some question on KNN

[loovi7]

As is said in the work, it is unsupervised.but the labels of train data are used when KNN evaluation.So it's OK to do like this?

The word 'unsupervised' refers to the method of training neural network models and learning useful representations. While the KNN evaluation requires training data, it is quite simple without even adding extra weights like what people usually do with linear evaluation (i.e., fix the network and add one linear layer for classification).
