"WebLasso regression is, like ridge regression, a shrinkage method. It differs from ridge regression in its choice of penalty: lasso imposes an ℓ 1 penalty on the parameters β. That is, lasso finds an assignment to β that minimizes the function. where λ is a hyperparameter and, as usual, X is the training data and Y the observations. " - Cvxpy random seed
