Ask any LLM for a single fact and it’s usually fine.
Ask it for a rich list and the same fact is suddenly missing or hallucinated because the output context got longer 😳

LLMs exceed 80% accuracy on single-value questions but accuracy drops linearly with the # of output facts

🌟 New paper alert! 🌟
Our paper, "Retrieve, Merge, Predict: Augmenting Tables with Data Lakes", has been published in TMLR!
In this work, we created YADL (a semi-synthetic data lake), and we benchmarked methods for augmenting user-provided tables given information found in data lakes.

Think2SQL: Bridging the Reasoning Gap in Text-to-SQL for Small LLMs

Leveraging RL with our reward mechanism, we push Qwen-Coder-2.5 7B to performance on par with much larger LLMs (>400B) on the BIRD dataset! 🤯

🗜️New LLM compression paper "Beyond RAG: Task-Aware KV Cache Compression for Comprehensive Knowledge Reasoning"
RAG struggles with broad, multi-hop questions.
We surpass RAG by up to 20 absolute points in QA performance, even with extreme cache compression (64x smaller)!

NOVAS is a new venue for your paper bridging the gap between data management and generative AI research!
It will be in Berlin, June 22th, together with @sigmod2025.bsky.social
Submission deadline: 28 March 2025

Tropes, such as "Hidden Motives", are recurring narrative elements used to evoke familiar patterns in communication

Our #COLING paper uncovers that tropes are used in 37% of the social posts debating immigration and vaccination

Meta is also embracing Community Notes (as now branded on X), the crowdsourcing approach to fact-checking on social networks.
We have audited the program when it was called Birdwatch and found both promising results and concerning manipulation risks. More details below.👇

🚀 Up to 93x input compression for LLMs!
By compressing the data in the KV cache, we squeeze more info in the context.

Hi everyone!
I'm a professor in the Data Science department at EURECOM, France. 🎓
My research focuses on data management and LLMs to enhance information quality, including data cleaning and misinformation detection.
I'm here mostly for the research, but I occasionally comment on sports and arts.
