Abstract: The regions obtained by image segmentation need to satisfy both the requirements of uniformity and connectivity. Image segmentation is the process of dividing an image into several specific regions. The result of image segmentation is a set of combinations covering the main feature areas of the whole image. The pixels in an area are similar to some or calculated characteristics, but there are obvious differences between adjacent areas. In this paper, a gray image segmentation algorithm based on fuzzy C-means combined with bee colony algorithm is proposed, which has strong optimization ability for multi-objective problems. By using the fuzzy membership …function of the fuzzy C-means algorithm, the optimal clustering centers in the artificial bee colony optimization algorithm can be quickly calculated. It makes image segmentation faster and more accurate. The bee colony search algorithm is optimized and an effective local search algorithm is designed, it makes the bee colony converge to the optimal solution efficiently. Finally, the improved fuzzy C-means and artificial bee colony optimization algorithm are used to improve and optimize the seed region growth method. The multi-criteria are taken as the multi-objective optimization problem, and the segmentation results are finally obtained. Benefiting from our local search program and feature extraction in multi-color space, it makes the stability; efficiency and accuracy of image segmentation are higher. Show more

Abstract:  The complex-value-based generalized Dempster–Shafer evidence theory, also called complex evidence theory is a useful methodology to handle uncertainty problems of decision-making on the framework of complex plane. In this paper, we propose a new concept of belief function in complex evidence theory. Furthermore, we analyze the axioms of the proposed belief function, then define a plausibility function in complex evidence theory. The newly defined belief and plausibility functions are the generalizations of the traditional ones in Dempster–Shafer (DS) evidence theory, respectively. In particular, when the complex basic belief assignments are degenerated from complex numbers to classical basic belief assignments (BBAs), …the generalized belief and plausibility functions in complex evidence theory degenerate into the traditional belief and plausibility functions in DS evidence theory, respectively. Some special types of the generalized belief function are further discussed as well as their characteristics. In addition, an interval constructed by the generalized belief and plausibility functions can be utilized for fuzzy measure, which provides a promising way to express and model the uncertainty in decision theory.

Abstract: At present, indoor intrusion detection technologies based on WLAN are widely applied to protect the privacy of users and have a robust anti-interference ability under the condition of the Non-line-of-sight (NLOS), which become the mainstream topics of domestic and foreign studies. Most of the existing researches rely on the signal strength to train heuristic models, while the relationship between intrusion targets and signal fluctuations is not explored fully. In this circumstance, this paper proposes a novel indoor intrusion detection method based on fuzzy membership degree and Dempster-Shafer Theory (DST). First of all, the correlation between WLAN signal fluctuation features and …locations of intrusion targets are converted into DST mass function by fuzzy membership. Second, the reliability values from each MP are combined to select reliable reference positions by using the reliability combination rules in DST. Finally, the positions of the intrusion target are calculated based on the weighted maximum likelihood and centroid method. Finally, the related experimental results show that the proposed approach can not only ensure the high accuracy of intrusion detection but also obtain ideally accurate locations of the intrusion target.

Abstract: The digital media technology major is a multi-disciplinary and multi-disciplinary discipline. The cultivated talents should be based on applied talents. According to the traditional practice teaching methods, the disciplines are no longer suitable for the discipline. Colleges and universities strengthen the practice teaching reform of the digital media technology profession. It is a very important and necessary means. The purpose of this paper is to realize the evaluation of the reform effect of AVG comprehensive practice in digital media art through fuzzy theory. In this paper, the fuzzy comprehensive evaluation method is used to comprehensively evaluate the AVG practice of …digital media art. Because the fuzzy comprehensive evaluation method is very restrictive to the index weight, it cannot be well adapted to the system. In this paper, the processing scheme of the index weight value of the fuzzy comprehensive evaluation method is interval data, so that the algorithm can be better applied in the system. In the determination of weight, this paper uses the improved entropy weight method to determine the weight of the index. By comparing with other algorithms that obtain the weight of the index, it can be concluded that using the improved entropy weight method to obtain the weight value can not only effectively reduce the external interference. Moreover, the weight value obtained can well reflect the importance of the indicator. The experimental results show that the dynamic variability of fuzzy set theory can satisfactorily meet the comprehensiveness and reliability of AVG comprehensive practice reform evaluation results. Therefore, the application of fuzzy set theory in the field of AVG comprehensive practice reform effect evaluation is reasonable and accurate. Show more

Abstract: All along, the identification of night-driving safety car features is a major research direction in the field of intelligent traffic management, with a wide range of applications and development space, and these identification technologies include theoretical knowledge and important theoretical research in many fields. Due to the interference of lights and other light sources, the gray value of the background area also changes frequently. A common method during the day is to detect these background areas as moving vehicles, which greatly reduces the detection accuracy. The most reliable information at night is the headlights. If the light can be accurately …detected and other sources are excluded, accurate detection can be performed and tracking accuracy can be guaranteed. Vehicle safety assisted driving technology is one of the main research directions of intelligent transportation systems. It mainly uses computer technology, sensor technology and communication technology to collect and analyze the state information of roads, other vehicles and drivers. Provide advice and warnings to the driver before reaching the danger, determine current traffic conditions and avoid traffic accidents in advance. This paper studies some problems of night vehicle target recognition and detection, mainly the division of target and background, and the classification and recognition of target extraction. To solve these problems, a particle filter algorithm is introduced to introduce nonlinear statistics. The fuzzy theory is introduced to classify the video processed by the particle filter algorithm. The target recognition is realized by the method, and the purpose of identifying the night vehicle target is achieved. Comparative experimental analysis shows that this method is more accurate and powerful than the common target recognition algorithm and can be applied to real scenes. Show more

Abstract: With the rapid development of database and Internet technologies, data collection and storage is possible. It is often impossible to correctly analyze the valuable information contained in the data, and it becomes more difficult to obtain valuable information. Therefore, it faces the status of “rich data and scarce knowledge”. Traditional information processing technology can no longer meet the needs of reality. There is an urgent need for more capable and effective information processing skills to help us analyze the information we need from big data and guide us to make the right decisions. Data mining technology is born in the …background. Data mining technology is one of the effective methods to solve rich data and improve lack of knowledge. It is also one of the main research topics in the field of information science. Related research and applications have greatly improved people’s decision-making ability. It has been recognized as one of the extremes of data research and has a very broad application prospect. Large databases often contain redundant and unnecessary attributes for many search rules, so the ability to remove duplicate attributes can greatly improve the clarity of potential system knowledge and reduce the time complexity of finding rules. At the same time, it enables efficient operation and improved adaptability. Because the structure of the neural network is variable, it has strong self-organization, self-learning, nonlinearity and high fault tolerance, but the ability to express and interpret knowledge is very poor. The network parameters lack physical meaning and learning. Therefore, it has become an inevitable trend to form a fuzzy neural network combining the characteristics of the two. Therefore, exploring the organic combination between rough sets and fuzzy neural networks is undoubtedly of great significance for data mining technology research. This paper proposes a data mining method based on the combination of rough set and fuzzy neural network technology. Using the approximate set to discover the rules of the database rules, the initial structure of the fuzzy neural network is determined, and the training data is used to train the network. Since the fuzzy neural network thus constructed has a good topology of data distribution features from the beginning, the network scale can be greatly reduced and the network training speed can be improved.

Abstract: With the advent of Web 3.0 era, the number and complexity of Web pages in Bayesian networks have shown an explosive growth trend. Accompanying this is the geometric growth of information contained in Web pages. Web text data in Bayesian networks usually hide rich knowledge and rules of user value. However, due to the semi-structured, real-time and discrete characteristics of Web text data, it is difficult for users to obtain the knowledge they need directly from such complex data sets. The emergence of fuzzy mathematics provides a good research idea and method for solving such problems. It can use the …idea of fuzzy mathematics to analyze the practical problems in text data. Therefore, how to effectively mine the Web text data information and knowledge that users really care about from Bayesian network, and present it in a way that users can understand, it is a very popular research topic at present.

On the basis of the above research contents, the research results of Web text mining technology and fuzzy arithmetic mathematics are combined, design and implement information acquisition and analysis for Bayesian network community. The recall rate obtained by the experimental method in this paper is as low as 4%, and tends to be more stable. Show more

Abstract:  With the development and popularization of electronic computers and the Internet, the problem of language barriers has once again become prominent in the new era, and people are more in need of machine translation. However, there is currently no suitable method for effective semantic ordering of English machine translation. In order to better perform semantic ordering on English machine translation, the article combines fuzzy theory to construct an algorithm model, and analyzes the experimental results through evaluation indicators. The results show that with the increase of training concentration training examples, the semantic parser can learn more natural language sentence analysis …methods from the training examples, and the natural language sentences that can be correctly parsed gradually increase, so with the training examples increased recall rate and F value gradually increased.

Abstract: The fuzzy control algorithm is used to establish the relation between the functions of motion of 6-DOF (degree of freedom) industrial robots on the rotation angle of each joint. The algorithm optimizes the motion path of the robot, thereby accelerating the increase in industrial productivity and promoting the development of industrial production. During the motions, the 6-DOF industrial robots have weak avoidance ability toward the encountered obstacles, which is not conducive to the safe production and will reduce industrial efficiency. Therefore, by analyzing and summarizing the previous researches, the fuzzy control algorithm is used to construct and optimize the kinematics …model, thereby proposing a method of robot motion path planning. Also, based on the unstructured operating environment, a multi-functional motion navigation system for 6-DOF industrial robots is proposed. The experimental results show that the fuzzy control algorithm can optimize the robot motion path, shorten the time of motion, and make the robots reach the destinations smoothly. The algorithm can avoid safety accidents in industrial production effectively, reduce casualties, improve industrial productivity, and promote the optimized allocation of human resources. The motion system of 6-DOF industrial robot based on fuzzy control algorithm has excellent practicability, which can promote the development of industrial production effectively and be widely applied to industrial production.

Abstract: The data of time series are massive in quantity and not conducive to subsequent processing. Therefore, the unordered time series fuzzy clustering algorithm of adaptive incremental learning has been utilized to explore the segmentation of time series in further. The research results show that the emergence of incremental learning technology can solve such problems. Also, it can continuously accumulate and increase the data, as well as improving the learning accuracy. Incremental learning technology correctly processes, retains, and utilizes the historical results, thereby reducing the training time of new samples by using historical results. Therefore, the clustering algorithm mostly clusters the …cluster-liked shape of discrete datasets and uses the hierarchical clustering algorithm, which is more suitable for measuring the similarity of time series, to replace the Euclidean distance for distance metric and hierarchical clustering. The distance matrix update method is improved to reduce the computational complexity, which proves that the algorithm has higher clustering validity and reduces the operating time of the algorithm.

Abstract: Three-dimensional reconstruction technology can display the three-dimensional graphical data of medical images to diagnostic personnel, so as to facilitate multi-dimensional and multi-level observation of patient data, and assist doctors in qualitative and quantitative analysis of pathological tissue. A surface reconstruction algorithm for three-dimensional medical images based on segmentation is proposed.

A common method is to use a single sensor to establish a coal rock identification system, …and use the neural network algorithm as the core algorithm of the system. Therefore, this paper proposes a recognition system based on wavelet packet decomposition and fuzzy neural network. A variety of sensors are used to collect the response signal of the shearer, and then the multi-signal feature extraction and data fusion of the coal-rock interface identification method are realized, thereby improving the recognition rate. On the basis of the physical simulation system of coal and rock interface, a large number of tests were carried out, and a large amount of test data was collected through experiments.

The wavelet packet energy method is used for feature extraction, which completes the conversion from mode space to feature space, and provides reliable and accurate feature level data for data fusion. The results show that neural networks and genetic neural networks can be trained and simulated using experimental data. Data fusion based on genetic neural network can perform state recognition and has high recognition accuracy.

Abstract: With the development of Internet technology, the growth of network services is accelerating. For more and more network service requests, how to ensure the response speed and query accuracy required by users is a huge challenge. In order to realize fast clustering of large data business request data and improve the accuracy of clustering. This paper presents a data fuzzy clustering algorithm based on Adaptive Incremental learning time series. The algorithm defines large data clustering in time series, and the incremental time series clustering method is used. Firstly, the complexity of network data is reduced by data compression, and then …time series data clustering based on service time similarity is carried out. In this paper, the time series fuzzy clustering algorithm based on Adaptive Incremental Learning inherits the clustering structure information obtained by previous clustering. Initialize the current clustering process, and then search the outlier samples in the current data block adaptively without setting parameters. Automatically create new clusters from outlier samples, and finally check empty cluster recognition. Identification determines whether certain clusters need to be deleted to ensure the efficiency of subsequent cluster processes. The experimental results show that the algorithm has good clustering accuracy and efficiency for isochronous and unequal time series. Show more

Abstract: In multiattribute decision making problem, it is usually that the opinions of agent may be influenced by close friends or people with similar interests among his social network. This situation could act on the evaluation process of agent toward candidates, thereby affecting the overall two-sided matching results. This paper proposes a framework based on social network analysis. It can effectively achieve multiattribute social network matching that the relative weights of influencers are unknown before. In the proposed framework, the complete trust assessment matrix can be obtained through depicting the trust propagation relationship between agent and influencers. According to the trust …assessment result, a nonlinear optimization model is developed to calculate the unknown weights of influencers, and then the obtained weights of influencers are integrated into the two-sided evaluation process. Furthermore, two multi-objective optimization models are constructed to manage the rational agents and conservative agents. Based on the multi-objective optimization models, we generate the optimal matching pairs. Finally, detailed comparison analysis and discussion are presented to check the effectiveness of the proposed social network matching method. Show more

This model describes the dynamic interaction between labour share and the employment rate in an economy. One can use p -fuzzy systems to obtain solutions for differential equations whose the vector field are uncertain and partially known. The proposed p -fuzzy system is based on a fuzzy rule-based systems whose fuzzy rules represent economic premises described in the Goodwin model. We use two approaches to adjust the fuzzy terms of the corresponding fuzzy rule base from the economical data of a given …country. The first approach is based on statical measures and the second one uses fuzzy c-means clustering method.

First, STL-SVM uses the maximum mean discrepancy to measure the weight vector of the source domain samples relative to the target domain, and selects samples from the source domain according to each weight to avoid negative transfer. Then, the knowledge in the source domain is learned by the approximate extreme point support vector …at the minimum training data cost. Finally, the object function is constructed by the obtained knowledge and the soft-margin SVM. In the constraint conditions of the objective function, the learned knowledge that is highly correlated with the target domain is selected, and further, the phenomenon of negative transfer is avoided in principle. STL-SVM solves the problem of negative transfer, and has considerable advantages in training time efficiency compared with the existing algorithms. The experimental results on artificial and real datasets show the effectiveness of the proposed algorithm. Show more

Abstract: In recent years, there has been an increased interest in processing fuzzy queries over XML data that is also possibly fuzzy. Attention has been paid to various extensions of XML query languages that introduce concepts of fuzzy theory. We propose an extension of the XQuery query language in an attempt to handle flexible queries that provide priority, threshold, and fuzzy expression as well as fuzzy linguistic labels allowing users great flexibility in customizing query constraints. We give a detailed description of an advanced query processing software system developed using GPFCSP (Generalized Prioritized Fuzzy Constraint Satisfaction Problem) as the theoretical background. …The software, called FXI (Fuzzy XQuery Interpreter), was developed as a web application using Java, AngularJS, and eXist-db — an open source native XML database and it incorporates various advanced features such as fuzzy ordering operations and fuzzy compatibility calculations that includes priorities. The paper presents its design, the most important considerations related to implementation, as well as testing using realistic scenarios. Show more

Abstract:  Along with increasing and extension of uncertain set theory in decision making, ordering and ranking of uncertain sets have significantly become relevant, that is, an uncertain set needs to be evaluated and compared with the others. This paper introduces the size relation between two uncertain sets. It derives a formula to calculate the uncertain measure that an uncertain set is less than or equal to another one. Moreover, some examples are given to illustrate the size relation of uncertain sets. Finally, clustering is proposed as an application.

Abstract:  Fuzzy measures are used for modeling interactions between a set of elements. Simplified fuzzy measures, as k -maxitive measures, were proposed in the literature for complexity and semantic considerations. In order to analyze the importance of a coalition in the fuzzy measure, the use of indices is required. This work focuses on the generalized interaction index, gindex . Its computation requires many resources in both time and space. Following the efforts to reduce the complexity of fuzzy measure identification, this work presents two algorithms to compute the gindex for k -maxitive measures. The structure of k -maxitive measures makes …possible to compute the gindex considering the coalitions at level k and, for each of them, the number of coalitions sharing the same coefficient (called inheritors). The first algorithm deals with the space complexity and the second one also optimizes the runtime by not generating, but only counting, the number of inheritors. While counting the number of descendants is easy, this is not the case for the number of inheritors due to all the inheritors of previous considered coalitions have to be taken into account. The two proposed algorithms are tested with synthetic k -maxitive measures showing that the second algorithm is around 4 times faster than the first one. Show more
