Apply the apriori algorithm (Do not forget to specify parameters in your write up). In mathematics, an incidence matrix is a logical matrix that shows the relationship between two classes of objects, usually called an incidence relation. If the first class is X and the second is Y, the matrix has one row for each element of X and one column for each element of Y. The entry in row x and column y is … See more Incidence matrix is a common graph representation in graph theory.
