Uniform Local Asymptotics for Lévy Processes with Subexponential Jumps
Hao Wu, Wei Xu
This paper is devoted to unifying the uniform local large-deviation asymptotics for a centered Lévy process with subexponential jumps. Our results assert that for any …
Diarization-Guided Qwen-ASR Adaptation for Multilingual Two-Speaker Conversational Speech
Hao Wu, RongQi Han, Zhen Wang +2
This paper describes our self-designed system for Task 1 of the MLC-SLM 2026 Challenge for multilingual two-speaker conversational speech. The system combines a modular speaker dia…
Large Excursions of Reflected Lévy Processes: Asymptotic Shapes
Zhi-Hao Cui, Hao Wu, Wei Xu
This paper primarily investigates the geometric properties of excursions of Lévy processes reflected at the past infimum with long lifetime or large height. For an oscillating proc…
Nuclear Ptychoscopy: A Ptychographic Framework for Nuclear Spectroscopy
Ziyang Yuan, Yifei Zhang, Yonggong Teng +16
Accessing both amplitude and phase of nuclear response functions is central to fully characterizing light-matter interactions in the X-ray-nuclear regime. Recent work has demonstra…
ILT-Iterative LoRA Training through Focus-Feedback-Fix for Multilingual Speech Recognition
Qingliang Meng, Hao Wu, Wei Liang +2
The deep integration of large language models and automatic speech recognition systems has become a promising research direction with high practical value. To address the overfitti…
