A New Method for Performance Analysis in Nonlinear Dimensionality Reduction

16 Nov 2017Jiaxi LiangShojaeddin ChenouriChristopher G. Small

In this paper, we develop a local rank correlation measure which quantifies the performance of dimension reduction methods. The local rank correlation is easily interpretable, and robust against the extreme skewness of nearest neighbor distributions in high dimensions... (read more)
