Download or read book A New Decision Tree Pruning Method Based on Rst written by Ming-Yang Wang and published by . This book was released on 2018 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pruning decision tree is an effective method to avoid the phenomena of overfitting. Various pruning methods have been proposed in many literatures. This paper gives a new decision tree pruning method based on Rough Set Theory (RST). According to the concept of explicit region in literature, this paper proposes two new concepts: depth-fitting ratio and error ratio to establish the new pruning strategy. Two thresholds c1 and c2 will be used to control the pruning extent. In addition, this paper gives a concrete example where it compares the new method with Pessimistic Error Pruning (PEP) which has proved the validity of the new one.
Download or read book Decision Tree Pruning Using Expert Knowledge written by Jingfeng Cai and published by VDM Publishing. This book was released on 2008 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decision tree technology has proven to be a valuable way of capturing human decision making within a computer. How to prune the decision tree is one of the research directions of the decision tree technique, but the idea of cost-sensitive pruning has received much less attention than other pruning techniques even though additional flexibility and increased performance can be obtained from this method. This dissertation reports on a study of cost-sensitive methods for decision tree pruning. A decision tree pruning algorithm called KBP1.0, which includes four cost-sensitive methods, is developed. The intelligent inexact classification is used for first time in KBP1.0 to prune the decision tree. Using expert knowledge in decision tree pruning is discussed for the first time. By comparing the cost-sensitive pruning methods in KBP1.0 with other traditional pruning methods on benchmark data sets, the advantage and disadvantage of cost-sensitive methods in KBP1.0 have been summarized. This research will enhance our understanding of the theory, design and implementation of decision tree pruning using expert knowledge.

Available in PDF, EPUB and Kindle. Book excerpt: Decision tree technology has proven to be a valuable way of capturing human decision making within a computer. It has long been a popular artificial intelligence (AI) technique. During the 1980s, it was one of the primary ways for creating an AI system. During the early part of the 1990s, it somewhat fell out of favor, as did the entire AI field in general. However, during the later 1990s, with the emergence of data mining technology, the technique has resurfaced as a powerful method for creating a decision-making program. How to prune the decision tree is one of the research directions of the decision tree technique, but the idea of cost-sensitive pruning has received much less attention than other pruning techniques even though additional flexibility and increased performance can be obtained from this method. This dissertation reports on a study of cost-sensitive methods for decision tree pruning. A decision tree pruning algorithm called KBP1.0, which includes four cost-sensitive methods, is developed. The intelligent inexact classification is used for first time in KBP1.0 to prune the decision tree. Using expert knowledge in decision tree pruning is discussed for the first time. By comparing the cost-sensitive pruning methods in KBP1.0 with other traditional pruning methods, such as reduced error pruning, pessimistic error pruning, cost complexity pruning, and C4.5, on benchmark data sets, the advantage and disadvantage of cost-sensitive methods in KBP1.0 have been summarized. This research will enhance our understanding of the theory, design and implementation of decision tree pruning using expert knowledge. In the future, the cost-sensitive pruning methods can be integrated into other pruning methods, such as minimum error pruning and critical value pruning, and include new pruning methods in KBP. Using KBP to prune the decision tree and getting the rules from the pruned tree to help us build the expert system is another direction of our future work.

Download or read book CyberPhysical Systems written by Kostas Siozios and published by CRC Press. This book was released on 2022-09-01 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: As systems continue to evolve they rely less on human decision-making and more on computational intelligence. This trend in conjunction to the available technologies for providing advanced sensing, measurement, process control, and communication lead towards the new field of Cyber-Physical System (CPS). Cyber-physical systems are expected to play a major role in the design and development of future engineering platforms with new capabilities that far exceed today’s levels of autonomy, functionality and usability. Although these systems exhibit remarkable characteristics, their design and implementation is a challenging issue, as numerous (heterogeneous) components and services have to be appropriately modeled and simulated together. The problem of designing efficient CPS becomes far more challenging in case the target system has to meet also real-time constraints.CyberPhysical Systems: Decision Making Mechanisms and Applications describes essential theory, recent research and large-scale usecases that addresses urgent challenges in CPS architectures. In particular, it includes chapters on:• Decision making for large scale CPS• Modeling of CPS with emphasis at the control mechanisms• Hardware/software implementation of the control mechanisms• Fault-tolerant and reliability issues for the control mechanisms• Cyberphysical user-cases that incorporate challenging decision making
