Generalized Lasso Regularization for Regression Models

WebFused lasso penalty, which imposes sparse penalties not only on individual networks but also on the differences between each pair of networks, has been proven to be effective on joint estimation of multiple networks (Danaher et al., 2014). However, traditional fused lasso penalty does not take into account prior information.
