Each column of B corresponds to a particular regularization coefficient in Lambda. By default, lasso performs lasso regularization using a geometric sequence of Lambda values. example.

statistics - Can we use LASSO for non-linear regression?

In statistics and machine learning, lasso (least absolute shrinkage and selection operator; also Lasso or LASSO) is a regression analysis method that performs both variable selection and regularization in order to enhance the prediction accuracy and interpretability of the resulting statistical model. It was originally introduced in geophysics, and later by Robert Tibshirani, who coined the term.

Edit: Conducting a OLS-regression seems to be a no-go in this case - I understand the rationale. However, I wonder, how I can assess model quality apart from predictive power in LASSO-setting?

NettetUsing the LASSO for Non-linear Measurements?. The LASSO is by nature tailored to a linear model for the measurements. Indeed, the first term of the objective function in (2) tries to fit Ax to the observed vector y presuming that this is of the form y i= aT i x 0 +noise.
