Web27 mei 2024 · 1) K value is required to be selected manually using the “elbow method”. 2) The presence of outliers would have an adverse impact on the clustering. As a result, outliers must be eliminated before using k-means clustering. 3) Clusters do not cross across; a point may only belong to one cluster at a time.
