PCY implementation

Example

test.py

from pcy_algo import pcy_algo
num_transactions = pd.read_csv("path/to/dataset")
hash_func_size = 40 
support = 500 # 5 percentage
confidence = 30

num_transactions containes baskets with items encoded as integers

• num_transactions = [[12,1,2,3,4],[2,3,49,45,12],[12,98,45,22]]

unique_items contains distinct elements.

• unique_items = (12,1,2,3,4,49,45,98,22)

create object

basket = pcy_algo(num_transactions,unique_items,hash_func_size,support,confidence)
result = basket.mine_data()
