WebSep 1, 2024 · KNN is a supervised learning algorithm, based on feature similarity. Unlike most algorithms, KNN is a non-parametric model which means it does not make any assumptions about the data set. This makes the algorithm simpler and effective since it can handle realistic data. WebSep 5, 2024 · As we saw above, KNN can be used for both classification and regression problems. The algorithm uses ‘ feature similarity ’ to predict values of any new data points. This means that the new point is assigned a value based on how closely it resembles the points in the training set.
