WebThe K-means method is sensitive to anomalous data points and outliers. If you have an outlier then whatever cluster it would be included in, the centroid of that cluster would be pulled out to towards that point. The K-mediod method is robust to outliers when robust distance measures such as Manhattan distance are used. WebOct 4, 2024 · K-means clustering algorithm works in three steps. Let’s see what are these three steps. Select the k values. Initialize the centroids. Select the group and find the …
