When trying to use knn, I get a error message like below,
## 錯誤在knn(train.data, validation.data, cl, use.all = FALSE) :
## too many ties in knn
## try using test data to see if that is because training data has
## too many similar instances
where "train.data" is my training data and "validation.data" is the data I
used for validation.
My question is, does that means there are too many similar instances
in training instances?
Did anyone ever get into this problem?
Any suggestion would be appreciated.
Thanks.
