Abstract: Neural decoding is a technology to analyze intentions produced by neural activities, which has important applications in military, medical, entertainment and so on. As a typical application, decoding electromyogram (EMG) signals into corresponding gestures is an important content. In order to improve the accuracy of EMG signals recognition, researchers often extract effective features from EMG signals and classify gestures by constructing a reasonable classifier. However, because of the stochasticity of the signals, this method is not robust enough. This paper proposes a convolutional neural network (CNN) based on feature fusion, which can automatically learn and classify features from time-domain(TD) and …frequency-domain(FD). To make full use of information, two fusion methods are used and compared. Experiments show that the proposed fusion methods are superior to the traditional algorithm for both normal people and amputees, and have better performance compared with CNN method using only one kind of information.

Abstract: In traditional mechanism reliability analysis, probability theory or statistical approaches are employed. However, these methods cannot be used under lack of data and great epistemic uncertainty. In this paper, an advanced mechanism reliability analysis method is put forward based on uncertain measure. To satisfy the subadditivity of epistemic uncertainties, a novel uncertainty quantification method based on uncertainty theory is proposed for mechanism reliability analysis. Then, a point kinematic reliability analysis method combined with uncertain measure is presented to calculate the kinematic uncertainty reliability of motion mechanism at each time instant. Three models are developed for estimating kinematic uncertainty reliability. Furthermore, …first-order Taylor series expansion is used to solve nonlinear limit state functions. A new kinematic uncertainty reliability index (KURI) is presented based on normal uncertainty distribution. Finally, by applying the proposed method to a numerical experiment, the trend of uncertainty reliability was found to be consistent with the traditional method. The two practical engineering applications show that the presented method are more reasonable compared with the classical approaches when the information of design parameters is insufficient.

Abstract: We use the notion of fuzzy chromatic number (FCN) of fuzzy graphs based on fuzzy independent vertex sets introduced in 2015. Let G ˜ 1 be a path fuzzy graph and G ˜ 2 be any fuzzy graphs where their vertex sets are disjoint. Let G ˜ = G ˜ 1 □ G ˜ 2 be a cartesian product of G ˜ 1 and G ˜ 2 …. In this paper, we construct formula for FCN of G ˜ 1 □ G ˜ 2 and verify connection between maximum of FCN of both fuzzy graphs and FCN of their cartesian product. Also, we create an algorithm to determine FCN of the cartesian product according to the properties obtained. The last two statements show novelties of the present work. Evaluation of the algorithm is presented in the experimental results. Show more

Abstract: The structures of many molecules such as dendrimers, alkanes and acyclic molecules are like trees. Rooted trees have wide applications in chemical graph theory such as enumeration and encoding of chemical structures. Structures of chemical compounds can be systematized in form of chemical and empirical formulae through mathematical means. Chemists have a long tradition of using atomic valences (vertex degrees) to find molecular structures graphically. In structural chemistry number of graph applications exist. This paper reflects the work on the following indices: first general Zagreb index M α , general Randić connectivity index R α , general …sum-connectivity index χ α , atom-bond connectivity index ABC , geometric-arithmetic index GA , fourth atom-bond connectivity index ABC 4 , fifth geometric-arithmetic index GA 5 , hyper-Zagreb index HM  (G ), first multiple Zagreb index PM 1  (G ), second multiple Zagreb index PM 2  (G ) and Zagreb polynomials M 1  (G , x ) , M 1  (G , x ) for line graph of complete m -ary tree.

Abstract: In brain medical imaging, magnetic resonance is an important and effective means to support the computer aided diagnosis. Notwithstanding, inherent conditions such as atypical information, artifacts and vaguely delimited boundaries between existing tissues can hinder the segmentation task. A popular method to carry out this process is through Fuzzy C-Means algorithm, as well as its variants. These include the Intuitionistic Fuzzy C-Means algorithm, which is found suitable for brain magnetic resonance image segmentation, since it incorporates the advantage of intuitionistic fuzzy sets theory to handle the uncertainty. Most clustering algorithms depend of customized hand-crafted features as well as an appropriate …initialization process; this last aspect is a mandatory pre-requisite for convergence of the algorithm. In order to develop the brain image segmentation, in this paper we enhance the Intuitionistic Fuzzy C-Means performance by means of Robust Statistics. Explicitly, a non-parametric German-McClure Redescending M-Estimator is used at the initialization and clustering stages, it behaves such as a robust location estimator when the centroid vector is computed, and as a weighting when the membership matrix is updated. The fusion of both paradigms allows us to propose a clustering algorithm that develops efficiently the segmentation of magnetic resonance images, with the important merit of reduce the iteration required to converge. The robustness and effectiveness of this proposal is verified by experiments on simulated and real brain images. Show more

Abstract: Bayesian statistical inference is an important method of mathematical statistics in which both sample information and prior information are employed. Traditionally, it is often assumed that the sample observations from the population are observed precisely and characterized by crisp values. However, in many cases, the sample observations are collected in an imprecise way and characterized by uncertain values. In this paper, based on uncertain theory, we propose three kinds of uncertain Bayesian statistical inference including Bayesian point estimation, Bayesian interval estimation and Bayesian hypothesis test. Some numerical examples of uncertain Bayesian inference are presented to illustrate the proposed methods.

Abstract: The k-Nearest Neighbor (k-NN) is one of the simplest intelligent algorithms in the field of pattern recognition and classification. The increasing complexity of practical applications brings more uncertainty and fuzziness. In this paper, we take advantage of the Dempster-Shafer evidence theory (D-S evidence theory) and the hesitant fuzzy set (HFS) in depicting uncertain preference and information, and develop the evidence k-Nearest Neighbor (Ek-NN) under the hesitant fuzzy environment. The fruit fly optimization algorithm (FOA) is adopted to determine the most appropriate value of k in Ek-NN, and a specific implementation process of the optimized Ek-NN based on FOA is also …provided. Moreover, two numerical examples about classification problems are presented to evaluate the performance of the proposed method. Comparative analysis and sensitivity analysis are further conducted to illustrate the advantages of the optimized Ek-NN based on FOA under the hesitant fuzzy environment. Show more

Abstract: The emotional value of products, especially aesthetic qualities are conducive to increasing the market competitiveness along with the improvement of living standards. Therefore, the main purpose of this study is to combine the rough set theory and fuzzy quality function deployment design matrix to construct an innovative model, thus developing an aesthetic product design for customer satisfaction. Taking Blender as an example, the author divides this paper into three phases. Firstly, the author summarizes seven aesthetic qualities through the literature discussions and determines the core aesthetic qualities of Blender by making rough set theory attribute reduction and importance calculation. Secondly, …the results are imported into the fuzzy quality function deployment needs facet, and the correlation matrix is established by consulting the expert’s opinions to obtain the optimal combination of design features. Finally, the combination of the features produces a bio-conceptual shape via a bionics step. The results show that four out of seven aesthetic attributes (ie, concise, original, elegant, and comfortable) are found to be more significant. The optimal combination of product features are integrated with the bio-inspired method to generate three design solutions, in which the styling of butterfly concept effectively enhances the products’ emotional value and customers’ aesthetic satisfaction degree.

Abstract: The textile industry has a long history and a large market scale around the world. High-speed loom belongs to the high-end production equipment of the textile industry with the characteristics of high precision, high speed and high efficiency. However, due to its expensive cost and complex structure, there might be significant loss once a high-speed loom breaks down. At present, the monitoring and troubleshooting of high-speed loom operation mainly depend on the experience of maintenance people to carry out inspections, which is inefficient, time-consuming, laborious and less efficient. In this paper, a fault diagnosis method for high-speed loom based on …rough set and Bayesian network is investigated. Rough set theory is applied to reduce the attributes of fault causes and results and find the minimum reduction and classification rules. Then, a Bayesian fault diagnosis network model is built, and the probability of each fault cause is calculated to find the maximum probability. Finally, the diagnosis results are obtained. The experimental results have demonstrated the reliability and convenience of the faults diagnosis method for the high-speed loom. Show more

Abstract: This paper studies the flight path optimization problem of air cargo companies in aviation line alliance. There are two limitations in this paper. One is to limit of the number and location of airbases and capacity in the air network. The other is to limit of flight time and airspace capacity of full cargo aircraft in actual operation. Considering the influence of alliance on operation, the selection probability of air alliance is introduced. It is assuming that all cargo aircraft is one type, the unit transportation cost of every aviation line is the same as each other, the queuing problem …of aircraft landing is not considered, and the network transportation demand of itself must be completed by an airline. It proposes a directed aircraft fleet routing problem optimization model (SMDDDAAAFRPTW) with multi-airbase stochastic and time constraints to minimize total operating cost and flight distance. Using the multi-objective optimization algorithm NSGA-II by most scholars, and improving the initial solution generation step, introducing Genetic engineering into cross-mutation to solve the optimal number and location of air bases and fleet routing of multiple aircraft. Comparing with the weighted method and ant colony algorithm, it shows that the improved NSGA-II algorithm is effective and has better computational efficiency. The results show that the more segments are selected for outsourcing, the lowest cost of network and the lowest carbon emission. This kind of decision-making behavior is only suitable for the initial operation phase of the enterprise. Show more

Abstract: Automated visual inspection is becoming an important field of computer vision in many industries. The real-time inspection of flat surface products is a task full of challenges in industrial aspects that requires fast and accurate algorithms for detection and localisation of defects. Structural, statistical and filter-based approaches, such as Gabor Filter Banks, Log-Gabor filter and Wavelets, have high computational complexity. This paper introduces a fast and accurate model for inspection and localization of industrial flat surface products: Neighborhood Preserving Perceptual Fidelity Aware Mean Squared Error (NP-PAMSE). The Extreme Learning Machine (ELM) is used for classification. ELM is found to …be the perfect classifier for detecting defects. The proposed model resulted in defect detection accuracy of 99.86%, with 98.16% sensitivity, and 99.90% specificity. These results show that the proposed model outperforms many existing defect detection approaches. The discriminant power displays the efficiency of ELM in differentiation between normal and abnormal surfaces. Show more

Abstract: The quality of manufactured products plays a very important role in increasing consumer satisfaction. One approach to improving outgoing lot quality is applying screening method. In this paper, a multiple deferred state sampling plan is presented for a unilateral-univariate normal process with imprecise process quality in the presence of the rectifying inspection. To assess the performance of the proposed plan, a mathematical model is derived for calculating the fuzzy average total inspection ( ATI ˜ ) under the operation of the proposed plan. The obtained conclusions indicate that the proposed plan is more economical than the …existing plans in terms of ATI ˜ measure. A numerical example is given to demonstrate how to apply the introduced plan in the real world. Show more

Abstract: Multi-view subspace clustering arises in many computer visional tasks such as object recognition and image segmentation. The basic idea is to measure the same instance with multiple views. In this paper, we proposed two centralized joint sparse representation models, namely, Centralized Global Joint Sparse Representation (CGJSR) and Centralized Local Joint Sparse Representation (CLJSR) for multi-view subspace clustering. CGJSR and CLJSR force the concatenated representation matrix of all views and the representation matrix of each view to be sparse respectively. Both CGJSR and CLJSR allow the sparse coefficient matrix to approach a unified latent structure with an acceptable error. Noises and …outliers regularization terms are included in CGJSR and CLJSR to reduce the influence of noises and outliers. Related optimization problems are solved using the alternating direction method of multipliers. Compared with seven state-of-the-art multi-view clustering algorithms, our proposed algorithms can achieve better or comparable results on four real-world datasets. Show more

Abstract: As modern industrial processes often have multiple production modes, multimode-process monitoring has become an important issue. In multimode processes, the operating condition may often switch among different modes. As a result, popular process monitoring methods such as principal component analysis (PCA) and partial least squares (PLS) method should not be directly applied because they are based on a fundamental assumption that the process only has one stable operating condition. In this paper, a novel multimode-process data-standardization approach called double-weighted neighborhood standardization (DWNS) is proposed to solve the problem of multimode characteristics. This approach can transform multimode data into approximately single-mode …data, which follow a Gaussian distribution. By analyzing a concrete example, this study indicates that the DWNS strategy is effective for multimode data preprocessing. Moreover, a novel fault detection method called DWNS-PCA is proposed for multimode processes. Finally, a numerical example and the penicillin fermentation process are used to test the validity and effectiveness of the DWNS-PCA. The results demonstrate that the proposed data-standardization method is suitable for multimode data, and the DWNS-PCA process monitoring method is effective for detecting faults in multimode processes.

Abstract: There are numerous large-scale global optimization problems encountered in real-world applications including engineering, manufacturing, economics, networking fields. Over the last two decades different varieties of swarm intelligence and nature inspired based evolutionary algorithms (EAs) were developed and still. Among them, particles swarm optimization, Firefly algorithm, Ant colony optimization, Bat algorithm are the most popular and recently developed leading swarm intelligence based approaches. They are mainly inspired by the social and cooperative behaviors of swarm likewise herds of animals, flocking of birds, schooling of fish, ant colonies, herds of bisons and packs of wolves working together for their common benefit. Due …to easy implementation and high capability in achieving of absolute optimum, swarm intelligence based algorithms have attained a great deal attention in both academic and industrial applications. This paper proposes a hybrid swarm intelligence (HSI) algorithm that employs the Bat Algorithm (BA) and the Practical Swarm Optimization (PSO) as constituents to perform their search process for dealing with recently designed benchmark functions in the special session of the 2017 IEEE congress of evolutionary computation (CEC’17) [3 ]. The approximate solutions for most of the CEC’17 benchmark functions obtained by the suggested algorithm in its twenty five independent runs of trails are much promising as compared to its competitors.

Abstract: Shortest path (SP) optimization problems arise in a wide range of applications such as telecommunications and transportation industries. The main purpose of these problems is to find a path between two predetermined nodes within a network as cheaply or quickly as possible. Conventional SP problems generally assume that the arc weights are defined by crisp variables, though imprecise data have been lately incorporated into the analysis. The present study formulates the SP problem in a directed interval-valued triangular fuzzy network. The resulting interval-valued fuzzy SP (IVFSP) problem is converted into a multi objective linear programming (MOLP) problem. Then, a lexicographic …optimization structure is used to obtain the efficient solution of the resulting MOLP problem. The optimization process confirms that the optimum interval-valued fuzzy shortest path weight preserves the form of an interval-valued triangular fuzzy number. The applicability of the proposed approach is illustrated through an example dealing with wireless sensor networks. Show more

Abstract: The clonal selection algorithm(CSA) is a core method in artificial immune system, which is famous for its intelligent evolution in artificial intelligence application. However, There are some shortcomings in the algorithm, such as local optima and low convergence speed, which make its practical effects not ideal. Culture algorithm(CA) is driven by knowledge, which can significantly improve the evolutionary efficiency. Chaos mechanism can make the algorithm have better problem space coverage ability. Therefore, a culture&chaos-inspired CSA(CC-CSA) is proposed in this paper to deal with the problems mentioned before. CC-CSA adopts the double-layer evolutionary framework of CA to extract knowledge and guide …the crossover and chaotic mutation operation to complete the evolution process. The implicit knowledge is used to adaptively control the chaotic mutation scale, guide the individuals to jump out of the local optima, and realize the accurate search in the latter evolution cycle to gradually approach the optimal solution. It can be seen from the mathematical model analysis that CC-CSA can converge to the global optimal solution. Compared with the experimental results of the original CSA and its representative, up-to-date improved methods, CC-CSA has the fastest convergence speed and the best detection performances. It is also proved that CC-CSA can solve the problems of local optima and slow convergence speed by using the knowledge guidance of CA’s double-layer framework and good coverage ability of chaos mechanism to the problem space.

Abstract: The notion of fuzzy N -soft sets is a hybrid model, which is a more generalized framework than fuzzy soft sets. To investigate the objects of a reference set in medical field, which have uncertainties in data, can be correctly captured by proposed structures of novel decision-making methods, graded TOPSIS and graded ELECTRE-I methods, based on fuzzy N -soft sets (henceforth, (F , N )-soft sets). Both the proposed methods compute the decision-maker estimations in a more flexile and affluent way, as well as improve the reliability of the decisions, that depends on star ratings or grades for the purpose …of the modelization of decision-making problems in medical field. We show the importance and feasibility of proposed methods by applying them on real life example in medical field having ambiguities, that can be accurately occupied by this framework. Finally, we discuss the comparison analysis of both the proposed decision-making methods. Show more

Abstract: Accurate and efficient recognition of Parkinson’s disease is one of the prominent issues in the field of healthcare. To address this problem, different methods have been proposed in the literature. However, existing methods are lacking in accurately recognizing the Parkinson’s disease and suffer from efficiency problems. To overcome these problems faced by existing models, this paper presents a machine-learning-based model for Parkinson’s disease recognition. Specifically, a hybrid feature selection algorithm has been designed by integrating the Relief and ant-colony optimization algorithms to select relevant features for training the model. Moreover, the support vector machine has been trained and tested on …the selected features to achieve optimal classification accuracy. Additionally, the K-fold cross-validation technique has been employed for the optimal hyper-parameters value evaluation of the model.The experimental results on a real-world dataset, i.e., Parkinson’s disease dataset is revealed that the proposed system outperforms baseline competitors by accurately recognizing the Parkinson’s disease and achieving 99.50% accuracy on the selected features. Due to high performance is achieved our proposed method, we are highly recommended for the recognition of PD. Show more

Abstract: This work firstly proposes some weight adjusting and preference interfering methods to generate more suitable weight vector in two-tier multi-criteria decision making. The proposed models simultaneously consider the original weight information and subjective preferences of decision makers under interval numbers based evaluation environments. A recently proposed weights allocation method based on convex poset is applied to determine the weight vectors from subjective preferences. With well adjusted and melted weight information, some fuzzy comprehensive evaluations are realized by applying Shilkret Integrals with melted preferences. A numerical example with corresponding decision rules for online shop evaluation problem is also presented for practitioners …to refer to. Show more

Abstract: Consistency is related with reasonableness of the priority vector derived from a preference relation. In this paper, it is pointed out by an example that the existing consistency for the intuitionistic multiplicative preference relations (IMPR) is weak that the ranking or the optimal alternative could not always be derived from the given consistent IMPR. We provide a novel consistency for the IMPRs by the score function and accuracy function and characterize it with the S-normalized and A-normalized intuitionistic multiplicative priority vectors (IMPV). Then, we propose methods to check and reach the S-normalization, the acceptable consistency of the IMPR by its …local IMPVs. We also give some examples to show how the proposed methods work and make comparisons with the existing methods to demonstrate the advantages and disadvantages of the proposed methods. Show more

Abstract: In this paper, by considering the notion of pseudo-hoops, which introduced by Georgescu [10 ], we presented the concepts of n -fold filters in pseudo-hoop. Concerning ideas, we gave some related results. Also, we extended our definition to n -fold (positive) implicative and n -fold fantastic filters and investigated their properties and the relation among these n -fold filters. In particular, we proved that every n -fold fantastic and positive implicative filter is an n -fold implicative filter. Finally, we studied the quotient of these filters.

Abstract: In this paper we address the problem of dimensionality reduction of tensor data. There are three contributions in this paper. Local Homeomorphism is the intrinsic mathematical feature of manifolds and the basis of many manifold learning algorithms. However, these algorithms are developed for vector data, not suitable for tensor data. Our first contribution is to derive a tensor version of dimensionality reduction based on local homeomorphism. Tucker decomposition is widely used in dimensionality reduction of tensor data. However, Tucker decomposition without any regularization is actually a traditional subspace learning problem. Our second contribution is to propose a local homeomorphism regularized …Tucker decomposition and applies it to dimensionality reduction of tensor data, called dimensionality reduction of tensor data based on subspace learning and homeomorphism, SLLH for short. As far as dimensionality reduction is concerned, only the core tensor in Tucker decomposition is the target, while the mode product matrices are only by-products. Therefore, many algorithms absorb all these mode product matrices into a big matrix by using the conversion theorem of tensor algebra. However, in Tucker decomposition, each mode product matrix represents dimensionality reduction for a specific dimension of tensor. Our third contribution is to propose an iterative solution method for SLLH, in which each mode product matrix of the current iteration is calculated from other mode product matrices and the core tensor of the previous iteration. The core tensor is evolved iteratively from the iteratively-calculated mode product matrices. The experimental results presented in this paper show that the proposed SLLH outperforms many of the state-of-the-art algorithms. Show more
