PhotoCraft: Agentic Reasoning with Hierarchical Self-Evolving Memory for Deep Image Search

Kailin Lyu, Zhiqiang Yuan, Jianwei He +9

Deep Image Search requires multi-step reasoning over rich contextual cues, such as time, location, and event relations. However, most existing LLM-based agents are stateless and re…

MemMark: State-Evolution Attribution Watermarking for Agent Long-Term Memory Systems

Haobo Zhang, Xutao Mao, Guangyuan Dong +5

Memory-backed agents need provenance that can survive leaked or migrated snapshots, where logs, visible outputs, and trusted metadata may be absent. We propose MemMark, a state-evo…

Sell More, Play Less: Benchmarking LLM Realistic Selling Skill

Xuanbo Su, Wenhao Hu, Haibo Su +4

Sales dialogues require multi-turn, goal-directed persuasion under asymmetric incentives, which makes them a challenging setting for large language models (LLMs). Yet existing dial…

ROAST: Rollout-based On-distribution Activation Steering Technique

Xuanbo Su, Hao Luo, Yingfang Zhang +1

Activation steering provides parameter-efficient control over large language models (LLMs) at inference time, but many methods rely on off-distribution supervision and discrete mas…

Mistake Notebook Learning: Batch-Clustered Failures for Training-Free Agent Adaptation

Xuanbo Su, Yingfang Zhang, Hao Luo +2

With the growing adoption of Large Language Model (LLM) agents in persistent, real-world roles, they naturally encounter continuous streams of tasks and inevitable failures. A key…
