Transforming structures by set interpretations [PDF]
Logical Methods in Computer Science, 2007 We consider a new kind of interpretation over relational structures: finite sets interpretations. Those interpretations are defined by weak monadic second-order (WMSO) formulas with free set variables.

Scattering of conformal higher spin fields
Journal of High Energy Physics, 2018 We develop a formalism for describing the most general notion of tree-level scattering amplitudes in 4d conformal higher spin theory. As conformal higher spin fields obey higher-derivative equations of motion, there are many distinct on-shell external ...

Data mining of the GAW14 simulated data using rough set theory and tree-based methods [PDF]
BMC Genetics, 2005 Abstract Rough set theory and decision trees are data mining methods used for dealing with vagueness and uncertainty. They have been utilized to unearth hidden patterns in complicated datasets collected for industrial processes. The Genetic Analysis Workshop 14 simulated data were generated using a system that implemented multiple ...

BCJ numerators from differential operator of multidimensional residue
European Physical Journal C: Particles and Fields, 2020 In previous works, we devised a differential operator for evaluating typical integrals appearing in the Cachazo–He–Yuan (CHY) forms and in this paper we further streamline this method.

Event Tree Analysis of Xinda Oil Pipeline Leakage Based on Fuzzy Set Theory [PDF]
The Open Civil Engineering Journal, 2017 Event tree is a logical analysis of probability for outcome events by initiating event and probable subsequent events. However, the evaluation of every single event may contain vague information or cannot be described by a crisp number of probabilities in application.

A New Method to Identify Incomplete Frame of Discernment in Evidence Theory
IEEE Access, 2019 One assumption of Dempster-Shafer evidence theory (D-S theory) is the closed world. However, how to determine whether the frame of discernment is incomplete or not is still an open issue.

The research of fuzzy decision trees building based on entropy and the theory of fuzzy sets
Collection of selected papers of the IV International Conference on Information Technology and Nanotechnology, 2018 Decision trees are widely used in the field of machine learning and artificial intelligence. Such popularity is due to the fact that with the help of decision trees graphic models, text rules can be built and they are easily understood by the final user.

Optimization of mine ventilation network solution method based on rough set and WLS
Gong-kuang zidonghuaExisting mine ventilation network solution methods do not consider the distribution of error weights in the ventilation network during the solution process, which leads to deviations in the airflow of each branch and limits the accuracy of the results ...
