Lasso regularization in a model can described, L1 = (wx + b - y) + a w . w - weight, b - bias, y - label (original), a - alpha constant. If we set 0 value into a, it becomes a linear regression model. Thus for Lasso, alpha should be a > 0. To define the model we use default parameters of Lasso class ( default alpha is 1).
