Learning Probabilities: Towards a Logic of Statistical Learning

no code implementations22 Jul 2019 Alexandru Baltag, Soroush Rafiee Rad, Sonja Smets

The most widespread model for such situations of 'radical uncertainty' is in terms of imprecise probabilities, i. e. representing the agent's knowledge as a set of probability measures.

Argument-based Belief in Topological Structures

no code implementations27 Jul 2017 Chenwei Shi, Sonja Smets, Fernando R. Velázquez-Quesada

In our combined setting, we use a topological semantics to represent the structure of an agent's collection of evidence, and we use argumentation theory to single out the relevant sets of evidence through which a notion of beliefs grounded on arguments is defined.

On the Solvability of Inductive Problems: A Study in Epistemic Topology

no code implementations24 Jun 2016 Alexandru Baltag, Nina Gierasimczuk, Sonja Smets

We investigate the issues of inductive problem-solving and learning by doxastic agents.

Revisable Justified Belief: Preliminary Report

no code implementations27 Mar 2015 Alexandru Baltag, Bryan Renne, Sonja Smets

We introduce a theory $\mathsf{JCDL}$ of Justified Conditional Doxastic Logic that replaces conditional belief formulas $B^\psi\varphi$ by expressions $t{\,:^{\psi}}\varphi$ made up of a term $t$ whose syntactic structure suggests a derivation of the belief $\varphi$ after revision by $\psi$.
