How knn works

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 ... Web22 aug. 2024 · Hi, KNN works well for dataset with less number of features and fails to perform well has the number of inputs increase. Certainly other algorithms would show a better performance in that case. With this article I have tried to introduce the algorithm and explain how it actually works (instead of simply using it as a black box). Reply
