Closing the Indexing-Decoding Gap in Multimodal Generative Retrieval via Prefix Retention Optimization

Yufei Chen, Zihan Wang, Yubao Tang +3

Multimodal generative retrieval formulates multimodal retrieval as discrete identifier generation, eliminating the need for explicit similarity search over external embeddings. Exi…

When Tools Fail: Benchmarking Dynamic Replanning and Anomaly Recovery in LLM Agents

Dongsheng Zhu, Xuchen Ma, Yucheng Shen +5

Existing benchmarks evaluate Tool-Integrated Reasoning (TIR) in LLMs on idealized ''happy paths'', largely overlooking real-world tool failures. We introduce ToolMaze, a benchmark…

Joint Flashback Adaptation for Forgetting-Resistant Instruction Tuning

Yukun Zhao, Lingyong Yan, Zhenyang Li +4

Large language models have achieved remarkable success in various tasks. However, it is challenging for them to learn new tasks incrementally due to catastrophic forgetting. Existi…

DiffuGR: Generative Document Retrieval with Diffusion Language Models

Xinpeng Zhao, Zhaochun Ren, Yukun Zhao +9

Generative retrieval (GR) reframes document retrieval as an end-to-end task of generating sequential document identifiers (DocIDs). Existing GR methods predominantly rely on left-t…

GRAF: Multi-turn Jailbreaking via Global Refinement and Active Fabrication

Hua Tang, Lingyong Yan, Yukun Zhao +3

Large Language Models (LLMs) have demonstrated remarkable performance across diverse tasks. Nevertheless, they still pose notable safety risks due to potential misuse for malicious…
