Overview#
Least Absolute Shrinkage and Selection Operator (
LASSO) is a shrinkage and selection method for
Linear Regression.
Least Absolute Shrinkage and Selection Operator minimizes the usual Residual Sum of Squares (RSS), with a bound on the sum of the absolute values of the coefficients.
Least Absolute Shrinkage and Selection Operator has connections to soft-thresholding of wavelet coefficients, forward stagewise regression, and boosting methods.
Least Absolute Shrinkage and Selection Operator Regularization#
Least Absolute Shrinkage and Selection Operator is used as a
Regularization method to also minimize the absolute sum of the coefficients (called L1
Regularization).
