Centroid meaning
WebA centroid is a vector that contains one number for each variable, where each number is the mean of a variable for the observations in that cluster. The centroid can be thought … WebAug 24, 2024 · Additionally, harmonic mean distance focuses on more consistent local centroid mean vectors in classification decision; this makes it less sensitive to neighborhood size k. The rationale behind the proposed (LMKHNCN), which is a new version of KNN classifier, is described below.
