Factorization machine with group lasso
WebIn mathematics, factorization (or factorisation, see English spelling differences) or factoring consists of writing a number or another mathematical object as a product of several … Webrepresented. In this paper we consider extensions of the lasso and LARS for factor selection in equation (1.1), which we call the group lasso and group LARS. We show that these natural extensions improve over the lasso and LARS in terms of factor selection and enjoy superior performance to that of traditional methods for factor selection in ...
