Suppose you are the manager of a supermarket, you will want to understand the customer's shopping habits. You'll want to know what customers might buy at one time in the shopping, so you can arrange the shelves to make a bigger profit. This is the Association Rules (Association Rule). Its manifestations are as follows:bread⇒milk[support=10%;confidence=60%] Bread\

suggest might be associated with other properties in the dataset? If you know that there is an association between them, what will help? In addition to the properties in the example, it is considered that the average indoor time for family members is also related to the demand for hot fuel. The average indoor time of a family member directly affects the time to maintain the room temperature and the consumption of hot fuel, and the greater the demand

### AssociationRules 1

Association Rules? Item and item set The smallest unit information that is indivisible in a database is called an item (or item), represented by a symbol, and a collection of items is called an item set. Set is the set of items, the number of items in the collection is called-itemsets. For example, the collection {beer, diaper, milk powder} is a 3-item set. Transaction A set is a

### Frequent itemsets and Associationrules (English version)

### Data Mining Series (3) Evaluation of associationRules

The Association rules we discussed earlier are evaluated with support and confidence, and if a rule has a high level of self-confidence, we say it is a strong rule, but self reliability and support can sometimes not measure the actual meaning of the rule and the interest point of the business concern. A strong rule that misled us. Looking at an example, we analyze the relationship between buying a game di
