What is the main issue with the k-means algorithm when dealing with outliers?
What is the main issue with the k-means algorithm when dealing with outliers?
An object with an extremely large value may substantially distort the distribution of the data.
What is the main difference between the k-means algorithm and the k-medoids algorithm?
What is the main difference between the k-means algorithm and the k-medoids algorithm?
The k-means algorithm uses the mean value of the objects in a cluster as a reference point, whereas the k-medoids algorithm uses the most centrally located object (medoid) in a cluster.
