Can LLM Agents Infer World Models? Evidence from Agentic Automata Learning

Reef Menaged, Gili Lior, Shauli Ravfogel +2

We propose agentic automata learning to evaluate the extent to which tool-calling LLM agents can uncover hidden environments through interaction. In our setup, an agent should unco…

Thinking to Recall: How Reasoning Unlocks Parametric Knowledge in LLMs

Zorik Gekhman, Roee Aharoni, Eran Ofek +3

While reasoning in LLMs plays a natural role in math, code generation, and multi-hop factual questions, its effect on simple, single-hop factual questions remains unclear. Such que…

Localizing Factual Inconsistencies in Attributable Text Generation

Arie Cattan, Paul Roit, Shiyue Zhang +5

There has been an increasing interest in detecting hallucinations in model-generated texts, both manually and automatically, at varying levels of granularity. However, most existin…

DoubleDipper: Improving Long-Context LLMs via Context Recycling

Arie Cattan, Alon Jacovi, Alex Fabrikant +8

Despite recent advancements in Large Language Models (LLMs), their performance on tasks involving long contexts remains sub-optimal. In this work, we propose DoubleDipper, a novel…

DRAGged into Conflicts: Detecting and Addressing Conflicting Sources in Search-Augmented LLMs

Arie Cattan, Alon Jacovi, Ori Ram +6

Retrieval Augmented Generation (RAG) is a commonly used approach for enhancing large language models (LLMs) with relevant and up-to-date information. However, the retrieved sources…

Representation Surgery: Theory and Practice of Affine Steering

Shashwat Singh, Shauli Ravfogel, Jonathan Herzig +3

Language models often exhibit undesirable behavior, e.g., generating toxic or gender-biased text. In the case of neural language models, an encoding of the undesirable behavior is…
