K-fold cross-validation with validation and test set

WebThere are two categories of datasets, one of which is additive in nature and does not contain any epistatic effect, and the other category contains both additive and epistatic effects. So, the additive datasets have 10 QTLs, one each in every chromosome, whereas non-additive datasets have one pair of QTLs in 5 of the 10 chromosomes, the rest of the … Web21 mrt. 2024 · The diagram summarises the concept behind K-fold cross-validation with K = 10.
