Apriori [1] is an algorithm for frequent item set mining and association rule learning over relational databases. It proceeds by identifying the frequent individual items in the database and extending them to larger and larger item sets as long as those item sets appear sufficiently often in the database.
For the most part, FP discovery can be done using association rule learning with particular algorithms Eclat, FP-growth and the Apriori algorithm. Other strategies include: Frequent subtree mining; Structure mining; Sequential pattern mining; and respective specific techniques.
Sequential pattern mining is a topic of data mining concerned with finding statistically relevant patterns between data examples where the values are delivered in a sequence. [ 1 ] [ 2 ] It is usually presumed that the values are discrete, and thus time series mining is closely related, but usually considered a different activity.

As the Jewish Festival of Lights, or Hanukkah, is fast approaching (December 25, 2024 to January 2, 2025), we’re looking forward to playing dreidel (and winning gelt!), lighting the menorah with ...
For example a 10^4 frequent 1-itemset will generate a 10^7 candidate 2-itemset. The algorithm also needs to frequently scan the database, to be specific n+1 scans where n is the length of the longest pattern. Apriori is slower than the Eclat algorithm. However, Apriori performs well compared to Eclat when the dataset is large.

Some hospitals in the U.S. are seeing an increase in RSV and higher levels of "walking pneumonia" among young children despite overall respiratory illness activity remaining low nationally.
