Web2 Pairwise Fused Lasso (PFL) The original fused lasso (Tibshirani et al., 2005) was developed for ordered pre-dictors or signals as predictors and metrical response. For … WebThe clustered Lasso model has been applied in microarray data analysis. In ad-dition, the clustered Lasso can be used as a pre-processing step for the fused Lasso or the group Lasso for uncovering the group structure of the predictors. Researchers have designed some algorithms for solving (1.1) through reformulating (1.1) as a con-
