Let c1, c2, and c3 be the confidence values of the rules {p} ?? {q}, {p} ?? {q, r}, and {p, r} ?? {q}, respectively. If we assume that c1, c2, and c3 have different values, what are the possible relationships that may exist among c1, c2, and c3? Which rule has the lowest confidence?
What will be an ideal response?
Considering s(p) ? s(p ? q) ? s(p ? q ? r)
Thus: c1 ? c2 & c3 ? c2.
Therefore c2 has the lowest confidence.
