prior probabilities or marginal probabilities
conditional probabilities
axioms of probability
full joint probability distribution
specifies the probability of each complete as- signment of values to random variables. It is usually too large to create or use in its explicit form
Absolute independence
Absolute independence between subsets of random variables allows the full joint dis- tribution to be factored into smaller joint distributions, greatly reducing its complexity. Absolute independence seldom occurs in practice.
Bayes’ rule
Conditional independence
brought about by direct causal relationships in the domain might allow the full joint distribution to be factored into smaller, conditional distri- butions.
naive Bayes
The naive Bayes model assumes the conditional independence of all effect variables, given a single cause variable, and grows linearly with the number of effects.
