The last few years have seen the appearance of a new sparse reference-based free energy principle, which demonstrates that an input visual signal was always strived to be comprehend by the human visual system (HVS) through removing the undetermined portions. By this inspiration, we in this paper put forward an image quality assessment (IQA) model based on sparse reference information. In essential, as compared with the classical good-performance FEDM model that was developed with a linear local autoregressive (AR) model, the proposed sparse reference (SR) IQA model is a simplified version of FEDM, achieving comparable performance but hundreds of times faster implementation. More specifically, this paper introduces the extremely sparse random sampling method into the FEDM model. Experimental results on the most well-known LIVE IQA database illustrate the effectiveness along with efficiency of our SR-IQA model as compared with the typical full-reference IQA models and the cutting-edge SR IQA models. © 2022, Springer Nature Singapore Pte Ltd.

In this paper, we present a SIFT based Slope K method which is faster and more robust than the classical SIFT in landmark based localization. First, the slope k value can be used to erase mismatched feature points (outliers) of the two compared images. Second, the y position is determined by the slope k value. Therefore, the Slope K method is able to localizes about twice as more accurate as the classical SIFT. Another advantage of the proposed method is that the number of database images needed to be matched is significantly reduced, compared to the classical SIFT. Therefore the time cost is approximate 4 times less than that of the classical SIFT.

The monitoring and fault detection for the Czochralski (Cz) crystal growth process is important to ensure the quality of the produced mono-crystalline silicon. The Cz process is a typical multi-modes industrial process, which makes the detection difficult in distinguish the change caused by the fault or mode switching. In this paper, an adaptive fault detection strategy for Cz crystal growth process is proposed. Firstly, quality-related variables are selected from numerous process variables, based on which the training dataset is constructed. Then, a fault detection model is built based on slowly-varying feature and statics indicator. A model switching strategy and updating algorithm are designed to handle the abnormal situation caused by the mode switching or fault occurrence. Three representative experiments are conducted to verify the performance of the proposed strategy, including numerical cases, a publicly available dataset, and Cz crystal growth process from our laboratory. © 1963-2012 IEEE.

There are three relations exist in Supply and Demand Network of Enterprises with Multifunction and Opening Characteristics (SDN) that are competition, cooperation and neutrality relations, which's evolutionary will effects the stability of SDN. To reveal the evolution process and interactive of the three relations among enterprises of SDN, an evolutionary game model in SDN was build to solve the problem of real cooperative strategy selection. The model of enterprises relations evolutionary was established base on evolutionary game theory, and analyzed with numerical simulations in MATLAB. The research shows that the strategy selection of cooperation, competition and neutrality in SDN were mainly determined by transferable and non-transferable incomes. Enhancing supervision and punishment to opportunistic behavior and malicious competition in SDN, will improve enterprises' relations from neutrality to cooperation. © Trade Science Inc.

To realize dynamic, open and multi supply-demand cooperation of Supply and Demand Network of Enterprises with Multifunction and Opening Characteristics (SDN), both the operational mode and implemented information platform were proposed, according to the restrictions existed in operational mode and service platform. A new operational pattern of SDN based on “full open, win-win cooperation” was propose, by bring service operator and platform provider in SDN. With “Decentralized resources centralize management, centralized resources dynamic service” as guidance, the information system framework of service-oriented SDN was proposed, the key technologies of SDN platform were discussed, the feature of service-oriented SDN were analyzed. Finally, a case of service-oriented SDN of small and medium-sized manufacturing enterprises was discussed. © 2014, Journal of Chemical and Pharmaceutical Research, All rights reserved.

Modeling and simulation of competition-cooperation and neutrality relations in SDN enterprises

引用

Journal of Chemical and Pharmaceutical Research 2014年第5期6卷 1714-1724页

Besides competition and cooperation, there also have neutrality relations, which is noncompetition and noncooperation, exists in Supply and Demand Network of Enterprises with Multi-function and Opening Characteristics (SDN). To reveal the evolution of cooperation, competition and neutrality relations among enterprises in SDN, an evolutionary model on node relations in SDN was build to solve the problem of real cooperative strategy selection. Base on evolutionary game theory, an enterprises relations evolutionary game model was established, and analyzed with numerical simulations in MATLAB. The results show that transferable and non-transferable incomes determined the choice of cooperation, competition and neutrality strategy. Opportunistic behavior and malicious competition exited in SDN, which reduced the overall revenue and destroyed the stability of SDN. Enhanced supervision and punishment in SDN will improve enterprises’ relations from neutrality to cooperation. © 2014, Journal of Chemical and Pharmaceutical Research. All right reserved.

A newly introduced Self-adaptive Differential Evolution algorithm via Generalized Opposition-Based Learning (SDE-GOBL) is applied to optimal design of two sewer networks. Every chromosome consists of the information of network layout. Select a feasible design which satisfies the constraints of velocity, slope and proportional water depth to get optimal cost through the algorithm. Two sewer optimization problems in which the pipe diameters are considered as the decision variables are solved by the SDE-GOBL algorithm. Comparisons with the previous works are made and the results show that the proposed algorithm performs better in terms of solution quality and efficiency.

第42届中国控制会议

作者： Yining Chen School of Artificial Intelligence Tiangong University Key Laboratory of System Control and Information Processing Ministry of Education

This paper mainly solves the containment control issue for a network of infinite-dimensional agents described by wave equations. To eliminate influences caused by external disturbances, observers based on partial differential equations are proposed. A novel interaction protocol is then designed to reach containment control under a fixed directed communication topology. Different from the existing works, disturbances with unbounded derivatives are allowed in this paper. A proper Lyapunov function is constructed and the sufficient condition assuring containment control is obtained. Finally, the theoretical results are verified via numerical examples.
