An Association Rule is an implication of form A ⇒ B, where A ⊂ I, B ⊂ I , and A ∩B = φ. The rule A ⇒ B holds in the data set (transactions) D with supports, where ‘s’ is the percentage of transactions in D that contain A ∪ B (i.e., the union of set A and set B, or both A and B). This is taken as the probability, P (A ∪ B).Senior Content Strategist and BA Program Lead, Analytics Vidhya Pranav Dar Pranav is the Senior Content Strategist and BA Program Lead at Analytics Vidhya.
