针对语义分割模型识别碳滑板边缘困难、复杂背景干扰性较大以及特征信息丢失严重等问题,提出一种新型编解码结构的Swin Transformer语义分割优化算法。首先,主干网络采用U型的编解码结构,实现多尺度的信息融合;其次,添加注意力局部增强感知模块来扩大感受野并提高模型泛化能力;然后,采用具有数据相关性的上采样结构,以提高上采样质量,摆脱分辨率对预测结果的影响,加强图像重建能力;最后,将跳跃连接更换为残差路径,使编解码结构中的语义信息联系更加紧密,提升训练效率。实验结果表明,Swin Transformer语义分割优化算法相较基线算法测量预测精度提高了3.63.,所有类别中的像素分类正确率的平均值提高了7.29%。研究结果综合验证了新型编解码结构的Swin Transformer语义分割模型在识别和处理碳滑板任务中的优越性及鲁棒性。

Wuhan university Journal of Natural sciences 2008年第4期13卷 396-400页

作者： zheng Liang LI Xueming College of computer science Chongqing UniversityChongqing 400044 China

In order to realize the intelligent management of data mining （DM） domain knowledge, this paper presents an architecture for DM knowledge management based on ontology. Using ontology database, this architecture can realize intelligent knowledge retrieval and automatic accomplishment of DM tasks by means of ontology services. Its key features include：①Describing DM ontology and meta-data using ontology based on Web ontology language （OWL）.② Ontology reasoning function. Based on the existing concepts and relations, the hidden knowledge in ontology can be obtained using the reasoning engine. This paper mainly focuses on the construction of DM ontology and the reasoning of DM ontology based on OWL DL（s）.

Protocol translation is required for IPv4/IPv6 multicast communication. The Multicast Transition Gateway (MTG) technology is a good solution for the realization of IPv4/IPv6 multicast interoperability. With this technology,the MTG is deployed at the edges of IPv4 and IPv6. The IPv4 and IPv6 networks are considered as peer-to-peer heterogeneous networks. The IPv6 multicast source can be added to the IPv4 multicast group and the IPv4 multicast source can also be added to the IPv6 multicast group. In the IPv4 network,MTG acts as an agent of IPv6 participate in IPv4 multicast,and vise a versa. Within the MTG system,the two agents translate protocols.
