STRUCTUREDAGENT: Planning with AND/OR Trees for Long-Horizon Web Tasks

ELita Lobo, Xu Chen, Jingjing Meng +5

Recent advances in large language models (LLMs) have enabled agentic systems for sequential decision-making. Such agents must perceive their environment, reason across multiple tim…

Towards AI Transparency and Accountability: A Global Framework for Exchanging Information on AI Systems

Warren Buckley, Adrian Byrne, Nicholas Perello +4

We propose that future AI transparency and accountability regulations are based on an open global standard for exchanging information about AI systems, which allows co-existence of…

Cumulative Games: Who is the current player?

Urban Larsson, Reshef Meir, Yair Zick

Combinatorial Game Theory(CGT)is a branch of Game Theory that has developed largely independently of Economic Game Theory (EGT), and is concerned with deep mathematical properties…

Hedonic Neurons: A Mechanistic Mapping of Latent Coalitions in Transformer MLPs

Tanya Chowdhury, Atharva Nijasure, Yair Zick +1

Fine-tuned Large Language Models (LLMs) encode rich task-specific features, but the form of these representations, especially within MLP layers, remains unclear. Empirical inspecti…

Stable Matching under Matroid Rank Valuations

Alon Eden, Vignesh Viswanathan, Yair Zick

We study a two-sided matching model where one side of the market (hospitals) has combinatorial preferences over the other side (doctors). Specifically, we consider the setting wher…

Heterogeneous Multi-Agent Bandits with Parsimonious Hints

Amirmahdi Mirfakhar, Xuchuang Wang, Jinhang Zuo +2

We study a hinted heterogeneous multi-agent multi-armed bandits problem (HMA2B), where agents can query low-cost observations (hints) in addition to pulling arms. In this framework…
