BCJ numerators from differential operator of multidimensional residue

open access: yesEuropean 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.

A New Method to Identify Incomplete Frame of Discernment in Evidence Theory

open access: yesIEEE 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.

Data mining of the GAW14 simulated data using rough set theory and tree-based methods [PDF]

open access: yesBMC 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 ...

Event Tree Analysis of Xinda Oil Pipeline Leakage Based on Fuzzy Set Theory [PDF]

open access: yesThe 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.

Building trees by juggling information and following rules: an expert interview study on tree-building and phylogenetic inference

open access: yesEvolution: Education and Outreach
Tree-thinking is a fundamental skill set for understanding evolutionary theory and, thus, part of biological and scientific literacy. Research on this topic is mostly directed towards tree-reading—the umbrella-term for all skills enabling a person to ...

Unbalanced Data Classification Based on Hesitant Fuzzy Decision Tree [PDF]

open access: yesJisuanji gongcheng, 2019
In order to optimize the classification effect of unbalanced data,an improved fuzzy decision tree algorithm is proposed combining the hesitant fuzzy set theory and the decision tree algorithm.The unbalanced data is oversampled by the SMOTE algorithm,the ...

The research of fuzzy decision trees building based on entropy and the theory of fuzzy sets

open access: yesCollection 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.

From Proof Nets to the Free *-Autonomous Category [PDF]

open access: yesLogical Methods in Computer Science, 2006
In the first part of this paper we present a theory of proof nets for full multiplicative linear logic, including the two units. It naturally extends the well-known theory of unit-free multiplicative proof nets.

Granulation Using Clustering And Rough Set Theory And Its Tree Representation

open access: yes, 2007
Granular computing deals with representation of information in the form of some aggregates and related methods for transformation and analysis for problem solving. A granulation scheme based on clustering and Rough Set Theory is presented with focus on structured conceptualization of information has been presented in this paper.
