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. WebK-means is an unsupervised learning method for clustering data points. The algorithm iteratively divides data points into K clusters by minimizing the variance in each cluster. …
