大概是数学或是计算机方面的,在论文里看到的
一个是closed-form,一般用来形容formulation啊,solution啊一类的
还有一个是group lasso,组套索,好像也不大对啊
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.
