soda} rule has the highest confidence at 20%. For example, if we consider the rule {1, 4} ==> {2, 5}, it has a lift … In other words, the Lift Ratio is the Confidence divided by the value for Support for C. For Rule 2, with a confidence of 90.35%, support is calculated as 846/2000 = .423. Now give a quick look at the rules. a. In practice, a rule needs the support of several hundred transactions, before it can be considered statistically significant, and datasets often contain thousands or millions of transactions. Association rule mining finds interesting associations and correlation relationships among large sets of data items. A typical example of association rule mining is Market Basket Analysis. How many of those transactions support the consequent if the lift ratio is 1.875? The interestingness of an association rule is commonly characterised by functions called ‘support’, ‘confidence’ and ‘lift’. The association rule mining task can be defined as follows: Let I = { i 1 , i 2 , …, i n } be a set of n binary attributes called items . Association rules show attribute value conditions that occur frequently together in a given data set. a. lift b. antecedent REVIEWER IN BUSINESS ANALYTICS Page 6 The higher the value, the more likely the head items occur in a group if it is known that all body items are contained in that group. For an association rule X ==> Y, if the lift is equal to 1, it means that X and Y are independent. the confidence of the association rule is 40%. The larger the lift ratio, the more significant the association." lift of association rule {(a, b)} -> {(c)}: 40 / ((5.000 / 100.000) * 100) = 8.. the lift is the ratio of the confidence to the expected confidence of an association rule.
