Exercises
9.1. Provide an example of how people use clustering in their everyday lives. What
are the features that they use to represent the objects? What is the similarity measure?
How do they evaluate the outcome?
9.2. Assume we want to do classification using a very fine-grained ontology, such
as one describing all the families of human languages. Suppose that, before training,
we decide to collapse all of the labels corresponding to Asian languages into a
single “Asian languages” label. Discuss the negative consequences of this decision.
