python -m fp_growth -s {minimum support} {path to CSV file} For example, to find the itemsets with support ≥ 4 in the included example file: python -m fp_growth -s 4 examples/tsk.csv References The following references were used as source descriptions of the algorithm: ...
We compare it with Apriori and FP-Growth. Figure 5.1 shows a set of curves on the scalability with respect to different minimum supports (minsup). These experiments show that TD-FP-Growth is the most efficient algorithm for all data sets and minimum supports tested. Top Down FP-Growth for...
FP-growth algorithm is an algorithm for mining association rules without generating candidate sets. It has high practical value in many fields. However, it is a memory resident algorithm, and can...doi:10.1007/978-981-10-6385-5_15Kuikui Jia...
