Convergence Analysis on Immune Optimization Solving CCP Problems

This work concentrates on studying the property of convergence of a sample allocation-based immune optimization approach used in solving linear or nonlinear chance-constrained programming (CCP) with general random variables. First, we make some theoretical studies about existence of optimal reliable solutions and give an approximate relation between the true CCP and the sample average approximation problem, depending on some statistic and analysis theory. Second, a bio-inspired immune optimization approach is developed to assume solving CCP problems. Our theoretical analysis shows that such approach, which is capable of being formulated by a non-homogeneous Markov model, is convergent. Experimentally, performance searching curves reveal that the approach can obtain valuable performances including the optimized quality, noisy suppression and convergence.

Study on the Importance of Cultural Context Analysis in Machine Translation

Context of culture affects the specific meaning of the language. So the analysis of cultural context is essential for Machine Translation (MT). If the cultural context analysis of the source language is omitted in MT, ambiguity or mistranslation will be produced. The paper analyzes briefly the present situation of MT first and then, based on the theory of cultural context, it discusses with examples the importance of cultural context analysis in MT. The paper holds that if the cultural context analysis is paid enough attention in MT, the literal meaning and cultural connotation of source language can be exactly and completely translated into target language so as to improve the quality of MT. Therefore, the large-scale context corpus is very necessary for MT.

A Soft Subspace Clustering Algorithm Based on Multi-Objective Optimization and Reliability Measure

Subspace clustering finds clusters in subspaces of the data instead of the entire data space to deal with high-dimensional data. Most existing subspace clustering algorithms lean on just one single objective function. Single objective function is often biased. On the other hand, most existing subspace clustering algorithms are based on wrapper approach, which brings a negative effect on the quality of subspace clustering. This paper presents a soft subspace clustering algorithm based on multi-objective evolutionary algorithm and reliability measure, called R-MOSSC. Comparing with optimization of a scalar function combining multiple objectives, it does not need to determine weight hyperparameters, and offers a deep insight into the problem by obtaining a set of solutions. Further, reliability-based dimension weight matrix from filter approach is used to enhance the performance of subspace clustering. Simulation results show that R-MOSSC is better than existing algorithms.

An Outlier Detection Method for Robust Manifold Learning

Manifold learning algorithms have been widely used in data mining and pattern recognition. Despite their attractive properties, most manifold learning algorithms are not robust to outliers. In this paper, a novel outlier detection method for robust manifold learning is proposed.

Motif Identification Based on Local Structure Clustering

Network motif identification is significant in that motifs generally reflect functionalities. However, the task is greatly challenging due to diverse patterns of motifs possibly existent in a network and high computation complexity for large scale networks. In this study, we propose a network motif identification method, FCMD, based on clustering subgraphs according to their local structures. By modeling local-topological feature of a network with a feature vector, the approach maps motif identification problem into a clustering problem of feature vectors in a feature space, which greatly reduces computation complexity hence facilitates very large scale networks. Experiments on 8 real networks, including biochemical network, neural network, electronics circuit network, et al., indicates that the proposed method is very effective in motif detection with computation complexity approximately independent to the scale of the network.

Computation of Synchronic Distance in Marked S-net

Synchronic distance is an important analyzing metric to describe the synchronic relationship between two events. Due to the difficulties to calculate the synchronic distance, which is determined by both the structure characteristics and the initial marking of the net system, no simple and feasible algorithms have been presented to get the synchronic distance of normal Petri nets. However, the computations of synchronic distance in some special subclass of Petri nets, such as marked T-graph, marked S-graph, and marked T-net, are relatively simple and feasible. The solution of the synchronic distance in another subclass of Petri net-marked S-net, is given in this paper. The synchronic distance of the marked S-net is directly obtained according to the structure of the net systems and the distribution situation of initial marking, which makes the solution of the synchronic distance become more feasible. The corresponding solution theorems are also given in the paper.

A Framework for Density Weighted Kernel Fuzzy c-Means on Gene Expression Data

Clustering techniques have been widely used for gene expression data analysis. However, noise, high dimension and redundancies are serious issues, making the traditional clustering algorithms sensitive to the choice of parameters and initialization. Therefore, the results lack stability and reliability. In this paper, we propose a novel clustering method, which utilizes the density information in the feature space. A cluster center initialization method is also presented which can highly improve the clustering accuracy. Finally, we give an investigation to the parameters selection in Gaussian kernel. Experiments show that our proposed method has better performance than the traditional ones.

An Epidemic-Dynamics-Based Model for CXPST Spreading in Inter-Domain Routing System

We study the CXPST attack which aims at the destruction of inter-domain routing system and propose a spreading model to represent the threatening scale. By analyzing the process we illuminate the mechanism of how CXPST seizes the BGP deficiencies to paralyze the Internet control plane from the traffic attack of data plane, and then the spreading model named as EDM-CS is presented based by the epidemic dynamics theory. Parameters of the model are closely associated with the real network topology and BGP router overloading condition which reflect the features of the CXPST spreading. In virtue of the classical BA scale-free network, spreading density that derives from EDM-CS behaves great consistency with the simulation results based on the collected data from CAIDA. This model can help understanding CXPST attack and providing a basis for predicting the spreading trend, as well as investigating effective defense strategy.

An Approach for Diversity and Convergence Improvement of Multi-Objective Particle Swarm Optimization

To improve the diversity and convergence of multi-objective optimization, a modified Multi-Objective Particle Swarm Optimization (MOPSO) algorithm using Step-by-step Rejection (SR) strategy is presented in this paper. Instead of using crowding distance based sorting technique, the SR strategy allows only the solution with the least crowding distance to be rejected at one iteration and repeat until the predefined number of solutions selected. With introduction of SR to the selection of particles for next iteration, the modified algorithm MOPSO-SR has shown remarkable performance against a set of well-known benchmark functions (ZDT series). Comparison with the representative multi-objective algorithms, it is indicated that, with SR technique, the proposed algorithm performs well on both convergence and diversity of Pareto solutions.

Optimization Analysis of Dynamic Sample Number and Hidden Layer Node Number Based on BP Neural Network

Taking use of BP neural network theory, a cyclic search method between dynamic training samples number and dynamic hidden nodes number is proposed to improve the prediction accuracy of network model. By increasing the training samples one by one to control the network training, searching dynamic sample error expectation matrix, and finally getting the best training sample number, with the goal of minimum error expectations. Thus, through the optimization model of hidden nodes number, searching the number of hidden layer nodes of network minimum output error. The results of the analysis of examples shows that, with the increasing number of training samples, the network output error expectation experienced three stages, namely recurrent big error stage, yield decline error stage and stable small error stage. But with the increasing number of hidden layer nodes, the result is on the contrary. This shows that proper number of training samples and hidden layer nodes is of great significance to improving the output precision of neural network.

Membrane computing is an emergent branch of bio-inspired computing, which provides a novel idea to solve computationally hard problems. In this paper, a new point pattern matching algorithm with local elitism strategy is proposed based on membrane computing models. Local elitism strategy is used to keep good correspondences of point pattern matching found during the search, so the matching rate and the convergence speed are improved. Five heuristic mutation rules are introduced to avoid the local optimum. Experiment results on both synthetic data and real world data illustrate that the proposed algorithm is of higher matching rate and better stability.

Prediction of Coal Calorific Value Based on a Hybrid Linear Regression and Support Vector Machine Model

The gross calorific value (GCV) is an important property defining the efficiency of coal. There exist a number of correlations for estimating the GCV of a coal sample based upon its proximate and ultimate analyses. These correlations are mainly linear in character although there are indications that the relationship between the GCV and a few constituents of the proximate and ultimate analyses could be nonlinear, which has made artificial intelligence models as a useful tool for a more accurate GCV prediction. This paper focuses on an innovative method of GCV prediction using combination of Multivariate Linear Regression (MLR) as predictor and Support Vector Machine (SVM) as an error correction tool based on proximate and ultimate analyses. The GCV have been predicted using the MLR, ANN and the hybrid MLR–SVM models. In the analysis root mean squared error have been employed to compare performances of the models. Results demonstrated that both models have good prediction ability; however the hybrid MLR–SVM has better accuracy.

New Ideas for FN/RFN Queries Based Nearest Voronoi Diagram

While most research focuses on nearest neighbor (NN) and reverse nearest neighbor (RNN) queries, the furthest neighbor (FN) and reverse furthest neighbor (RFN) query are attracting more and more attention. In this paper, we give new ideas on the FN/RFN query issue. The nearest Voronoi diagram-based (VD-based) algorithms to process FN and RFN queries on 2-dimensional location data on the fly is proposed. These algorithms are especially useful for applications which have VD as their fundamental structure. Instead of constructing a new furthest neighbor diagram (FD), we aim to fully utilize the properties of VD. Besides, we implemented our new methods as well as the most promising competing methods which have been previously proposed. The results consistently indicate that our new algorithms outperform competitors.

Video Summarization by Robust Low-Rank Subspace Segmentation

Video summarization provides condensed and succinct representations of the content of a video stream. A static storyboard summarization approach based on robust low-rank subspace segmentation is proposed in this paper. Firstly, video frames are represented as multi-dimensional vectors, and then embedded into a group of affine subspaces using low-rank representation according to the content similarity of the frames in the same subspace. Secondly, a series of subspaces are segmented based on the Normalized Cuts algorithm. The video summary is finally generated by choosing key frames from the significant subspaces and ranking these key frames in temporal order. The experimental results demonstrate that the proposed summarization algorithm can produce crucial key frames and effectively reduce the visual content redundancy in summary comparing with the conventional approaches.

Nanostructure Thin-Film Removal via a Cylinders Tool for Computer Touch Sensing Material

This study describes a precise method for the electro-chemical removal of defective tin-doped indium oxide (ITO) thin film from the surface of polyethylene terephthalate (PET) touch screen material using a newly designed multi-cylinder electrode tool. In the current experiment, a small gap-width between the cylindrical cathodes and anodes and the workpiece reduces the time taken to remove a particular amount of ITO by dissolution. A large diameter cathode rotational circle also reduces the time taken for effective ITO film removal because the dissolution effect is facilitated by the provision of sufficient electrochemical power. High rotational speed of the multi-cylinder tool and a high electrolyte flow rate also corresponds with an increase in the dissolution rate of the defective ITO layer. A small diameter of either the anode or cathode combined with enough electric power also results in faster dissolution. The removal rate of the ITO layer is also improved by a reduction in the number of cylinders used. This tool design was found to be most effective for the electrochemical removal of defective ITO thin film nanostructures and can remove the material easily and cleanly in a very short time. This newly designed tool and ultra-precise reclamation process can be used very effectively in the optoelectronics semiconductor industry for the removal of defective ITO layers from PET touch screen substrate to allow the material to be returned to the production line. This recycling will reduce both production costs and pollution.

Image Representation and Recognition Based on Directed Complex Network Model

Image structure representation is a vital technique in the image recognition. A novel image representation and recognition method based on directed complex network is proposed in this paper. Firstly, the key points are extracted from an image as the nodes to construct an initial complete undirected complex network. Then, the k-nearest neighbor evolution method is designed to form a series of directed networks. At last, the feature descriptor of the image is constructed by concatenating the structure features of each directed network to finally achieve image recognition. Experimental results demonstrate that the proposed method outperforms the traditional methods in image recognition and can describe the structure of images more effectively.

Fast Distributed BFS Solution for Edge-Disjoint Paths

We propose an improved synchronous distributed message-based breadth-first search (BFS) solution, to identify maximum cardinality sets of edge-disjoint paths, between a source node and a target node in a digraph. Previously, we presented a BFS based algorithm, NW-BFS-Edge (Nicolescu R, Wu H (2011) BFS solution for disjoint paths in P systems. In: Calude C, Kari J, Petre I, Rozenberg G (eds.) Unconventional computation, lecture notes in computer science, vol. 6714. Springer Berlin, pp 164–176), Nicolescu R, Wu H (2012) New solutions for disjoint paths in P systems. Nat Comput 11:637–651, which is a distributed version of the Edmonds-Karp algorithm Edmonds J, Karp RM (1972) Theoretical improvements in algorithmic efficiency for network flow problems. J ACM 19(2):248–264. Here, we propose a faster solution, Fast-NW-BFS-Edge, which improves NW-BFS-Edge by detecting and discarding “dead” cells in the first search round. On a set of randomly generated single-source directed acyclic graphs (dags), Fast-NW-BFS-Edge is 8.2 % faster than NW-BFS-Edge. This improvement has been inspired and guided by a P system modelling exercise, but is suitable for any distributed implementation.

Canonical Duality for Radial Basis Neural Networks

Radial Basis Function Neural Networks (RBF NN) are a tool largely used for regression problems. The principal drawback of this kind of predictive tool is that the optimization problem solved to train the network can be non-convex. On the other hand Canonical Duality Theory offers a powerful procedure to reformulate general non-convex problems in dual forms so that it is possible to find optimal solutions and to get deep insights into the nature of the challenging problems. By combining the canonical duality theory with the RBF NN, this paper presents a potentially useful method for solving challenging problems in real-world applications.

A Comparison of Actual and Artifactual Features Based on Fractal Analyses: Resting-State MEG Data

Future standardized system for distinguishing actual and artifactual magnetoencephalogram (MEG) data is an essential tool. In this paper, we proposed the quantitative parameters based on fractal dimension (FD) analyses in which the FD may convey different features before and after artifact removal. The six FD algorithms based on time-series computation, namely, box-counting method (BCM), variance fractal dimension (VFD), Higuchi’s method (HM), Kazt’s method (KM), detrended fluctuation analysis (DFA), and modified zero-crossing rate (MZCR) were compared. These approaches measure nonlinear-behavioral responses in the resting-state MEG data. Experimental results showed that the FD value of actual MEG was increased statistically in comparison with the artifactual MEG. The DFA and the HM present a best performance for analyzing simulated data and resting-state MEG data, respectively.
