I’m happy and grateful to share that I’ve started my PhD @NUSingapore under the @AISingapore PhD Fellowship!

First up a hackathon: 20+ researchers · two weeks · @OxfordStats × @NUSComputing × @NTUsg and tokens on tap by @AnthropicAI .
Outcome: Five open‑source AI agents solving common workflow frustrations across the whole research lifecycle. 🧵

🎉Excited to share our new work: "StochasTok: Improving Fine-Grained Subword Understanding in LLMs"!🎉
We rethink tokenization and allow LLMs to ‘see inside’ individual tokens by stochastically splitting them into equivalent pairs. See👇!
Thanks to my incredible co-authors!🥰
🚀Introducing “StochasTok: Improving Fine-Grained Subword Understanding in LLMs”!🚀
LLMs are incredible but still struggle disproportionately with subword tasks, e.g., for character counts, wordplay, multi-digit numbers, fixing typos… Enter StochasTok, led by @anyaasims!

🚨My awesome labmate Yiran
@yiran_zhao924
is presenting our #ACL2024NLP poster: “Prompt Optimization via Adversarial In-context Learning”.
🚀 Want to chat about optimising LLM hard prompts by Adv. Learning?
🌟Please check out his presentation on Tue. 5-6pm, Poster Sec. 5!

My DGX Station is the most gorgeous piece of technology that I’ve ever had.

The rise of LLMs has been the main push for the adoption of vector databases. Turning text (or even multimodal) data into an embedding vector can significantly improve performance of any AI application. However, it is quite possible that we can get even better performance if we first build that basis workhorse of the Internet era - a search engine.

📢 My book on Fairness and ML with @s010n and Moritz Hardt has been published by @mitpress! mitpress.mit.edu/97802620486…
The draft (fairmlbook.org) has already been used in many courses. We've also released a set of exercises and discussion prompts: docs.google.com/document/d/1…

We have been working on fairness problems in federated learning. We showed that FL may propagate bias from the most biased parties to the less biased parties. Check our paper here arxiv.org/abs/2309.02160 and a blog post here montrealethics.ai/bias-propa….

I'm happy to announce the start of a new free and open online course on neuroscience for people with a machine learning or similar background, co-developed by @MarcusGhosh. YouTube Videos and Jupyter-based exercises will be released weekly. There is a Discord for discussions.

Hey! I'm so glad you found this exciting -- I've been really excited about how it might help and delighted to be able to share it.
With that said, I do want to caution that a lot of work remains to be done.

Why does this read to me as "Just grab VC money without building usable and scalable products"? Maybe I am missing something.

New paper! We ask: How important is VQ for neural discrete representation learning? 🤔
I always felt it should be possible to “absorb” the VQ on top of a deep net into the net and use a simple grid-based quantization instead, without sacrificing much expressivity.

I ask DALLE-3 to generate a Pepe but each time I tell it to make it "more rare."

Here's a tutorial that I wrote about training and fine-tuning LLMs. I try to make the motivation and details of RLHF clearer and discuss a new method called direct preference optimization.
