留一法交叉验证(Leave-One-Out Cross-Validation,LOO-CV)是贝叶斯模型比较重常见的一种方法。首先,常见的k折交叉验证是非常普遍的一种机器学习方法,即将数据集随机分为k份,其中训练集有(k-1)份,测试集占1份。例如,第一份数据可以用来测试基于剩下(k-1)份数据建立的模型的拟合度,然后将第二份数据作为测试集...

这种方法也被叫做 k k k 折交叉验证法(k-fold cross validation)。最终的结果是这 k 次验证的均值。 此外,还有一种交叉验证方法就是 留一法(Leave-One-Out,简称LOO),顾名思义,就是使 k k k 等于数据集中数据的个数,每次只使用一个作为测试集,剩下的全部作为训练集,这种方法得出的结果与训练整个测试集...
Hold-out cross validation, often considered one of the simplest forms of cross-validation techniques, fundamentally partitions the original dataset into two distinct sets: a training set and a test set. The model is trained using the training set and subsequently evaluated using the unseen test set...

Leave-One-Out Cross-Validation 数据集中有n个样本点时,n折交叉验被称为留一法。 优点是稳定,同一个分类器和数据集用Leave-One-Out计算多次结果是一样的。 缺点是计算开销大。 Definition [1] Leave-one-out cross-validation is a special case of cross-validation where the number of folds equals the...
