LDA is particularly useful for finding reasonably accurate mixtures of topics within a given document set. It is often used by grocery stores, retailers, and anyone with a large transactional databases. The Problem. Intuitively, you might think that data “mining” refers to the extraction of new data, but this isn’t the case; instead, data mining is about extrapolating patterns and new knowledge from the data you’ve already collected. You should contact the package authors for that. Then Getting in to Machine Learning. Association Rules & Frequent Itemsets All you ever wanted to know about diapers, beers and their correlation! Data Mining: Association Rules 2 The Market-Basket Problem • Given a database of transactions, find rules that will predict the occurrence of an item based on the occurrences of other items in the transaction Market-Basket transactions. Apriori algorithm (Agrawal & Srikant 94) Idea: use one-item sets to generate two-item sets, two-item sets to generate three-item sets, … If (A B) is a frequent item set, then (A) and (B) have to be frequent item sets as well! In general: if X is frequent k-item set, then all (k-1)-item subsets of X are also frequent. It avoids academic language and takes you straight to the techniques you'll use in your day-to-day work.

LDA is particularly useful for finding reasonably accurate mixtures of topics within a given document set. It is often used by grocery stores, retailers, and anyone with a large transactional databases. The Problem. Intuitively, you might think that data “mining” refers to the extraction of new data, but this isn’t the case; instead, data mining is about extrapolating patterns and new knowledge from the data you’ve already collected. You should contact the package authors for that. Then Getting in to Machine Learning. Association Rules & Frequent Itemsets All you ever wanted to know about diapers, beers and their correlation! Data Mining: Association Rules 2 The Market-Basket Problem • Given a database of transactions, find rules that will predict the occurrence of an item based on the occurrences of other items in the transaction Market-Basket transactions. Apriori algorithm (Agrawal & Srikant 94) Idea: use one-item sets to generate two-item sets, two-item sets to generate three-item sets, … If (A B) is a frequent item set, then (A) and (B) have to be frequent item sets as well! In general: if X is frequent k-item set, then all (k-1)-item subsets of X are also frequent. It avoids academic language and takes you straight to the techniques you'll use in your day-to-day work.
