Description: 收集数据：使用任何方法
准备数据：任意数据类型都可以，因为我们只保存集合
分析数据：使用任何方法
训练算法：使用Apriori算法来找到频繁项集
测试算法：不需要测试过程
使用算法：用于发现频繁项集以及物品之间的关联规则
使用Apriori算法，首先计算出单个元素的支持度，然后选出单个元素置信度大于我们要求的数值，比如0.5或是0.7等。然后增加单个元素组合的个数，只要组合项的支持度大于我们要求的数值就把它加到我们的频繁项集中，依次递归。
然后根据计算的支持度选出来的频繁项集来生成关联规则。(# Python 3 Implementation of Apriori algorithm
This program is based on [Aaron Zira's implementation of Apriori algorithm](https://github.com/aaronzira/apriori) and is adapted for use in other python 3 programs
## Dependencies
This program uses [_demjson.py_](https://github.com/dmeranda/demjson/blob/master/demjson.py) to write matrix into file
* Install with
```bash
pip3 install demjson
```
## Usage
* Initialize and learn frequency using data from file
```python 3
# data: path of data source file
# out: path of output file
AP = apriori.APriori(data='./test_datasets/transactions.dat',
out='./test_datasets/result.txt')
# This function will write Data into output file
AP.find_frequent(support=50, min_set_size=2, max_set_size=3))

Description: 经典的Apriori算法由于要多次扫描数据库，产生大量的候选项集，极大的影响了算法的时间和空间效率。为了减少数据库的扫描次数，可采用矩阵记录所需数据并放入内存中。矩阵record的每个行号对应一个商品码（即一个项），每个列号对应一个客户号（即一个事务）。倘若第j个客户买了第i个商品，则record[i][j]=1,否则record[i][j]=0. 扫描一遍数据库，将矩阵record初始化。接下来的工作，都可以通过扫描内存中的矩阵进行，不必再扫描数据库。(The classic Apriori algorithm generates many candidate itemsets because it needs to scan the database many times, which greatly affects the time and space efficiency of the algorithm. In order to reduce the number of database scanning, we can use matrix to record the required data and put it into memory. Every row number of matrix record corresponds to a commodity code, that is, one item, and each column number corresponds to a customer number (i.e. a transaction). If a j customer buys a I commodity, then record[i][j]=1, otherwise record[i][j]=0. scan the database once and initialize the matrix record. The next work can be done by scanning the matrix in memory without scanning the database again.)
