Section 7.2.4 presented various ways of defining negatively correlated patterns. Consider Definition 3: "Suppose that itemsets X and Y are both frequent, that is, sup(X) ≥ min sup and sup(Y ) ≥ min sup, where min sup is the minimum support threshold. If (P(X|Y )+P(Y |X))/2 < ϵ, where ϵ is a negative pattern threshold, then pattern X ∪ Y is a negatively correlated pattern." Design an efficient pattern-growth algorithm for mining the set of negatively correlated patterns.

Scientists have changed the model of the atom as they have gathered new evidence. one of the atomic models is shown below. what experimental evidence led to the development of this atomic model from the one before it? a few of the positive particles aimed at a gold foil seemed to bounce back. the colors of light emitted from heated atoms had very specific energies. experiments with water vapor showed that elements combine in specific proportions. cathode rays were bent in the same way whenever a magnet was brought near them.
