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

On the regularization of extremal three-point functions involving giant gravitons
Physics Letters B, 2015 In the AdS5/CFT4 set-up, extremal three-point functions involving two giant 1/2 BPS gravitons and one point-like 1/2 BPS graviton, when calculated using semi-classical string theory methods, match the corresponding three-point functions obtained in the ...

On the VC-dimension, covering and separating properties of the cycle and spanning tree hypergraphs of graphs [PDF]
Transactions on Combinatorics, 2022 In this paper, we delve into studying some relations between the structure of the cycles and spanning trees of a graph through the lens of its cycle and spanning tree hypergraphs which are hypergraphs with the edge set of the graph as their vertices ...

Multi-decision tree prediction model for coal seam floor water inrush based on cost-sensitive theory
Gong-kuang zidonghua, 2020 When predicting coal seam floor water inrush, the situation is generally divided into two states: safe state and water inrush state. The state data has non-equilibrium characteristics.

Unfolding of Finite Concurrent Automata [PDF]
Electronic Proceedings in Theoretical Computer Science, 2018 We consider recognizable trace rewriting systems with level-regular contexts (RTL). A trace language is level-regular if the set of Foata normal forms of its elements is regular. We prove that the rewriting graph of a RTL is word-automatic.

Approximation hardness of dominating set problems in bounded degree graphs [PDF]
, 2008 We study approximation hardness of the Minimum Dominating Set problem and its variants in undirected and directed graphs. Using a similar result obtained by Trevisan for Minimum Set Cover we prove the first explicit approximation lower bounds for various

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