Seeing, Maintaining, and Learning: The Evolution of Multimodal Agent Memory

Minghao Guo, Qingyue Jiao, Xiujin Liu +77

Multimodal models and agents have emerged to enable AI systems to learn from and interact with the real world more like humans by integrating information across multiple modalities…

Pack Light, CarryOn: Building Object-Oriented Context for Long-Horizon Agents

Yuchen Lu, Julian McAuley, Lei Zhang

Long-horizon agents accumulate progress in persistent task state, yet repeatedly process interaction histories describing how that progress was achieved. This raises a natural ques…

Self-Retrospection Distillation: Turning Post-hoc Experiences into Prior Foresight

Haoxiang Zhang, Qinglin Chen, Hiroaki Hayashi +9

Reinforcement learning with verifiable rewards (RLVR) turns agent experience into learning signals primarily through scalar outcome rewards after interaction. For group-relative ob…

Spurious Tool Use: When RL Agents Learn the Wrong Reason to Act

Yiwei Yang, Haoxiang Zhang, Bingbing Wen +6

Large language model (LLM) agents increasingly interleave natural language reasoning with external tools such as web search and code execution. These tool-use policies are often op…

Agentic Commerce World: An Auditable and Verifiable Environment for Vibe Commerce

Shicheng Fan, Mingdai Yang, Duohao Wang +9

In vibe coding, people describe software in natural language and delegate implementation to AI agents. By analogy, vibe commerce allows people to express buying or selling goals in…

Masking Stale Observations Helps Search Agents -- Until It Doesn't: A Regime Map and Its Mechanism

Haoxiang Zhang, Qixin Xu, Zhuofeng Li +4

Long-horizon search agents accumulate large amounts of retrieved content across many tool calls, making context-budget efficiency increasingly important. A minimal intervention is…

On Generalization in Agentic Tool Calling: CoreThink Agentic Reasoner and MAVEN Dataset

Vishvesh Bhat, Omkar Ghugarkar, Julian McAuley

Generalization across Agentic tool-calling environments remains a key unsolved challenge in developing reliable agentic reasoning systems. While large language models (LLMs) demons…

CoreThink: A Symbolic Reasoning Layer to reason over Long Horizon Tasks with LLMs

Jay Vaghasiya, Omkar Ghugarkar, Vishvesh Bhat +2

We introduce CoreThink, a state-of-the-art Reasoning Layer built upon a novel reasoning method called General Symbolics. This approach diverges from reasoning paradigms such as tes…

GSPRec: On Improving Item Representations in Graph Signal Processing for Collaborative Filtering

Ahmad Bin Rabiah, Julian McAuley

Graph-based collaborative filtering methods act as low-pass filters in the spectral domain and discard the intermediate-frequency components where community-level user preferences…
