Belief versus temporal networks

• causality versus sequence
• Both deal with events and states
• Temporal: all events/states must happen
• Belief net may have instantaneous events
• BN roughly corr. with a temporal sequence
• Temporal is fully connected
• Belief is pointed not fully connected
  • with no joint, that's the point
  • not even reflexive/bidirectional
  • usually a polytree
• Could hybridize
  • both semantics on each arc
  • BN nodes could be temporal relationships
