A Novel Convex Clustering Method for High-Dimensional Data Using Semiproximal ADMM
Clustering is an important ingredient of unsupervised learning; classical clustering methods include K-means clustering and hierarchical clustering. These methods may suffer from instability because of their tendency prone to sink into the local optimal solutions of the nonconvex optimization model....
