Consider a dataset of 4 objects: {O1,O2,O3,O4}. The following tables show their pairwise distances, which are based on a set of attributes. Using the information provided in the table, compute the silhouette coefficient for each object. a) Calculate BCubed Precision and Recall for each object, and then for the whole clustering result. Add your results in the following table. Round your numbers to 2 decimal places
