miniReranker: Efficient Multimodal Reranking through Visual Cache Reuse and Interaction Sparsity

Yingqi Fan, Xuan Lu, Anhao Zhao +6

Multimodal large language models (MLLMs) have recently shown strong potential as point-wise rerankers by directly modeling query--document relevance through next-token prediction.…

PowerOPD: Stabilizing On-Policy Distillation with Bounded Power Transformation

Anhao Zhao, Junlong Tong, Yingqi Fan +3

Standard on-policy distillation (OPD) for large language models estimates the reverse-KL objective using student-sampled tokens, yielding an unbiased single-sample Monte Carlo esti…

AdaSR: Adaptive Streaming Reasoning with Hierarchical Relative Policy Optimization

Junlong Tong, Wenqi Xu, Yingqi Fan +4

Large reasoning models typically follow a read-then-think paradigm: they observe the complete input, reason over a static context, and then produce the answer. Yet many real-world…

CompRank: Efficient LLM Reranking via Token-Level Compression and Decoding-Free Scoring

Xuan Lu, Haohang Huang, Yingqi Fan +5

Large language model (LLM) rerankers have become an important component of modern retrieval and retrieval-augmented generation pipelines, but their high computational cost limits t…

ProactiveLLM: Learning Active Interaction for Streaming Large Language Models

Junlong Tong, Yao Zhang, Anhao Zhao +3

Standard Large Language Models (LLMs) follow a read-then-generate paradigm, causing unnecessary latency and computation. Streaming LLMs alleviate this issue by generating while rec…

ViCA: Efficient Multimodal LLMs with Vision-Only Cross-Attention

Wenjie Liu, Hao Wu, Xin Qiu +6

Modern multimodal large language models (MLLMs) adopt a unified self-attention design that processes visual and textual tokens at every Transformer layer, incurring substantial com…
