Causal-SAM-LLM: Large Language Models as Causal Reasoners for Robust Medical Segmentation

no code implementations4 Jul 2025 Tao Tang, Shijie Xu, Yiting Wu, Zhixiang Lu

The clinical utility of deep learning models for medical image segmentation is severely constrained by their inability to generalize to unseen domains.

The Panaceas for Improving Low-Rank Decomposition in Communication-Efficient Federated Learning

1 code implementation29 May 2025 Shiwei Li, Xiandi Luo, Haozhao Wang, Xing Tang, Shijie Xu, Weihong Luo, Yuhua Li, Xiuqiang He, Ruixuan Li

To improve the training efficiency of federated learning (FL), previous research has employed low-rank decomposition techniques to reduce communication overhead.

Mixed-Precision Embeddings for Large-Scale Recommendation Models

no code implementations30 Sep 2024 Shiwei Li, Zhuoqi Hu, Xing Tang, Haozhao Wang, Shijie Xu, Weihong Luo, Yuhua Li, Xiuqiang He, Ruixuan Li

Specifically, to reduce the size of the search space, we first group features by frequency and then search precision for each feature group.

Neural refractive index field: Unlocking the Potential of Background-oriented Schlieren Tomography in Volumetric Flow Visualization

no code implementations23 Sep 2024 Yuanzhe He, Yutao Zheng, Shijie Xu, Chang Liu, Di Peng, Yingzheng Liu, Weiwei Cai

Background-oriented Schlieren tomography (BOST) is a prevalent method for visualizing intricate turbulent flows, valued for its ease of implementation and capacity to capture three-dimensional distributions of a multitude of flow parameters.

Masked Random Noise for Communication Efficient Federated Learning

1 code implementation6 Aug 2024 Shiwei Li, Yingyi Cheng, Haozhao Wang, Xing Tang, Shijie Xu, Weihong Luo, Yuhua Li, Dugang Liu, Xiuqiang He, Ruixuan Li

For this purpose, we propose Federated Masked Random Noise (FedMRN), a novel framework that enables clients to learn a 1-bit mask for each model parameter and apply masked random noise (i. e., the Hadamard product of random noise and masks) to represent model updates.

FedBAT: Communication-Efficient Federated Learning via Learnable Binarization

1 code implementation6 Aug 2024 Shiwei Li, Wenchao Xu, Haozhao Wang, Xing Tang, Yining Qi, Shijie Xu, Weihong Luo, Yuhua Li, Xiuqiang He, Ruixuan Li

To this end, we propose Federated Binarization-Aware Training (FedBAT), a novel framework that directly learns binary model updates during the local training process, thus inherently reducing the approximation errors.

Statistically consistent term structures have affine geometry

no code implementations4 Aug 2023 Paul Krühner, Shijie Xu

From a practical perspective, this requires that the chosen set of possible yield curves is compatible with any obtained diffusion coefficient.

Weighted Laplacian and Its Theoretical Applications

no code implementations23 Nov 2019 Shijie Xu, Jiayan Fang, Xiang-Yang Li

In this paper, we develop a novel weighted Laplacian method, which is partially inspired by the theory of graph Laplacian, to study recent popular graph problems, such as multilevel graph partitioning and balanced minimum cut problem, in a more convenient manner.
