Python Implementation of Apriori Algorithm for finding Frequent sets and Association Rules

Python Implementation of Apriori Algorithm

The code attempts to implement the following paper:

Agrawal, Rakesh, and Ramakrishnan Srikant. "Fast algorithms for mining association rules." Proc. 20th int. conf. very large data bases, VLDB. Vol. 1215. 1994.

List of files

1. apriori.py
2. INTEGRATED-DATASET.csv
3. README(this file)

The dataset is a copy of the “Online directory of certified businesses with a detailed profile” file from the Small Business Services (SBS) dataset in the NYC Open Data Sets <http://nycopendata.socrata.com/>_

Usage

To run the program with dataset provided and default values for minSupport = 0.15 and minConfidence = 0.6

python apriori.py -f INTEGRATED-DATASET.csv

To run program with dataset

python apriori.py -f INTEGRATED-DATASET.csv -s 0.17 -c 0.68

Best results are obtained for the following values of support and confidence:

Support : Between 0.1 and 0.2

Confidence : Between 0.5 and 0.7
