为了将高维输入空间的数据映射到低维空间,利用可视化技术探测数据的固有特性,提出了用非线性主成分分析(NLPCA:NonLinear Principal Component Analysis)和自组织映射网络相结合的方法对生物信息学中基因表达数据进行聚类可视化分析。...为了将高维输入空间的数据映射到低维空间,利用可视化技术探测数据的固有特性,提出了用非线性主成分分析(NLPCA:NonLinear Principal Component Analysis)和自组织映射网络相结合的方法对生物信息学中基因表达数据进行聚类可视化分析。实验结果表明,该方法有较高的分类正确率,用于基因表达数据的聚类分析是行之有效的。展开更多
目的用科学知识图谱方法对神经保护剂在脑卒中领域的相关文献作系统梳理,准确清晰地展现该领域的知识结构、研究方向和研究热点。方法基于Web of Science(核心合集)数据库,检索2005年至2018年的脑卒中-神经保护剂研究领域的文献,用Cites...目的用科学知识图谱方法对神经保护剂在脑卒中领域的相关文献作系统梳理,准确清晰地展现该领域的知识结构、研究方向和研究热点。方法基于Web of Science(核心合集)数据库,检索2005年至2018年的脑卒中-神经保护剂研究领域的文献,用CitespaceⅢ软件和WOS数据库自带的文献统计工具对脑卒中-神经保护剂研究领域的相关文献进行梳理统计及知识图谱可视化分析,用VOS viewer软件进行聚类分析。结果本研究共纳入1995篇文献。全球对于脑卒中-神经保护剂的研究总体呈缓慢上升趋势;高被引文献主要分为3个聚类,分别集中于对脑卒中及缺血性脑损伤的病生理机制的研究、对急性缺血性脑卒中的临床治疗和对新型神经保护剂自由基清除剂NXY-059的相关研究。结论截止到目前,神经保护剂仍有较大的发展空间,针对细胞凋亡、氧化应激和炎症反应等病生理机制是目前神经保护剂发展的方向。展开更多
