Beyond Type-checking: Towards Holistic Evaluation of Formal Specification Generation

Srijith Nair, Aditya Vempaty, Jia Liu وآخرون · 2026

When generating verifiable code, natural language requirements are mapped to machine checked code using LLMs and agentic workflows. A crucial component of this pipeline is specification generation (SpecGen), which produces a formal contract against which an agent can prove implementation correctness. Proof generation c …

Foundation Model-Aided Multi-Agent Reinforcement Learning for Wireless Random Access Network Optimization

Random access (RA) is one of the most foundational medium access control (MAC) layer scheduling schemes for handling unpredictable data traffic from multiple terminals. While multi-agent reinforcement learning (MARL) has been explored to optimize RA-based wireless networks, its reliance on experience-driven, distribute …

Towards One-for-All Foundation Model for Attributed Graph Clustering

Yunhui Liu, Xudong Jin, Kang Zhang وآخرون · 2026

Attributed graph clustering aims to discover node groups by jointly exploiting node attributes and graph topology, yet its unsupervised nature makes model selection and adaptation inherently difficult. Existing methods typically train and tune a separate model for each input graph, leading to costly and fragile pipelin …

Who Owns That? Evaluating Ownership Intuitions in Large Language Models

Xizhi Xiao, Yue Wu, Shan Xu وآخرون · 2026

Ownership establishes rights over the use, control, and transfer of objects. Understanding these relations is essential for AI systems to interact appropriately with people and their resources. Yet how large language models (LLMs) attribute ownership under competing claims remains unclear. We introduce the Competing Ow …

Do Motion Tokenizers for Co-Speech Gesture Generation Encode Gesture Semantics?

Varsha Suresh, Divij Jain, Jia Liu وآخرون · 2026

Discrete motion tokenizers encode motion as atomic units and are widely used for co-speech gesture generation. It remains unclear which motion properties, especially those relevant to gesture semantics, are recoverable from these codebooks. We probe a reconstruction-trained codebook using 19 co-speech gesture descripto …
