When is Network Lasso Accurate: The Vector Case

no code implementations11 Oct 2017 Nguyen Tran, Saeed Basirian, Alexander Jung

A recently proposed learning algorithm for massive network-structured data sets (big data over networks) is the network Lasso (nLasso), which extends the well- known Lasso estimator from sparse models to network-structured datasets.
