Uncertainty in Intelligent Systems

The International Journal of Approximate Reasoning is intended to serve as a forum for the treatment of imprecision and uncertainty in Artificial and Computational Intelligence, covering both the foundations of uncertainty theories, and the design of intelligent systems for scientific and engineering applications. It publishes high-quality research papers describing theoretical developments or innovative applications, as well as review articles on topics of general interest.

Relevant topics include, but are not limited to, probabilistic reasoning and Bayesian networks, imprecise probabilities, random sets, belief functions (Dempster-Shafer theory), possibility theory, fuzzy sets, rough sets, decision theory, non-additive measures and integrals, qualitative reasoning about uncertainty, comparative probability orderings, game-theoretic probability, default reasoning, nonstandard logics, argumentation systems, inconsistency tolerant reasoning, elicitation techniques, philosophical foundations and psychological models of uncertain reasoning.

Domains of application for uncertain reasoning systems include risk analysis and assessment, information retrieval and database design, information fusion, machine learning, data and web mining, computer vision, image and signal processing, intelligent data analysis, statistics, multi-agent systems, etc.

The journal is affiliated with the Society for Imprecise Probability: Theories and Applications (SIPTA), and Beliefs functions and Applications Society (BFAS).

Special Issue on Set-Based Methods for Reliable Modeling, Identification, Decision Making, and Simulation
Submission Date: 2026-02-28

The special issue on “Set-Based Methods for Reliable Modeling, Identification, Decision Making, and Simulation” presents selected research papers that are based on presentations given during the International Symposium on Scientific Computing, Computer Arithmetic, and Verified Numerical Computations (SCAN). Its 20th edition will be held in Oldenburg, Germany, from the 22nd to 26th of September 2025.

Over the last decades, SCAN has become an important meeting place for researchers from the fields of reliable computing, software engineering, and uncertainty quantification and those from such wide and varied application areas as robotics, control, structural and civil engineering, and signal processing. The goal is, on the one hand, to put into practice modern findings in verified methods to assess the influence of uncertainty caused by modeling errors, model order reduction, or numerical methods in a rigorous manner. On the other hand, problems from practice give new impulse for theoretical developments in verification.

With this special issue, we intend to continue the tradition of publishing high-quality post-proceedings of the series of SCAN symposia on the basis of a thorough review of the latest, not yet published research results. The special issue will enhance the visibility of SCAN in the community of uncertainty modeling and quantification, both from theoretical and applied perspectives.
