Probability Axioms & Rules

Kolmogorov’s axioms define probability as a measure on events: non-negativity, normalization, and countable additivity.

KL Divergence (Kullback-Leibler Divergence)

Kullback–Leibler (KL) divergence measures how one probability distribution P devotes probability mass differently from a reference distribution Q.
