Xinyi Chen

@hugo_larochelle Thank you so much for being an incredible mentor, and I’m excited for your next venture! Looking forward to hearing more about it!

Today is my last day at Google. I started over 8 years ago, with a mandate to build a team doing bleeding edge AI research from Montreal, in what would be the first big tech AI research lab in the city. These years led to countless amazing scientific contributions from my team, to several initiatives nurturing the Montreal AI ecosystem, and to many new invaluable friendships across the globe at Google. It is with a heavy heart that I say goodbye, but I know I’m leaving behind an exceptionally strong Google DeepMind group in Montreal for which its best accomplishments are still ahead. There are too many people to thank, but I can’t pass on thanking Samy Bengio and @JeffDean who first believed in me and the opportunity of building a research lab in Montreal. I’m still working on determining the details of my next chapter, but certainly it will be grounded in my continuing motivation to leverage and make the most out of our enormous and talented local AI ecosystem.

Looking forward to speaking at @PrincetonSML and next week about neural architectures inspired by dynamical systems: csml.princeton.edu/events/beyond-…

Thank you @max_simchowitz for the shoutout! Making ML more efficient by reasoning about dynamical systems is a really exciting direction, and I look forward to advancing more in this space!

Together with @HazanPrinceton, Cong, @Zanette_ai, and Nati, we are organizing a long program on reinforcement learning and control at @IMSI_Institute! Join us for workshops on frontiers of online/offline RL, control, multi-agent RL, and opportunities to present your research. Application to be a research member is now open with a priority deadline of 1/10: imsi.institute/activities/the…

🚨 @SCSatCMU PhD applications close tomorrow, December 11, at 3:00pm ET! I’m actively recruiting masters and PhD students interested in the theory and practice of decision making with generative models, especially for robotics, RL and world models! CMU is one of the most exciting and forward-thinking institutions in AI. So if you’re itching to know what will happen after this “scale is all you need” phase of ML and Robotics research, join us for a PhD and help build what comes next! 🧵(1/n)

Very excited about our work on spectral transformers!

Want to learn about the math behind robot learning? I'll be presenting an invited talk on "Provable Guarantees for Generative Behavior Cloning" at 11:55am CEST at the 2024 ICML Workshop on Reinforcement Learning at Control (link in 🧵) icml.cc/virtual/2024/w…

I'll be at @icmlconf next week! Giving a plenary talk at the HiLD workshop and an oral on our recent paper (arxiv.org/abs/2405.19534) at the MHFAIA workshop! Pls reach out to chat if you're also interested in any of these topics! 😊

New work w/@sadhikamalladi, @lilyhzhang, @xinyichen2, @QiuyiRichardZ, Rajesh Ranganath, @kchonyc: Contrary to conventional wisdom, RLHF/DPO does *not* produce policies that mostly assign higher likelihood to preferred responses than to less preferred ones.

Open source code for spectral SSM is now available! github.com/google-deepmin… Thanks to our Google DeepMind Princeton team: @danielsuo @naman33k @XinyiChen2

most exciting paper *ever* from our @GoogleAI lab at @Princeton: @naman33k @danielsuo @XinyiChen2 arxiv.org/abs/2312.06837 *** Convolutional filters predetermined by the theory, no learning needed! ***

Excited w. our first research in AI safety & alignment: A game theoretic approach for AI safety via debate: arxiv.org/abs/2312.04792 This is a collaboration with my student @XinyiChen2 , our alumna @_angie_chen from NYU, and Dean Foster:

w. @FeinbergVlad, @jsun105, @_arohan_, @HazanPrinceton: Sketchy (Wed 10:45AM, #1115), check out the linked blog post twitter.com/FeinbergVlad/s…

w. @HazanPrinceton: Online control for meta-optimization (Wed 5PM, #2023) twitter.com/XinyiChen2/sta… We’re looking for student researchers to explore more application of this method! Please reach out if you're interested.

At NeurIPS 2023 until next Sunday! Excited to reconnect with friends, meet new ones, and chat about optimization/online control. I’ll be co-presenting Meta-optimization and Sketchy, details below:

See y'all at NeurIPS next week. Presenting Sketchy w @XinyiChen2 Jennifer Sun @_arohan_ @HazanPrinceton. High level blog post: vladfeinberg.com/2023/10/18/ske… Also, looking for student researchers for OCO🤝Control theory+applied internship! HMU @ NOLA

I will be at NeurIPS - 12th, 13th and will be hanging out at the posters, Sketchy: @FeinbergVlad @XinyiChen2 Jennifer Sun @HazanPrinceton neurips.cc/virtual/2023/p… SoNew: @Devvrit_Khatri @dvsaisurya @GuptaVineetG Cho-Jui Hsieh, @inderjit_ml neurips.cc/virtual/2023/p…

@roydanroy @HazanPrinceton @aminkarbasi @bremen79 Thank you @roydanroy! I’d love to visit, even if it’s winter! 🙂

@HazanPrinceton @aminkarbasi @bremen79 @XinyiChen2 Oh it's mild right now! But yeah, what I'd actually love to do is have her up for three talks over three days, and make an event around it.

I really like this paper. The idea is amazing. I am a bit disappointed that I have not thought about it myself. openreview.net/pdf?id=bOQNd7t…
