该文主要从3个方面介绍李群机器学习近年来的研究进展.首先,该文将解释为什么采用李群结构进行数据或特征描述,以此阐明李群机器学习与传统机器学习方法的区别,并且通过李群在人工智能领域的广泛应用来说明李群表示的普遍性.其次,该文概述了李群机器学习自提出以来的主要学习算法,着重强调最近的一些研究进展.最后,针对目前的研究现状,该文给出李群机器学习未来的一些研究方向.
This paper introduces advances in the study of Lie group machine learning(LML)from three aspects.First,this paper presents the reasons why we choose Lie group to describe features,aiming at clarifying the differences between LML and traditional machine learning methods.By showing extensive applications in artificial intelligence area,we illustrate the universality of Lie Group representation.Second,this paper outlines the main LML algorithms since proposed,with an emphasis on recent research progress.At last,according to the current development,this paper shows some future research directions about LML.
