RL researcher. Opinions are my own.
Attending #ICLR2025 from 4/23 to 4/28 & will present PrefEval (prefeval.github.io) discussing the performance of SoTA LLMs on personalization. Catch our presentations on April 26th: 🔥Oral: 10:42-10:54am @ Hall 1 Apex 📊 Poster #558: 3:00-5:30pm @ Hall 3 + Hall 2B…
Excited to release PrefEval (ICLR '25 Oral), a benchmark for evaluating LLMs’ ability to infer, memorize, and adhere to user preferences in long-context conversations! ⚠️We find that cutting-edge LLMs struggle to follow user preferences—even in short contexts. This isn't just…
🚨🚨🚨 What to do when pre-training ends? Excited to share our latest work Proposer-Agent-Evaluator (PAE), where we trained an open-source SOTA generalist VLM web agent entirely with self-generated data and autonomous RL. Infrastructure and model fully open-sourced. (1/9)
I am presenting a paper from my last year's Amazon internship at IROS 2022, in which we handle long-horizon planning for home-assistant virtual robots with better semantic representation and exploration strategy. zjia.eng.ucsd.edu/amslam #IROS2022
I'm on the academic job market this year! I develop machine learning methods that are robust and adaptable to distribution shifts and open/non-stationary environments, w/ interdisciplinary applications in healthcare+drug discovery, transportation, and education. RT appreciated.
Amazon and @UCLA announced the establishment of the Science Hub for Humanity and Artificial Intelligence. The collaboration will support research, education & outreach efforts in areas of mutual interest around #AI and its applications to benefit humanity. amazon.science/academic-engag…
A late personal update: I'm now a tenure-track assistant professor at the New Jersey Institute of Technology (NJIT). Fresh new start! And I'm looking for prospective students interested in RL/DM/Transportation for Spring/Fall 2022. web.njit.edu/~hw32
🚨Postdoc opportunity🚨 in my group @nds_vu on topics in social network analysis! Please get in touch with me via email asap! We especially encourage applicants who are members of underrepresented groups (including those who identify as neurodivergent). 📢 Please RT!
Please see the link below if seeking a PhD position starting Fall 2021 or Spring 2022 in “...data mining and machine learning research, especially in graph neural networks and social network analysis.” You can follow Yao @ma_yao_ cse.msu.edu/~mayao4/openni…
We are pleased to announce that our very own Yao Ma will be joining the Department of Computer Science at New Jersey Institute of Technology (NJIT) as an Assistant Professor (tenure-track) in Fall 2021. Congratulations to Yao on his new position, it's truly a well deserved! 🥳

Excited to share that our paper "Linear Convergent Decentralized Optimization with Compression" has been accepted in ICLR 2021 openreview.net/forum?id=84gjU… Thank the reviewers/ACs and our collaborators @tangjiliang, @MingYan08, Yao Li, Rongrong Wang
Our paper "Linear Convergent Decentralized Optimization with Compression" is online at arxiv.org/pdf/2007.00232… This is the first algorithm achieving linear convergence with communication compression in decentralized optimization. Welcome to check it!
Very happy to have my previous collaborator @iftenney at @GoogleAI to give a talk at the Stanford NLP seminar this Thursday! Gonna be exciting!
We’re very excited to kick off our 2021 Stanford NLP Seminar series with Ian Tenney (@iftenney) of Google Research presenting on “BERTology and Beyond”! Thursday 10am PT. Open to the public non-Stanford people register at nlp.stanford.edu/seminar
Reinforcement Learning Day 2021 will feature a lively debate between Prof Yoshua Bengio from @Mila_Quebec and Dr. @JohnCLangford. Reserve your seat now to watch their discussion on “The State of RL and The Theory-Practice Divide” on January 14 at 11 AM: aka.ms/AAae0zv
📣[DeepRobust-0.1.1 Comes Out!] Our PyTorch library for adversarial robustness on graph and image data, DeepRobust, can now be installed from pip! Just try `pip install deeprobust`. For more details, please visit github.com/DSE-MSU/DeepRo…! #MachineLearning #python #DeepLearning
What a comprehensive collection of simulation platforms for embodied AI and RL! Add two more: aihabitat.org and svl.stanford.edu/igibson/
Some simulation platforms that caught my eye this year 🧵
Embodied & Teachable AI team at Amazon Alexa AI is looking for multiple research interns starting summer 2021. Please feel free to contact me if you are interested in Human-robot interaction, VQA, VLN, etc. #internship #machinelearning #AI #Amazon
