Há 5 horas · The approach emphasizes meaningful distinctions between classes for the K-Nearest Neighbor (KNN) method. Several distance metrics include Euclidean, City Block, Chebyshev, Minkowski (cubic), Mann-Halanobis, Cosine, Correlation, Spearman, Hamming, and Jaccard. The algorithm is set to consider 10 neighbors for classification.
