LASSO回归(Least Absolute Shrinkage and Selection Operator Regression)是一种线性回归的扩展,通过引入L1正则化项来约束模型的复杂度,从而实现特征选择和减少过拟合。以下是LASSO回归的原理和步骤: 原理 L1正则化:LASSO回归在标准的线性回归损失函数中加入了L1正则化项,即对模型系数的绝对值求和进行惩罚。这种正则化方式...

regression modelsSummary The computation of least absolute shrinkage and selection operator (LASSO) estimate involves the solution of a quadratic programming problem with linear inequality constraints. LASSO can be thought of as a penalty-based variable selection approach that selects variables to be ...
Thus, the least absolute shrinkage and selection operator (LASSO) technique, which is a penalized regression method, is presented as another alternative for predictor selection in downscaling GCM data. It may allow for more accurate and clear models that can properly deal with collinearity problems....
