Strong Converse Exponents of Quantum Soft Covering and Privacy Amplification
Shi-Bing Li, Hongsen Qiu, Xinyu Zhang
We determine the exact strong converse exponent of quantum soft covering under the sandwiched R{é}nyi divergence for all orders . For $α\in[\frac{1}{2},1)…
QUMem: Personalized Memory for Query-Conditioned User-State Inference in LLM Agents
Heng Wang, Yifei Li, Lingling Zhang +4
Large language model (LLM) agents increasingly use external memory systems to support personalization by drawing on long and evolving interaction histories, in which user preferenc…
Gaussianization-Based Parameter Estimation for Gamma-Gamma and Lognormal-Rician Turbulence Channels
Maoke Miao, Bo Liu, Xinyu Zhang +1
Accurate parameter estimation for atmospheric turbulence channels is challenging because the probability density functions of the Gamma-Gamma (GG) and Lognormal-Rician (LR) models…
GLaQ: Grounding Latent Queries in Visual Evidence for Multimodal Reasoning
Zesheng Yang, Lingling Zhang, Xinyu Zhang +4
Chain-of-thought reasoning has substantially improved the problem-solving capabilities of multimodal large language models. Fine-grained visual evidence, however, remains difficult…
