What Can be Gained y Using a MSBN?
If a domain consists of loosely coupled subdomains, then...
- Knowledge acquisition is natural and modular: Subnet can be built one at a time.
- Inference requires only local computation. Attention shift uses only hyperpath. Hence computation is more efficient
- Answers to queries are the same as from a homogeneous BN.
