Mining various kinds of association rules 4.

In relational database, finding all frequent k-predicate sets will require k or k+1 table scans. Typical Data Mining Architecture 8 6. Enter the email address you signed up with and we'll email you a reset link. that occurs frequently in a data set First proposed by Agrawal, Imielinski, and Swami [AIS93] in the context of frequent itemsets and association rule mining Motivation: Finding inherent regularities in data What products were often purchased together? C 1 L 1 23/82 [ 3] To discover the set of frequent 2-itemsets, L 2, the algorithm uses the join L 1 L 1 to generate a candidate set of 2-itemsets, C2. Based on the kinds of patterns to be mined 15/82 1. If the minimum confidence threshold is, say, 70%, then only the second, third, and last rules above are output, because these are the only ones generated that are strong. Mining various kinds of association rules 4. Mining Association Rules. From association mining to correlation analysis 5. A confidence of 60% means that 60% of the customers who purchased a computer ( ) also bought the software. Data mining should be an interactive process User directs what to be mined using a data mining query language (or a graphical user interface) Constraint-based mining User flexibility: provides constraints on what to be mined System optimization: explores such constraints for efficient mining constraint-based mining 61/82 Constraints in Data Mining Kwledge type constraint: classification, association, etc. This can be done using Equation (5.4) for confidence support count(a B) is the number of transactions containing the itemsets A B support count(a) is the number of transactions containing the itemset A.

Additional analysis can be performed to uncover interesting statistical correlations between associated items. So, what kind of data? [ 2]: Divides the compressed database into a set of conditional databases (a special kind of projected database), each associated with one frequent item or pattern fragment, and mines each such database separately. * multi-relational, A Serial Partitioning Approach to Scaling Graph-Based Knowledge Discovery, Effective Data Retrieval Mechanism Using AML within the Web Based Join Framework, OLAP & DATA MINING CS561-SPRING 2012 WPI, MOHAMED ELTABAKH, Review.

The name of the algorithm is based on the fact that the algorithm uses prior kwledge of frequent itemset properties Concept: 1. The pattern growth is achieved by the concatenation( ) of the suffix pattern with the frequent patterns generated from a conditional FP-tree. An itemset that contains k items is a k-itemset.
