three works are on evaluating LLM’ abilities in creative narrative generation. 🧵👇

Congrats @ysu_nlp for this exciting launch! Cannot wait to see what will come out from @NeoCognition!

[Yu Su @ysu_nlp]

Introducing @NeoCognition, the agent lab for specialized intelligence.

Everyone needs experts, but human expertise does not scale.

Backed by $40M seed funding, we build self-learning agents that specialize across domains to make expertise abundant.

[Kai-Wei Chang @kaiwei_chang]

Excited to work with a world-class team (@sahaiamit, Raghu Meka,@VioletNPeng,@terrence_tao,@WeiWang1973) on AI for math discovery and thank @LaudeInstitute for the support. I'm hiring a postdoc in this direction. Please contact me by May 1, 2026, if you’re interested.

[Lucas Bandarkar @LucasBandarkar]

I'll be attending ICLR in a few weeks to present Multilingual Routing in Mixture-of-Experts
Lmk if you're attending and want to talk MoEs, interpretability, multilinguality, etc

[Prof. Anima Anandkumar @AnimaAnandkumar]

We’re excited to release TorchLean which is the first fully verified neural network framework in Lean. The Lean community has largely focused on pure mathematics. TorchLean expands this frontier toward verified neural network software and scientific computing. With the recent release of CSlib, we see this as another step toward a fully verified ML stack.

We support features:
1. Executable IEEE-754 floating-point semantics (and extensible alternative FP models) verified tensor abstractions with precise shape/indexing semantics
2. Formally verified autograd system for differentiation of NN programs Proof-checked certification / verification algorithms like CROWN (robustness, bounds, etc.)
3. PyTorch-inspired modeling API with eager-style development + export/lowering to a shared IR for execution and verification

Paper: [2602.22631] TorchLean: Formalizing Neural Networks in Lean
Work done @Robertljg, Jennifer Cruden, Xiangru Zhong, @huan_zhang12 and @AnimaAnandkumar.

Grateful for the generous support and looking forward to strengthening our collaborations with Salesforce researchers! @jasonwu0731 @steeve__huang

[Salesforce AI Research @SFResearch]

(2/4) Nanyun (Violet) Peng @VioletNPeng @UCLA is developing MAP-SE, a Multi-Agent Persuasion Simulation Engine that studies how influence emerges across adaptive agents with long-term memory—moving beyond simple one-on-one interactions. #AIResearch #AgenticAI

[Violet Peng @VioletNPeng]

@Diyi_Yang @humansand Congrats! Enjoy the fun!

[Alex Spangher @ Neurips2025 @AlexanderSpangh]

Neurips 2025 was such a blast! We snuck a grand piano into the CreativeAI Track to demo Aria, our pretrained chat-style music model:

📸 Fantastic experience with @uclanlp at @NeurIPSConf 2025. An inspiring week of ideas and new connections.

[Violet Peng @VioletNPeng]

@sivareddyg Congrats, Siva. Well deserved!

[Jia-Chen Gu @Jiachen_Gu]

Extremely honored to be nominated for the @UCLA Chancellor’s Award for Postdoctoral Research!
Deeply grateful to @VioletNPeng and @kaiwei_chang for the nomination, and to my friends at @UCLANLP for their support!
I’m on the academic market now. Reach out if I might be a good fit!

[Violet Peng @VioletNPeng]

If you’re interested in AI for humanity — computational journalism, creativity, narratives, etc. You should apply to work with Alex!

[Alex Spangher @ Neurips2025 @AlexanderSpangh]

✨ Very overdue update:

I'll be starting as an Assistant Professor in CS at University of Minnesota, Twin Cities, Fall 2026. I will be recruiting PhD students!!

Please help me spread the word! [Thread] 1/n

[Haoyi Qiu @HaoyiQiu]

🎉 Excited to share that our 𝗠𝘂𝗹𝘁𝗶𝗺𝗼𝗱𝗮𝗹 𝗖𝘂𝗹𝘁𝘂𝗿𝗮𝗹 𝗦𝗮𝗳𝗲𝘁𝘆 paper is accepted at TMLR 2025!

Grateful to all collaborators — this continues our series of projects on 𝗰𝘂𝗹𝘁𝘂𝗿𝗮𝗹 𝘀𝗲𝗻𝘀𝗶𝘁𝗶𝘃𝗶𝘁𝘆 𝗮𝗻𝗱 𝘀𝗮𝗳𝗲𝘁𝘆:

1️⃣ SafeWorld: Geo-Diverse Safety Alignment (NeurIPS 2024)
