* Please make sure you have Java 1.8 * Compile all the java programs in the directory by using the following command: javac *.java * Run FPTree on the given sample.dat file under the sub-directory data as follows: java FPTree data_file min_support ["fp"|"pil"] java FPTree data/sample.dat 2 fp // Runs default fp tree algorithm with descending order f-list java FPTree data/sample.dat 2 pil // Runs pairwise item lift algorithm * You need to provide the filename (along with its path) and the support as arguments. * The programs outputs the following: - The tree size i.e. the number of nodes in the tree - The time required to build it - The average height of the tree - The average branching factor (spread) of the tree - The frequent itemsets along with its support - The statistics of the recursive calls
