# Apriori-FP-Growth

数据挖掘常用算法对比测试

## Usage

```
git clone git@github.com:JackHCC/Apriori-and-FP_Growth.git
cd Apriori-and-FP_Growth
```

- Apriori

```
python Apriori.py
```

- FP-Growth

```
python FP_Growth.py
```

## DataSet设置

```python
data_set = [
        ['牛奶', '鸡蛋', '面包', '薯片'],
        ['鸡蛋', '爆米花', '薯片', '啤酒'],
        ['牛奶', '啤酒', '面包'],
        ['牛奶', '鸡蛋', '面包', '爆米花', '啤酒', '薯片'],
        ['鸡蛋', '面包', '薯片'],
        ['鸡蛋', '面包', '啤酒', ],
        ['牛奶', '面包', '薯片'],
        ['牛奶', '鸡蛋', '面包', '黄油', '薯片'],
        ['牛奶', '鸡蛋', '黄油', '薯片']
    ]
```
