Group lasso regularization effect for ImageNet

[lizhenstat]

Hi, the paper states that the group lasso term is added to the total cost function, with the coefficient of 1e-5 on ImageNet Dataset. Have you compared the model without group lasso term on the same Dataset? In other words, the group lasso term improves the final validation accuracy by how much percent?

Thanks in advance

Hi there,

I don't have the concrete numbers at hand. But the accuracy on ImageNet is improved by ~0.5% by using the group lasso.

Thanks a lot!
