rustyfim 0.2.2

No project description provided

rustyfim enables you to run frequent itemset mining algorithm (both FPGrowth that mines frequent itemset, and DCI algorithm that mines closed item sets) in Python

Setup

pip install maturin
maturin develop

Running FIM in python

from rustyfim import fpgrowth, dci

res = fpgrowth(min_support=0.3, transactions=[[1,2,3],[2,3,4],[3,4,10],[3,4,20]])
# in dci algorithm, n_features is required for creating the bitmatrix in the first place
res = dci(min_support=0.3, transactions=[[1,2,3],[2,3,4],[3,4,10],[3,4,20]], n_features=21)

Result:

First pass took 0 ms, num_transactions=4.
Total runtime: 1 ms
[([3], 4), ([3, 4], 3), ([4], 3)]
