... For our example, we will use the familiar katydid/grasshopper dataset. However, in this case we are imagining that we do NOT know the class labels. We are only clustering on the X and Y axis values. ...

... parameters; in particular how you’ve chosen the values K1, K2 for k-means. Plot figures by using different colors or different markers to show what cluster each data point belongs. Explain the differences of the two datasets based on the results of the clustering. Finally, give a suggestion how a k- ...

A partitioning method creates an initial set of number of partitions, where parameter k is the number of partitions to construct; then it uses an iterative relocation technique that attempts to improve the partitioning by moving objects from one group to another. Typical partitioning methods include ...
