WebMay 5, 2024 · aj is the coefficient of the j-th feature.The final term is called l1 penalty and α is a hyperparameter that tunes the intensity of this penalty term. The higher the coefficient of a feature, the higher the value of the cost function. So, the idea of Lasso regression is to optimize the cost function reducing the absolute values of the coefficients. flea \u0026 tick treatments in orange park
