WebApr 21, 2024 · K is a crucial parameter in the KNN algorithm. Some suggestions for choosing K Value are: 1. Using error curves: The figure below shows error curves for different values of K for training and test data. Choosing a value for K At low K values, there is overfitting of data/high variance. Therefore test error is high and train error is low.
