Then we move to the question of decidability. First-order deductive logic is well known to be undecidable and this undecidability carries over to inductive logic under the standard semantics, which holds that premisses inductively entail a conclusion just when every probability function that satisfies the premisses also satisfies the conclusion. It is perhaps surprising then that a large class of inferences in objective Bayesian inductive logic turns out to be decidable. We see that decidability is achieved by reducing the general inference problem to a problem involving only quantifier-free premisses, which can be solved using a truth-table method. This reduction permits the use of Bayesian networks to provide a potentially efficient approach to inference in objective Bayesian inductive logic.<\/p>\n<p>Joint work with Juergen Landes &amp; Soroush Rafiee Rad.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>For this talk a recording is available, click here.<\/p>\n<p>Speaker: Jon Williamson (University of Kent)<br \/>\nDate and Time: Wednesday, April&nbsp;26th 2023, 16:30-18:00<br \/>\nNote the unusual day!
