I am a postdoc at the Mosaic team at AI2 and an incoming assistant professor at the University of Waterloo. My research interests are Natural Language Processing and Machine Learning. I also enjoy building demos such as Grade School Math Solver w/o CoT, Multiplication Predictor w/o CoT, WildChat Visualizer, OpenAI Watch, Linguistic Steganography, AKSelectionPredictor, OpenNMT, Markup-to-Image Diffusion, and Image-to-Markup.


News

  • July 11, 2024: I built a demo to solve grade school math problems (GSM8K) without chain-of-thought (CoT) at 52% accuracy. CoT is internalized using the approach in From Explicit CoT to Implicit CoT: Learning to Internalize CoT Step by Step. Surprisingly, it even works in languages not used during internalization finetuning!
  • June 28, 2024: I built a demo using GPT-2 to directly produce the product of two numbers (up to 15 digits) without chain-of-thought (CoT). CoT is internalized using the approach in From Explicit CoT to Implicit CoT: Learning to Internalize CoT Step by Step. A 12-layer GPT-2 can solve 15-digit multiplication very well!
  • June 19, 2024: I built a website, wildchat.yuntiandeng.com, for interactive search of WildChat, allowing keyword, toxicity, IP, language, and country-based searches of 1M WildChat conversations.
  • May 29, 2024: Our paper, From Explicit CoT to Implicit CoT: Learning to Internalize CoT Step by Step, is now publicly available! This paper proposes a simple yet effective method to teach language models to internalize chain-of-thought reasoning by gradually removing intermediate steps and finetuning.
  • Apr 26, 2024: I built a demo, AKSelectionPredictor, to predict whether a paper will be selected by @_akhaliq into Hugging Face papers based on its title, abstract, and authors.
  • Mar 5, 2024: Our dataset, WildChat, is used in Anthropic's Claude 3 for evaluating refusals.
  • Nov 14, 2023: Our dataset, WildChat, is now publicly available! It is a corpus of 650K real-world user-ChatGPT interactions, characterized by over 60 languages and a diversity of user prompts.
  • Nov 7, 2023: Our paper, Implicit Chain of Thought Reasoning via Knowledge Distillation, is now publicly available! This paper trains LMs that can reason internally using hidden states instead of articulating all reasoning steps like humans.
  • Mar 29, 2023: OpenAIWatch.com is launched! It tracks GPT-4's nondeterministic behavior even with greedy decoding in unicorn illustrations. 🦄
  • Mar 29, 2023: Our GPT Chatbot, based on Yuvraj Sharma's code, is now live! It provides free acess to GPT with the aim of collecting dialogue data for research purposes.
  • Oct 18, 2022: Our paper, Model Criticism for Long-Form Text Generation, is now publicly available! This paper uses model criticism in latent space to quantify various notions of high-level coherence in long-form text generation.
  • Oct 12, 2022: Markup-to-Image Diffusion Models demo is now live! This project uses a diffusion model to learn how to render various types of markups, including LaTeX.
  • Jun 2, 2020: Our paper, Cascaded Text Generation with Markov Transformers, is available! It allows parallel, fast, autoregressive, and accurate text generation using a high-order Markov model.
  • Apr 26, 2020: Introducing Residual Energy-Based Models for Text Generation, a globally-normalized approach to text generation! Our approach uses a global discriminator to guide the traditional locally-normalized language model to produce text that's more indistinguishable from human-written text.
  • Sep 5, 2019: Neural Linguistic Steganography demo is now live! This project lets you hide secret messages in natural language using arithmetic coding.
  • Dec 19, 2016: Excited to introduce OpenNMT, an open-source neural machine translation toolkit developed for industrial and academic use.
  • Sep 19, 2016: Excited to announce that we've provided a solution to OpenAI's requests-for-research im2latex challenge using neural sequence-to-sequence learning! Check out the visualizations here.
