Compute the support and confidence for both rules.
Consider the data set shown in Table 7.8. The first attribute is continuous,
while the remaining two attributes are asymmetric binary. A rule is consid-
ered to be strong if its support exceeds 15% and its confidence exceeds 60%.
The data given in Table 7.8 supports the following two strong rules:
(i) {(1 ? A ? 2), B = 1}?{C = 1}
(ii) {(5 ? A ? 8), B = 1}?{C = 1}
s({(1 ? A ? 2), B = 1}?{C = 1})=1/6
c({(1 ? A ? 2), B = 1}?{C = 1})=1
s({(5 ? A ? 8), B = 1}?{C = 1})=1/6
c({(5 ? A ? 8), B = 1}?{C = 1})=1
