High-yield quick reference

Theory‑1 focus — full workings under "Theory" tab

Entropy (Info gain): Info(D) = − Σ pᵢ log₂(pᵢ), i = 1..m classes

Info needed after split on A: Info_A(D) = Σ (|Dⱼ|/|D|) × Info(Dⱼ)

Information Gain: Gain(A) = Info(D) − Info_A(D) (pick attribute with MAX gain)

Support: support(A⇒B) = P(A∪B) Confidence: confidence(A⇒B) = P(B|A) = support_count(A∪B) / support_count(A)

Apriori property: every non-empty subset of a frequent itemset must also be frequent (anti-monotone)
