*Inference in a Single-agent Oriented MSBN
Inference using LJF of a MSBN
- Queries of a single user are focused on a single JT at a time, where a query has the form “what is the probability of event A given that B has occured?”
- Evidence can be entered incrementally to the JT and queries are answered by local computation only .
- As the user shifts attention to another JT, belief propagation is performed only along the hyperpath to the target JT in the hypertree.
- Queries can then be entered at the target JT as above.
Theorem: After finite times of attention shifts, answers to queries computed locally are idential to what would be obtained from an equivalent homogeneous BN.
