Webb但是它们有一个不同之处，就是第一个代码中的lr没有指定正则化项的类型和强度，而第二个代码中的lr指定了正则化项的类型为l2正则化，强度为0.5。这意味着第二个代码中的逻辑回归模型在训练过程中会对模型参数进行l2正则化，以避免过拟合。 Webb31 juli 2024 · L2 Regularization or Ridge L2 Regularization technique is also known as Ridge. In this, the penalty term added to the cost function is the summation of the squared value of coefficients. Unlike the LASSO term, the Ridge term uses squared values of the coefficient and can reduce the coefficient value near to 0 but not exactly 0.
