Quantification of Temporal Fault Trees Based on Fuzzy Set Theory [PDF]

open access: yes, 2014
Fault tree analysis (FTA) has been modified in different ways to make it capable of performing quantitative and qualitative safety analysis with temporal gates, thereby overcoming its limitation in capturing sequential failure behaviour. However, for many systems, it is often very difficult to have exact failure rates of components due to increased ...

Binary classification based on a combination of rough set theory and decision trees

open access: yesInnovative Technologies and Scientific Solutions for Industries, 2023
The subject of the study is to improve the accuracy and efficiency of classification algorithms using decision trees by integrating the principles of Rough Set theory, a mathematical approach to approximating sets. The aim of the study is to develop a hybrid model that integrates rough set theory with decision tree algorithms, thereby solving the ...

Applications of cohomology to set theory II: Todorčević trees

open access: yesAnnals of Pure and Applied Logic, 1996
The author develops a cohomology theory for a class of \(\omega_1\)-trees. This continues the author's investigations in Part I [ibid. 71, 69-106 (1995; Zbl 0824.03029)] on application of cohomology to gaps. An \(\omega_1\)-tree \(T\) is special if there is a function \(f: T\to \mathbb{Z}\) such that if \(s< t\) then \(f(s)\neq f(t)\).

Decision Tree Construction based on Rough Set Theory under Characteristic Relation [PDF]

open access: yesProceedings on Intelligent Systems and Knowledge Engineering (ISKE2007), 2007
Several approaches based on rough set have been proposed for constructing decision tree in complete information systems. In fact, many information systems are incomplete in practical applications. In this paper, a new algorithm, Decision Tree Construction based on Rough Set Theory under Characteristic Relation (DTCRSCR), is proposed for mining ...

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.

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.

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.

A Decision Tree Algorithm Based on Rough Set Theory after Dimensionality Reduction

open access: yesInternational Journal of Computer Applications, 2011
Decision tree technology has proven to be a valuable way of capturing human decision making within a computer. As ID3 select those attribute as splitting attributes which have different values whether it classify dataset properly or not. There is another drawback of ID3 which repeat sub tree many times and select same attribute many times.
