Autoregressive Retriever: Improving Query Understanding from Item Feedback for Universal Multimodal Retrieval

Jianfei Zhao, Yifan Wang, Feng Zhang وآخرون · 2026

Universal multimodal retrieval typically encodes a query once and ranks independently indexed items by embedding similarity. This design supports efficient search, but leaves the query representation unchanged even when retrieved items could help clarify the information need. We introduce the AutoRegressive Retriever ( …

Robust Tensor Completion via Reflective Convolution Nuclear Norm Minimization

Weiguo Zhou, Feng Zhang, Wenjin Qin وآخرون · 2026

Robust tensor completion recovers multidimensional data from partial observations corrupted by sparse gross errors. Existing convolutional low-rank models typically construct translated copies using circular continuation, which introduces artificial wrap-around neighborhoods for finite nonperiodic data. We propose refl …
