The owner of a small grocery store wishes to understand their customers better. Specifically, they'd like to segment their customers into a small number of groups with similar purchasing characteristics so as to better target their advertising. They hire you, a data scientist, to do this. So, you do the following: (a) You identify 6 main categories of product: Bread, Fresh fruit & Veggies, Cigarettes, Milk, Canned Food, Newspapers. (b) You select 5 customers and (legally and ethically!) track their purchasing habits for a month. Specifically you record the amount that they spend on each category of product in the month, and then normalize this amount to a number between 0 and 1. This data is presented in matrix X in (8). The first column corresponds to customer 1, the second to customer 2 and so on. The rows corresponds to the product categories, in the order in which they are listed in point (a) above. Also presented in (8) is the non-negative matrix factorization of X. That is, X WH. a X= [0.735 0.179 0.079 0.698 0.307] 0.093 0.655 0.655 0.436 0.604 0.686 0.782 0.547 0.427 0.471 W 0.138 0.223 0.573 0.846 0.164 0.427 0.018 0.488 0.193 0.819 0.78 0.69 0.354 0.221 0.184 [0.162 0.449 0.696] 0.784 0.0 0.0 [0.268 0.557 0.896 0.538 0.854) 0.632 0.599 0.0 H= 0.94 0.595 0.0 0.0 0.0 0.413 0.0 0.648 0.226 0.0 0.0 0.917 0.0 0.62 0.0 0.0 0.336 0.766 0.0 (a) Recall that the columns of W represent the categories, or segments, of customers.
