Graphical model
Markov chain
Answer by choosing the correct option: In a Bayes' net, nodes represent:

Answer by choosing the correct option: One of the problems with using full joint distribution tables is:
They are too large to represent explicitly (unless there are only a few variables).
They are too easy to learn.
They don't represent dependencies.
They simplify the model too much.
They are always accurate.
