cvtype.image | R Documentation |
This function generates test dataset index of two-dimensional data for cross-validation
cvtype.image(n, cv.bsize=c(1,1), cv.kfold)
n |
the size of image |
cv.bsize |
two-dimensional block size of cross-validation |
cv.kfold |
the number of fold of cross-validation |
This function provides indexes of two-dimensional cross-validation scheme. Only random cross-validation scheme is provided.
Two matrix representing test dataset index of each dimension for cross-validation.
cv.index1 |
each row is test dataset index of one dimension |
cv.index2 |
each row is test dataset index of the other dimension |
