Abstract :
A fast deblurring network, based on a high-performance convolutional network and pixel volume, is proposed to address the limitations of existing video deblurring algorithms, which often overly emphasize inter-frame information, leading to high algorithmic complexity. First, high-performance convolutional networks are utilized to prune the deblurring network, thereby reducing both the number of model parameters and computational complexity. To address the increased network computational complexity resulting from the extensive use of traditional two-dimensional convolutional layers, depthwise over-parameterized convolutions are employed to replace traditional convolutions. This substitution significantly reduces computational complexity without compromising the network's structure and performance. In addition, the Charbonnier loss function is used to approximate the mean absolute error (MAE) loss function to alleviate the over-smoothing problem. At the same time, the problem of non-differentiability of the MAE loss function at zero is solved by adding a constant, to enhance the visual quality of video images. Experimental results demonstrate that the proposed method delivers superior deblurring performance. Compared with the baseline pixel volume deblurring network framework, our method achieves a significant reduction in model complexity, demonstrating 28.73% fewer parameters and 59.96% lower floating-point operations, underscoring its theoretical significance.

Abstract :
Multi-view semi-supervised learning enables to efficiently leverage multi-view information as well as labeled and unlabeled data to solve practical problems. With graph neural networks, multi-view semi-supervised learning can be smooth and robust to the label propagation process. Hypergraph learning is an approach to hypergraph topology that aims to identify and exploit high-order relations on hypergraphs to uncover data beyond one-to-one in real-world applications. However, traditional hypergraph construction methods usually consider only local correlations between samples and may ignore dependencies that exist in the wider context of the dataset. In this paper, we propose a novel multi-view high-order correlation modeling method, where the connectivity of hyperedges is determined through clustering, and complementary information from each view is integrated via a hypergraph neural network. Inspired by the divisibility of graphs revealed by spectral graph theory, the proposed method works well to capture global high-order correlations within data and uncover potential manifolds. To assess the effectiveness of hypergraph modeling, we conduct a comprehensive evaluation of a multi-view semi-supervised node classification task. The experiments illustrate that the proposed approach achieves superior performance compared to current state-of-the-art algorithms and general hypergraph learning across eight datasets.

Abstract :
There are a lot of multi-objective optimization problems (MOPs) in the real world, and many multi-objective evolutionary algorithms (MOEAs) have been presented to solve MOPs. However, obtaining non-dominated solutions that trade off convergence and diversity remains a major challenge for a MOEA. To solve this problem, this paper designs an efficient multi-objective sine cosine algorithm based on a competitive mechanism (CMOSCA). In the CMOSCA, the ranking relies on non-dominated sorting, and the crowding distance rank is utilized to choose the outstanding agents, which are employed to guide the evolution of the SCA. Furthermore, a competitive mechanism stemming from the shift-based density estimation approach is adopted to devise a new position updating operator for creating offspring agents. In each competition, two agents are randomly selected from the outstanding agents, and the winner of the competition is integrated into the position update scheme of the SCA. The performance of our proposed CMOSCA was first verified on three benchmark suites (i.e., DTLZ, WFG, and ZDT) with diversity characteristics and compared with several MOEAs. The experimental results indicated that the CMOSCA can obtain a Pareto-optimal front with better convergence and diversity. Finally, the CMOSCA was applied to deal with several engineering design problems taken from the literature, and the statistical results demonstrated that the CMOSCA is an efficient and effective approach for engineering design problems.

Abstract :
Radial basis function network-based autoregressive with exogenous input (RBF-ARX) models are useful in nonlinear system modelling and prediction. The identification of RBF-ARX models includes optimization of the (model lags, number of hidden nodes and state vector) and the parameters of the model. Previous works have usually ignored optimizations of the model's architecture. In this paper, the RBF-ARX architecture, which includes the selection of lags, number of nodes of the RBF network, lag orders and state vector, is encoded into a chromosome and is evolved simultaneously by a genetic algorithm (GA). This combines the advantages of the GA and the variable projection (VP) method to automatically generate a parsimonious RBF-ARX model with a high generalization performance. The highly efficient VP algorithm is used as a local search strategy to accelerate the convergence of the optimization. The experimental results demonstrate the effectiveness of the proposed method.

Abstract :
Memory and reward have been proved as effective mechanisms for maintaining cooperation among selfish individuals. In this article, this study proposes a reward mechanism based on historical loyalty, that is, an individual who adhere to the cooperation strategy for a period of time will get additional reward. Accordingly, the reward for a loyal cooperator is undertaken by neighboring defectors equally. The results on prisoner's dilemma game show that, with appropriate loyalty threshold and reward factors, the cooperation level can be greatly enhanced. In addition, the time evolution of cooperator density and the spatial distribution of cooperators and defectors are also studied. (C) 2020 Published by Elsevier B.V.

Abstract :
We propose a punishment mechanism in the spatial public goods game with continuous strategies. The value of strategy denotes the amount that an individual contributes to each group. In a group, the ones who contribute the least will be punished by others and punishers equally share the associated costs. It is found that the punishment fine and the number of individuals being punished in a group play important roles in the evolution of cooperation. Compared with the case of no punishment, the cooperation level increases (decreases) when the number of individuals being punished is less (more) than half of the total number of individuals in a group. For a fixed value of the enhancement factor, the cooperation level increases (decreases) as the punishment fine increases when individuals being punished are the minority (majority) in a group.

Abstract :
It is well known that the feedback mechanism or the individual's intuitive response to the epidemic can have a vital effect on the disease's spreading. In this paper, we investigate the bifurcation behavior and the optimal feedback mechanism for an SIS epidemic model on heterogeneous networks. Firstly, we present the bifurcation analysis when the basic reproduction number is equal to unity. The direction of bifurcation is also determined. Secondly, different from the constant coefficient in the existing literature, we incorporate a time-varying feedback mechanism coefficient. This is more reasonable since the initiative response of people is constantly changing during different process of disease prevalence. We analyze the optimal feedback mechanism for the SIS epidemic network model by applying the optimal control theory. The existence and uniqueness of the optimal control strategy are obtained. Finally, a numerical example is presented to verify the efficiency of the obtained results. How the topology of the network affects the optimal feedback mechanism is also discussed.
