Study Notes
Bayesian Networks
- A Bayesian network is a probabilistic graphical model that represents a set of variables and their conditional dependencies via a directed acyclic graph (DAG).
Alternative Name
- A Bayesian network is also known as a Bayes net or belief network.
Probabilistic Nature
- Bayesian networks are considered probabilistic because they model uncertainty using probability theory, allowing for the quantification of uncertainty and the updating of beliefs based on new evidence.
Graph Representation
- A Bayesian network is represented using a directed acyclic graph (DAG), which consists of nodes representing variables and edges representing conditional dependencies between variables.
Generalized Form for Decision-Making
- The generalized form of a Bayesian network for solving decision problems under uncertain knowledge is called an influence diagram, which extends the Bayesian network to include decision and utility nodes to model decision-making under uncertainty.
