DynThinker: Unifying Static 3D and Dynamic 4D Spatial Reasoning

Qihang Cao, Haoyuan Li, Zihan Guo +8

Achieving general spatial intelligence requires a unified understanding of both static 3D and dynamic 4D. However, we find that existing models struggle to excel at both: 3D post-t…

Probabilistic Residual Learning for Online Recommendations

Wenyuan Wang, Yusong Zhao, Zihao Xu +11

Modern recommender systems are typically based on deep learning (DL) models, where a dense encoder learns representations of users and items. As a result, these systems often suffe…

ExpWeaver: LLM Agents Learn from Experience via Latent RAG

Tao Feng, Tianyang Luo, Jingjun Xu +5

Experience learning has achieved promising results in enhancing LLM agent planning and reasoning by integrating past interactions as reusable knowledge. However, existing methods r…

ExpHarness: Model-Agnostic Experience Learning through a Trainable Harness

Tao Feng, Chongrui Ye, Fangxu Yu +11

Large language model (LLM) agents increasingly operate within a harness, the scaffolding that determines what enters the executor's context, yet the experience they accumulate acro…

LRanker: Scaling LLM Ranking to Millions of Candidates with Test-Time Scaling

Tao Feng, Zijie Lei, Zhigang Hua +4

Large language models (LLMs) offer strong semantic representations for ranking, but processing candidate texts within limited contexts and repeatedly invoking an LLM for candidate-…

MemReward: Graph-Based Experience Memory for LLM Reward Prediction with Limited Labels

Tianyang Luo, Tao Feng, Zhigang Hua +4

Reinforcement learning has emerged as a powerful paradigm for improving large language model (LLM) reasoning, where rollouts are sampled from the policy and reward signals computed…

UniRec: Unified Multimodal Encoding for LLM-Based Recommendations

Zijie Lei, Tao Feng, Zhigang Hua +5

Large language models have recently shown promise for multimodal recommendation, particularly with text and image inputs. Yet real-world recommendation signals extend far beyond th…
