I wonder, if coefficients can be larger than 1 even on the normalized data ?
I am bench making liblinear with glmnet, and I see one of the coefficients is larger than one.

Thanks.

Do you mean the weight vector? If so, yes they can be larger than 1

Thanks for your answer. I have another issue, the glmnet solution is sparser than LIBLINEAR solution - I wonder if there could be any explanation ? :-) - thanks.

If the same loss and the same parameters are used, I think they should
give the same sparsity
