五折交叉验证(5-fold cross-validation)是一种评估模型性能的技术。 给定条件和符号定义 数据集: (Xk,Yk) ,其中: Xk∈Rnk×p :第 k 个数据集的特征矩阵,包含 nk 个样本和 p 个特征。 Yk∈Rnk×1 :第 k 个数据集的响应向量。 数据集总数:m 正则化参数集合: Λ1={λ1,1,λ1,2,…,λ1,q} Λ...
五折交叉验证是评估模型性能的技巧。初始化步骤:遍历参数组合。执行五折交叉验证:将数据集分为五个相等的子集。每次训练时,将一个子集作为验证集,其余作为训练集。模型训练后,计算该次验证集上的测试误差。利用`magnitude_joint`函数进行幅度收缩的回归分析。重复此过程五次,每次使用一个不同子集作为验...
Cross-Validation & Nested Cross-Validation 验证用于选择超参数。最后,基于选出的超参数和全部数据集,产生最终的模型。 尽管这样,还是有可能在模型选择阶段存在过拟合(NestedCross-Validation只是允许你可以对这种情况进行测试,如何测?)。一种解决方法是在cross-validationerror中加入正则项,用于惩罚易产生过度复杂模型的...
