标 题: 求助: about leave-one-out cross validation
发信站: BBS 未名空间站 (Thu Feb 21 10:34:05 2008)
I am using LOOCV to estimate the classification accuracy because of small
sample size.
There are 3 classes. The sample size of these classes are [ 10 12 15]. I
used LOOCV on 10+12+15=37 samples.
My question is will the unbalanced sample size affect the estimation of
classifcation accuracy. Do I need to change the prior possiblity in the
classifier?
谢谢大牛们指点
