EFUF: Efficient Fine-grained Unlearning Framework for Mitigating Hallucinations in Multimodal Large Language Models

no code implementations15 Feb 2024 Shangyu Xing, Fei Zhao, Zhen Wu, Tuo An, WeiHao Chen, Chunhui Li, Jianbing Zhang, Xinyu Dai

Multimodal large language models (MLLMs) have attracted increasing attention in the past few years, but they may still generate descriptions that include objects not present in the corresponding images, a phenomenon known as object hallucination.

Deep-Learning-based Vasculature Extraction for Single-Scan Optical Coherence Tomography Angiography

no code implementations17 Apr 2023 Jinpeng Liao, Tianyu Zhang, Yilong Zhang, Chunhui Li, Zhihong Huang

In comparison to OCTA images obtained via the SV-OCTA (PSNR: 17. 809) and ED-OCTA (PSNR: 18. 049) using four-repeated OCT scans, OCTA images extracted by VET exhibit moderate quality (PSNR: 17. 515) and higher image contrast while reducing the required data acquisition time from ~8 s to ~2 s. Based on visual observations, the proposed VET outperforms SV and ED algorithms when using neck and face OCTA data in areas that are challenging to scan.

EPCS: Endpoint-based Part-aware Curve Skeleton Extraction for Low-quality Point Clouds

no code implementations17 Nov 2022 Chunhui Li, Mingquan Zhou, Zehua Liu, Yuhe Zhang

In this study, the endpoint-based part-aware curve skeleton (EPCS) extraction method for low-quality point clouds is proposed.

An Unsupervised Learning Approach for Spectrum Allocation in Terahertz Communication Systems

no code implementations7 Aug 2022 Akram Shafie, Chunhui Li, Nan Yang, Xiangyun Zhou, Trung Q. Duong

Numerical results demonstrate that comparing to existing approaches, our proposed unsupervised learning-based approach achieves a higher data rate, especially when the molecular absorption coefficient within the spectrum of interest varies in a highly non-linear manner.
