We investigate modal algebras that generalize the unary discriminator into two directions related to an ideal of the algebra. It turns out that some classes lead to well-known logics, while others have not yet been explored.

Confusion matrices and their associated statistics are a well established tool in machine learning to evaluate the accuracy of a classifier. In the present study, we define a rough confusion matrix based on a very general classifier, and derive vario

Based on Alasdair Urquhart’s representation of not necessarily distributive bounded lattices we exhibit several discrete dualities in the spirit of the “duality via truth” concept by Orlowska and Rewitzky. We also exhibit a discrete duality for

Suppose that $${\mathscr {N}}$$ is a set of subsets of a finite set Q. $${\mathscr {N}}$$ may be interpreted, for example, as a set of observed states as a result of an experiment or as a model of some theory. In a further step, the elements of $${\m

We present previously unknown algebraic semantics for Sobocinski’s logics S4.4, also known as \(\mathbf {S4.3DumB_2}\), and the autoepistemic logic KD45. The operators on the respective algebras are generalizations of the unary discriminator define

This book is dedicated to the work of Alasdair Urquhart. The book starts out with an introduction to and an overview of Urquhart's work, and an autobiographical essay by Urquhart. This introductory section is followed by papers on algebraic logic and

In previous work we have presented a class of algebras enhanced with two contact relations representing rough set style approximations of a spatial contact relation. In this paper, we develop a class of relational systems which is mutually interpreta
