    A survey of deep learning-based MRI stroke lesion segmentation methods by Weiyi YU, Tao CHEN, Junping ZHANG, Hongming SHAN

    Published 2023-09-01
    “…Automatic stroke lesion segmentation has become a research hotspot in recent years.In order to comprehensively review current progress of deep learning-based MRI stroke lesion segmentation methods, start with the clinical problems of stroke treatment, we further elaborate the research background and challenges of deep learning-based lesion segmentation, and introduce common public datasets (ISLES and ATLAS) for stroke lesion segmentation.Then, we focus on the innovation and progress of deep learning-based stroke lesion segmentation methods, and summarize the research progress from three perspectives: network structure, training strategy, and loss function, and compare the advantages and disadvantages of various methods.Finally, we discusse the difficulties and challenges in this research and its future development trend.…”

    基于MATLAB与VRML的凸轮机构虚拟设计研究及实现 by 张明, 周智峰

    Published 2006-01-01
    “…Integrating Matlab Virtual Reality Toolbox,Matlab language and VRML technology,a virtual design system has been developed,on which various cam mechanisms can be designed.The software has a simple and clear graphical user interfaces,and can provide user with parameterized design,three-dimensional graphics and virtual simulation.Further more,the software has some assistant function such as parameter optimization,movement performance analysis,output for graphics and character data,and so on.On this system,user can interact on the virtual scene of cam mechanism created Real-timely,and control the course of simulation.The system indicates that the method can effectively reduce the difficulties and workload,and shorten the time of programing accordingly,because it could take advantage of MATLAB’s and VRML’s strongpoints.…”

    High-dimensional outlier detection based on deep belief network and linear one-class SVM by Haoqi LI, Na YING, Chunsheng GUO, Jinhua WANG

    Published 2018-01-01
    “…Aiming at the difficulties in high-dimensional outlier detection at present,an algorithm of high-dimensional outlier detection based on deep belief network and linear one-class SVM was proposed.The algorithm firstly used the deep belief network which had a good performance in the feature extraction to realize the dimensionality reduction of high-dimensional data,and then the outlier detection was achieved based on a one-class SVM with the linear kernel function.High-dimensional data sets in UCI machine learning repository were selected to experiment,result shows that the algorithm has obvious advantages in detection accuracy and computational complexity.Compared with the PCA-SVDD algorithm,the detection accuracy is improved by 4.65%.Compared with the automatic encoder algorithm,its training time and testing time decrease significantly.…”
