반응형 Lift1 Interestingness Measure: Correlation Lift * Measure of dependent/correlated events: lift 1) Statistiacal independence P(S∩B) = P(S) x P(B) => Statistically independence P(S∩B) > P(S) x P(B) => Postively correlated P(S∩B) Negatively correlated 2) lift : interestingness measure: (interesting = reasonable 정도로 이해하면 될 것 같다) - if the lift is equal to 1, then A and B are independent and there is no correlation between them.
