Regression of Instance Boundary by Aggregated CNN and GCN

no code implementations ECCV 2020 Yanda Meng, Wei Meng, Dongxu Gao, Yitian Zhao, Xiaoyun Yang, Xiaowei Huang, Yalin Zheng

In particular, thanks to the proposed aggregation GCN, our network benefits from direct feature learning of the instances’ boundary locations and the spatial information propagation across the image.

Incomplete Modality Disentangled Representation for Ophthalmic Disease Grading and Diagnosis

no code implementations17 Feb 2025 Chengzhi Liu, Zile Huang, Zhe Chen, Feilong Tang, Yu Tian, Zhongxing Xu, Zihong Luo, Yalin Zheng, Yanda Meng

To address these, we propose an Incomplete Modality Disentangled Representation (IMDR) strategy, which disentangles features into explicit independent modal-common and modal-specific features by guidance of mutual information, distilling informative knowledge and enabling it to reconstruct valuable missing semantics and produce robust multimodal representations.

Self-adaptive vision-language model for 3D segmentation of pulmonary artery and vein

no code implementations7 Jan 2025 Xiaotong Guo, Deqian Yang, Dan Wang, Haochen Zhao, Yuan Li, Zhilin Sui, Tao Zhou, Lijun Zhang, Yanda Meng

Exploiting the generalization ability of these pre-trained foundation models on downstream tasks, such as segmentation, leads to unexpected performance with a relatively small amount of labeled data.

Uncertainty is Fragile: Manipulating Uncertainty in Large Language Models

2 code implementations15 Jul 2024 Qingcheng Zeng, Mingyu Jin, Qinkai Yu, Zhenting Wang, Wenyue Hua, ZiHao Zhou, Guangyan Sun, Yanda Meng, Shiqing Ma, Qifan Wang, Felix Juefei-Xu, Kaize Ding, Fan Yang, Ruixiang Tang, Yongfeng Zhang

We demonstrate that an attacker can embed a backdoor in LLMs, which, when activated by a specific trigger in the input, manipulates the model's uncertainty without affecting the final output.

Exploring Concept Depth: How Large Language Models Acquire Knowledge at Different Layers?

1 code implementation10 Apr 2024 Mingyu Jin, Qinkai Yu, Jingyuan Huang, Qingcheng Zeng, Zhenting Wang, Wenyue Hua, Haiyan Zhao, Kai Mei, Yanda Meng, Kaize Ding, Fan Yang, Mengnan Du, Yongfeng Zhang

In this paper, we explore the hypothesis that LLMs process concepts of varying complexities in different layers, introducing the idea of ``Concept Depth'' to suggest that more complex concepts are typically acquired in deeper layers.

Health-LLM: Personalized Retrieval-Augmented Disease Prediction System

no code implementations1 Feb 2024 Qinkai Yu, Mingyu Jin, Dong Shu, Chong Zhang, Lizhou Fan, Wenyue Hua, Suiyuan Zhu, Yanda Meng, Zhenting Wang, Mengnan Du, Yongfeng Zhang

Recent advancements in artificial intelligence (AI), especially large language models (LLMs), have significantly advanced healthcare applications and demonstrated potentials in intelligent medical treatment.

The Impact of Reasoning Step Length on Large Language Models

2 code implementations10 Jan 2024 Mingyu Jin, Qinkai Yu, Dong Shu, Haiyan Zhao, Wenyue Hua, Yanda Meng, Yongfeng Zhang, Mengnan Du

Alternatively, shortening the reasoning steps, even while preserving the key information, significantly diminishes the reasoning abilities of models.

Automatically Segment the Left Atrium and Scars from LGE-MRIs Using a Boundary-focused nnU-Net

no code implementations27 Apr 2023 Yuchen Zhang, Yanda Meng, Yalin Zheng

Accurate segmentation of the left atrial (LA) and LA scars can provide valuable information to predict treatment outcomes in AF.

3D Dense Face Alignment with Fused Features by Aggregating CNNs and GCNs

no code implementations9 Mar 2022 Yanda Meng, Xu Chen, Dongxu Gao, Yitian Zhao, Xiaoyun Yang, Yihong Qiao, Xiaowei Huang, Yalin Zheng

In this paper, we propose a novel multi-level aggregation network to regress the coordinates of the vertices of a 3D face from a single 2D image in an end-to-end manner.

Spatial Uncertainty-Aware Semi-Supervised Crowd Counting

1 code implementation ICCV 2021 Yanda Meng, Hongrun Zhang, Yitian Zhao, Xiaoyun Yang, Xuesheng Qian, Xiaowei Huang, Yalin Zheng

Semi-supervised approaches for crowd counting attract attention, as the fully supervised paradigm is expensive and laborious due to its request for a large number of images of dense crowd scenarios and their annotations.
