association rules in data mining examples
Are there any interesting association rules hidden in our daily data?
This classic example shows that there might be many interesting association rules hidden in our daily data. Association rule mining is a technique to identify underlying relations between different items. There are many methods to perform association rule mining.
What is an example of association rule mining?
A classic example of association rule mining refers to a relationship between diapers and beers. The example, which seems to be fictional, claims that men who go to a store to buy diapers are also likely to buy beer. Data that would point to that might look like this: A supermarket has 200,000 customer transactions.
