what does cross validation mean what is the cv which statement best illustrates the independence of independent estimates for cross validation? can you compare the generalization performance of different algorithms cross validation analysis for t test what is the principle behind the t test? what is the independence assumption of the cv which assumption about algorithm independence violate the ttest? what is cross validation why cross validation how does cross validation work why is cross validation necessary why is cross validation necessary? why do we compare the results of a cross validation test cross validation definition which statement best describes the importance of cross validation? when using f1 score does it need to be considered independent what kind of performance does cross validation test why is it important to cross-validate an algorithm? how to compare results of multiple algorithms
