大概是數(shù)學(xué)或是計(jì)算機(jī)方面的,在論文里看到的 一個(gè)是closed-form,一般用來(lái)形容formulation啊,solution啊一類(lèi)的 還有一個(gè)是group lasso,組套索,好像也不大對(duì)啊 期望大牛解答 |

The grouplasso package is a Matlab program that solves the optimization problems of the grouplasso. This code is not meant to be fast but meant to be precise (machine precision duality gap). Moreover, it contains computations of covariance operators in closed form. It is mainly there to allow reproducibility of the results presented in the following paper. http://www.di.ens.fr/~fbach/grouplasso/index.htm |
