Which of the following actions is NOT a step to kmeans clustering? 0 Selecting the number of clusters 0 Measure distance of other points from point k 0 Calculate the average of each cluster C.) Assign each point to a distant centroid Which of the following is NOT true in regards to the \"Ir-means\" clustering? O "k\" is chosen before the process begins 0 "means" denotes the average of the values along each dimension (feature) for the instances in the cluster Q Is different than the Hierarchical Clustering O Implemented using a simple 3-step algorithm In this dendrogram, which two points/clusters are clustered at first? 0.25 0.20 -.---. 2 clusters 0.15 To------- 3 clusters Distance 0.10 ....... 4 clusters 0.05 ............... 5 clusters 0.0 A B E D F Cluster O ACBED and F O D and F O B and E O None of aboveIn the k-nearest neighbor method, what should be the proper value of k? 0 k = 1 k = maximum number of instances 0 1 >= k >= Maximum Instances Q 1
