[PDF] association analysis example

In association analysis, a collection of zero or more items is termed an itemset. If an itemset contains k items, it is called a k-itemset. For instance, {Beer, Diapers, Milk} is an example of a 3-itemset. The null (or empty) set is an itemset that does not contain any items.

  • What is an example of association analysis in data mining?

    Association Rule
    Let I1 & I2 be 2 disjoint item-sets. If I1 & I2 are associated, then, I1 ?I2. Ex: If I1={Beer} & I2={Diaper, Eggs} & if they are associated, then, {Beer} ?{Diaper, Eggs}.

  • What is an association analysis?

    Association analysis is the task of finding interesting relationships in large datasets. These interesting relationships can take two forms: frequent item sets or association rules.

  • What is an example of an association model?

    Association models allow you to predict which items are most likely to appear together, and predict the strength of the relationship between them. states that beer often occurs when cannedveg and frozenmeal occur together. The rule is 84% reliable and applies to 17% of the data, or 173 records.
  • Association rule mining could be used to identify relationships between items that are frequently purchased together. For example, the rule "If a customer buys bread, they are also likely to buy milk" is an association rule that could be mined from this data set.
