中文摘要：

高维数据可视化分析是数据分析与可视化领域的研究热点,传统的降维方法得到的低维空间往往难以解释,不利于人们对高维数据的可视化分析与探索。提出一种新的可视化解释器（Explainer）方法,将L1稀疏正则化特征选取引入到高维数据的可视化处理过程中,建立起高层语义标签与少量的关键特征之间的联系。通过可视化设计与实验验证了该方法可以有效改善高维数据的可视化分析性能。

英文摘要：

High-dimensional data visualization analysis is the research hotspot in the field of data analysis andvisualization, the traditional low-dimensional dimension reduction method is often difficult to explain, and is not conducive to the visualization of high-dimensional data analysis and exploration. In this paper, a new visual explorer （Explainer） method is proposed to introduce the LI sparse regularization feature selection into the high-dimensional data visualization process, and establish the relationship between high-level semantic tags and a few key features. The feasibility of the method is verified by visual design and experiment. It can improve the visualization performance of high dimensional data effectively.
