"WebApr 7, 2024 · Weighted K-NN. Weighted kNN is a modified version of k nearest neighbors. One of the many issues that affect the performance of the kNN algorithm is the choice of the hyperparameter k. If k is too small, the algorithm would be more sensitive to outliers. If k is too large, then the neighborhood may include too many points from other classes. " - Neighbor python
