Fine-Tuning Vision-Language Models for Visual Navigation Assistance
Xiao Li, Bharat Gandhi, Ming Zhan +6
We address vision-language-driven indoor navigation to assist visually impaired individuals in reaching a target location using images and natural language guidance. Traditional na…
Sparsity-Promoting Dynamic Mode Decomposition Applied to Sea Surface Temperature Fields
Zhicheng Zhang, Yoshihiko Susuki, Atsushi Okazaki
In this paper, we leverage Koopman mode decomposition to analyze the nonlinear and high-dimensional climate systems acting on the observed data space. The dynamics of atmospheric s…
Approximation does not help in quantum unitary time-reversal
Kean Chen, Nengkun Yu, Zhicheng Zhang
Access to the time-reverse of an unknown quantum unitary process is widely assumed in quantum learning, metrology, and many-body physics. The fundamental task of unita…
Adaptive Differential Denoising for Respiratory Sounds Classification
Gaoyang Dong, Zhicheng Zhang, Ping Sun +1
Automated respiratory sound classification faces practical challenges from background noise and insufficient denoising in existing systems. We propose Adaptive Differential Denoisi…
Extracting transient Koopman modes from short-term weather simulations with sparsity-promoting dynamic mode decomposition
Zhicheng Zhang, Yoshihiko Susuki, Atsushi Okazaki
Convective features, represented here as warm bubble-like patterns, reveal essential high-level information about how short-term weather dynamics evolve within a high-dimensional s…
Hierarchical and Step-Layer-Wise Tuning of Attention Specialty for Multi-Instance Synthesis in Diffusion Transformers
Chunyang Zhang, Zhenhong Sun, Zhicheng Zhang +5
Text-to-image (T2I) generation models often struggle with multi-instance synthesis (MIS), where they must accurately depict multiple distinct instances in a single image based on c…
Flaming-hot Initiation with Regular Execution Sampling for Large Language Models
Weizhe Chen, Zhicheng Zhang, Guanlin Liu +6
Since the release of ChatGPT, large language models (LLMs) have demonstrated remarkable capabilities across various domains. A key challenge in developing these general capabilitie…
Autonomous Path Planning for Intercostal Robotic Ultrasound Imaging Using Reinforcement Learning
Yuan Bi, Cheng Qian, Zhicheng Zhang +2
Ultrasound (US) has been widely used in daily clinical practice for screening internal organs and guiding interventions. However, due to the acoustic shadow cast by the subcutaneou…
