Question: Clustering, Linear Independence. a) Suppose you are trying to understand the movie preferences of the students in a class. You conduct a survey, asking students to rank their enjoyment of the following genres, on a scale of 0-1: 'Historical Drama','Sci-Fi', 'Comedy', 'Action'. Using at most 3 sentences, explain how you would set up your survey data in the form of vectors, so that you could then use clustering to learn whether there are distinct groups of movie preferences within the class.

b) Building on the above scenario, provide a small modification to the k-means method that uses angle instead of Euclidean distance within the clustering objective.

c) Discuss the relative merits of using angle vs. Euclidean distance for the above movie scenario.
