PACER: Acyclic Causal Discovery from Large-Scale Interventional Data

Ramon Viñas Torné, Sílvia Fà bregas Salazar, Soyon Park +4

Inferring the structure of directed acyclic graphs (DAGs) from data is a central challenge in causal discovery, particularly in modern high-dimensional settings where large-scale i…

Meta-RL Induces Exploration in Language Agents

Yulun Jiang, Liangze Jiang, Damien Teney +2

Reinforcement learning (RL) has enabled the training of large language model (LLM) agents to interact with the environment and to solve multi-turn long-horizon tasks. However, the…

When Weak LLMs Speak with Confidence, Preference Alignment Gets Stronger

Amirabbas Afzali, Myeongho Jeon, Maria Brbic

Preference alignment is an essential step in adapting large language models (LLMs) to human values, but existing approaches typically depend on costly human annotations or large-sc…

Large (Vision) Language Models are Unsupervised In-Context Learners

Artyom Gadetsky, Andrei Atanov, Yulun Jiang +4

Recent advances in large language and vision-language models have enabled zero-shot inference, allowing models to solve new tasks without task-specific training. Various adaptation…
