Dear Editor,This letter proposes a parameter-free multiple kernel clustering(MKC)method by using shifted laplacian *** MKC can effectively cluster nonlinear data,but it faces two main challenges:1)As an unsupervised method,it is up against parameter problems which makes the parameters intractable to tune and is unfeasible in real-life applications;2)Only considers the clustering information,but ignores the interference of noise within laplacian.
