Question



taking Y of the nearest neighbors

Professor,

How do you manually take Y of the nearest neighbors?

I see in the textbook that the training set has a dependent variable y = {0,1} but I am unsure of how to apply this to my 5 least
dissimilar instances.

Thanks

Dear student,

If you know the row indices of the nearest neighbors, you can simply use subsetting to retrieve the labels ,as in:

Y[ind]

where Y are the labels and ind are the indices.
