Stable Density Ridges: Consistency and Convergence of Subspace Constrained Mean Shift
By Wanli Qiao · Paper · stat.ML
The Subspace Constrained Mean Shift (SCMS) algorithm is a popular nonparametric method for extracting density ridges, which serve as a low-dimensional representation of high-dimensional data. It is a widely held belief in the literature that SCMS trajectories converge to the clas
