[BioC] KNN, SVM, and randomForest - How to predict samples without category

[Tom R. Fahland]

By definition, in supervised learning you always train (with known
catagories), then run your unbiased data through for prediction. Both CV
and train/test partitions are good for choosing parameters and
optimizing the algorithms. I have just completed a study predicting dose
expsoure with good reasults using different algorithms.

Dear all,

Supervised clusterings (KNN, SVM, and randomForest) use test sample set
and train sample set to do prediction. To create the expreSet, the
category is needed for each sample. However sometimes we need to predict
sample without its category. Anybody has some clue to do this? Thank you
very much!

Best regards,
Xin LIU
