WebJul 6, 2024 · In this paper, to deal with the problem that nearest neighbor graph is hard to be connected in the original Isomap, a new supervised Isomap method (SS-Isomap) with adaptive parameters is proposed. This method considers the density of intra-class data points and proposes an adaptive function. http://tis.hrbeu.edu.cn/oa/DArticle.aspx?type=view&id=060107
