In this manuscript, we reinvestigate an existing clustering procedure, optimal discriminant clustering (ODC; Zhang and Dai in Adv Neural Inf Process Syst 23(12):2241–2249, 2009), and propose to use cross-validation to select the tuning parameter. Furthermore, because in high-dimensional data many of the features may be non-informative for clustering, we develop a variation of ODC, sparse optimal discriminant clustering (SODC), by adding a group-lasso type of penalty to ODC. We also demonstrate that both ODC and SDOC can be used as a dimension reduction tool for data visualization in cluster analysis.
