How does KNN work if there are duplicates? - Data Science Stack Exchange
WebThis would not be the case if you removed duplicates. Suppose that your input space only has two possible values - 1 and 2, and all points "1" belong to the positive class while points "2" - to the negative. If you remove duplicates in the KNN (2) algorithm, you would always end up with both possible input values as the nearest neighbors of any ...
