Web7 Aug 2024 · LASSO is actually an abbreviation for “Least absolute shrinkage and selection operator”, which basically summarizes how Lasso regression works. Lasso does regression analysis using a shrinkage parameter “where data are shrunk to a certain central point” [ 1 ] and performs variable selection by forcing the coefficients of “not-so-significant” variables … Web5 May 2024 · So, the idea of Lasso regression is to optimize the cost function reducing the absolute values of the coefficients. Obviously, this works if the features have been previously scaled, for example using standardization or other scaling techniques. α hyperparameter value must be found using a cross-validation approach.
