Benchmarks

• The data format used is the same as in the file test_dataset.txt. That is, different positive integers represent different terms. In addition, "-1" is used as the itemset separator and "-2" is used as the sequence separator. The monetary value and timestamp associated with an item appear within '[]' and '()' respectively.
• Additional datasets used in the paper can be accessed from the branch of datasets.
