Two-Layered Logics for Paraconsistent Probabilitiesrator and the Belnap–Dunn logic. The first logic . (introduced in [.]) formalises a ‘two-valued’ approach where each event . has independent positive and negative measures that stand for, respectively, the likelihoods of . and .. The second logic . that we introduce here corresponds to ‘four-valued’

An Evidence Logic Perspective on Schotch-Jennings Forcingence logics’ have been introduced to deal with both of those issues. The semantics of these logics are based on neighbourhood or hypergraph frames. The neighbourhoods of a world represent the basic evidence available to an agent. On one view, beliefs supported by evidence are propositions derived fr

A Separation Logic with Histories of Epistemic Actions as Resourcesand resource decomposition means splitting of histories. This separation logic, called AMHSL, allows us to reason about the past: does what is true now depend on what was true in the past, before certain actions were executed? We show that the multiplicative connectives can be eliminated from a logi

Conditional Obligations in Justification Logicng conditional and contrary-to-duty obligations, such as those exemplified by the notorious Chisholm’s puzzle. We consider the alethic-deontic system (E) and present the explicit version of this system (JE) by replacing the alethic Box-modality with proof terms and the dyadic deontic Circ-modality w

Structural Completeness and Superintuitionistic Inquisitive Logicsstems that are not closed under uniform substitution. We just require that each logic must be closed under .-substitutions assigning to atomic formulas only .-free formulas. For these systems we introduce four different notions of structural completeness and study how they are related. We focus on s

Validity in Choice Logicsng a Hintikka-style semantic game [.] to a provability game. Strategies in the provability game are translated into proofs in a novel labeled sequent calculus where proofs come in degrees. Furthermore, we show that preferred models can be extracted from proofs.

Aleatoric Propositions: Reasoning About Coinsn. Rather than let propositions take a true/false valuation, we assume they act as a biased coin, that will sometimes land heads (.), and sometimes land tails (.). Complex propositions then correspond to a conditional series of tosses of these coins. We extend the syntax and semantics for Aleatoric

A Principled Approach to Expectation Maximisation and Latent Dirichlet Allocation Using Jeffrey’s Upf latent variables, and for finding an allocation of topics for a collection of documents. A recent insight in probabilistic learning is that Jeffrey’s update rule gives a decrease of Kullback-Leibler divergence. Its logic is error correction. It is shown that this same rule and divergence decrease
