K-fold cross-validation will be done K times. In each stage, one fold gets to play the role of validation set whereas the other remaining parts (K-1) are the training set. For each stage, cross-validation invo

X``y This is my first time using KFold Cross Validation because my model score overifts and i thought i could fix it with cross validation. I'm still confused of how to use this, i have read the documentation and some articles but i do not really catch how do i really imply it to...
Using the K-Fold Cross-Validation Statistics to Understand the Predictive Power of your Data in SVS In cross-validation, a set of data is divided into two parts, the “training set” and the “validation set”. A model for predicting a phenotype from genotypic data and (usually)...
cv: int, cross-validation generator or an iterable, optional Determines the cross-validation splitting strategy. Possible inputs for cv are: - None, to use the default 3-fold cross validation, - integer, to specify the number of folds in a `(Stratified)KFold`, ...

cv:代表的就是不同的cross validation的方法了。引用scikit-learn上的一句话(When the cv argument is an integer, cross_val_score uses the KFold or StratifiedKFold strategies by default, the latter being used if the estimator derives from ClassifierMixin.)如果cv是一个int数字的话,那么默认使用的是K...
