Hi,
In mentioned question on Accuracy is not the evaluating matrices for association rules.
Support, Confidence and Lift are the evaluating matrices for association rules.
Association rule is mainly used for finding patterns ,
co-occurrence in the database.
It works on the basis of if-then associations.
Mainly three metrics are used to evaluate an associate rule:
Support : It denotes that how frequently the
particular item occurs in the data.
Confidence : It denotes that number of items in
such a way that how many if-then statements are true in respect of
that item.
Lift: It is used to compare the current confidence
with expected confidence.
Note : If you have any further query, please
feel free to ask, just drop a comment in comment box. I would be
very happy to resolve all your queries.
Thank You !

Which of the following statements about lift are false? Check all that apply. Correct answers will increase your score. Incorrect answers will decrease our score. Lift and drag forces are always perpendicular Wing shape is not important for generating lift. Surface roughness doesn't impact the lift force generated by rotating/spinning objects. The area used in the definition of the lift coefficient is usually the planform area of the object (e.g, wings).
