Perception, Reason, Think, and Plan: A Survey on Large Multimodal Reasoning Models

1 code implementation8 May 2025 Yunxin Li, Zhenyu Liu, Zitao Li, Xuanyu Zhang, Zhenran Xu, Xinyu Chen, Haoyuan Shi, Shenyuan Jiang, Xintong Wang, Jifang Wang, Shouzheng Huang, Xinping Zhao, Borui Jiang, Lanqing Hong, Longyue Wang, Zhuotao Tian, Baoxing Huai, Wenhan Luo, Weihua Luo, Zheng Zhang, Baotian Hu, Min Zhang

Large Multimodal Reasoning Models (LMRMs) have emerged as a promising paradigm, integrating modalities such as text, images, audio, and video to support complex reasoning capabilities and aiming to achieve comprehensive perception, precise understanding, and deep reasoning.

Take Off the Training Wheels Progressive In-Context Learning for Effective Alignment

1 code implementation13 Mar 2025 Zhenyu Liu, Dongfang Li, Xinshuo Hu, Xinping Zhao, Yibin Chen, Baotian Hu, Min Zhang

We find that the transformer embeds the task function learned from demonstrations into the separator token representation, which plays an important role in the generation of prior response tokens.

RaSeRec: Retrieval-Augmented Sequential Recommendation

1 code implementation24 Dec 2024 Xinping Zhao, Baotian Hu, Yan Zhong, Shouzheng Huang, Zihao Zheng, Meng Wang, Haofen Wang, Min Zhang

Although prevailing supervised and self-supervised learning (SSL)-augmented sequential recommendation (SeRec) models have achieved improved performance with powerful neural network architectures, we argue that they still suffer from two limitations: (1) Preference Drift, where models trained on past data can hardly accommodate evolving user preference; and (2) Implicit Memory, where head patterns dominate parametric learning, making it harder to recall long tails.

SEER: Self-Aligned Evidence Extraction for Retrieval-Augmented Generation

no code implementations15 Oct 2024 Xinping Zhao, Dongfang Li, Yan Zhong, Boren Hu, Yibin Chen, Baotian Hu, Min Zhang

Recent studies in Retrieval-Augmented Generation (RAG) have investigated extracting evidence from retrieved passages to reduce computational costs and enhance the final RAG performance, yet it remains challenging.

Enhancing Attributed Graph Networks with Alignment and Uniformity Constraints for Session-based Recommendation

1 code implementation14 Oct 2024 Xinping Zhao, Chaochao Chen, Jiajie Su, Yizhao Zhang, Baotian Hu

In this paper, we propose a model-agnostic framework, named AttrGAU (Attributed Graph Networks with Alignment and Uniformity Constraints), to bring the MIA's superiority into existing attribute-agnostic models, to improve their accuracy and robustness for recommendation.

FunnelRAG: A Coarse-to-Fine Progressive Retrieval Paradigm for RAG

no code implementations14 Oct 2024 Xinping Zhao, Yan Zhong, Zetian Sun, Xinshuo Hu, Zhenyu Liu, Dongfang Li, Baotian Hu, Min Zhang

In this work, we propose a progressive retrieval paradigm with coarse-to-fine granularity for RAG, termed FunnelRAG, so as to balance effectiveness and efficiency.

Bootstrapping Contrastive Learning Enhanced Music Cold-Start Matching

no code implementations5 Aug 2023 Xinping Zhao, Ying Zhang, Qiang Xiao, Yuming Ren, Yingchun Yang

In short, given a cold-start song request, we expect to retrieve songs with similar audiences and then fastly push the cold-start song to the audiences of the retrieved songs to warm up it.
