Using 20% as our tolerance threshold again, the following plot shows what an overestimated workload looks like: If we end up in this situation we should "drill-down" into our metrics data and identify the pods that contribute the most to the overestimation. We should, then, have a ...
You can plot points on a two-dimensional graph, as shown in the graphs below. On the left, we have a random distribution of the 30 points. The first iteration of the k-means clustering divides the points into five groups, with each cluster represented by a different color, as shown in...
Therefore a good clustering should have mostly high numbers for each cluster in its silhouette plot. We can see from these plots that for both 2 and 3 clusters, there is good separation between the clusters (i.e., large distances to neighboring clusters), but for 4 clusters, we have some...

The bottom part of the plot represents the starting point of the analysis, where there are as many clusters as individuals (the abscissa does not have a numerical scale and just accommodates object indices arranged so as to provide the best readability of the figure). As the agglomeration proc...
The chapter includes discussion of the following topics: definitions (hard clustering, crisp clustering, fuzzy clustering, descriptive clustering, and synoptic clustering), basic model (single linkage clustering, link, dendrogram, edge, node, undirected graph, chain, chaining, connected subgraph, minimum...
