The control strategy utilizes PID controller and CMAC to combine a composite controller. Outputs of multiple same composite controllers are mapped by MIMO linear neural networks into final control actions. Because of characteristics of neural networks, multivariate control system can approach reference model, and the decoupling control aim was achieved. The simulation results show that the strategy realized effectively decoupling control for multivariate coupling system, and is good at anti-disturbance ability and strong in robustness.

Although many cognitive parameter selection strategies are proposed, there is still much work need to do. This paper proposes an individual cognitive parameter setting method by simulating the black stork foraging process. It chooses the cognitive value of each particle associated with its age dominated by its performance. For particles whose performances is better than average performance of the swarm, their cognitive values is set between [1.5, 2.5], while other cognitive values are chosen between [0.5, 1.5]. Simulation results show the modified particle swarm optimization based on this phenomenon is superior to two variants of particle swarm optimization.","PeriodicalId":420853,"journal":{"name":"2009 8th IEEE International Conference on Cognitive Informatics","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129942951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Instead of direct embedding a message or image within the source image, choosing a window of size 2 × 2 of the source image in sliding window manner then convert it from spatial domain to frequency domain using Discrete Fourier Transform (DFT). The bits of the authenticating message or image are then embedded at LSB within the real part of the transformed image. Inverse DFT is performed for the transformation from frequency domain to spatial domain as final step of encoding. Decoding is done through the reverse procedure. The experimental results have been discussed and compared with the existing steganography algorithm S-Tools. Histogram analysis and Chi-Square test of source image with embedded image shows the better results in comparison with the S-Tools.","PeriodicalId":420853,"journal":{"name":"2009 8th IEEE International Conference on Cognitive Informatics","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114532981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a recent development in denotational mathematics known as granular algebra, which enables a rigorous treatment of computing granules as a generic abstract mathematical structure and granular behaviors as a set of algebraic operations. An abstract granule is modeled as a mathematical entity that elicits a set of basic properties of computing granules. Then, a set of algebraic operations on abstract granules is defined such as the relational, reproductive, and compositional operations. A real-world case study is presented that demonstrates how concrete granules and their algebraic operations are derived based on granular algebra. This work shows that granular algebra is not only a powerful conceptual modeling methodology for granular systems, but also a functional specification methodology for granular computing.","PeriodicalId":420853,"journal":{"name":"2009 8th IEEE International Conference on Cognitive Informatics","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114541323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Generally, online handwriting data is a multidimensional time series comprises of time series of pen-tips position (x, y), pressure, altitude, azimuth etc.. In case of person verification application, use of such multivariate data improves verification accuracy. However increase of data volume increases computational cost for analysis. In this study, in order to reduce data volume , we propose a new method for extraction of the basic feature points of multidimensional handwriting time series from the view point of testing determinism in the underlying dynamics behind handwriting. Proposed method is based on two-dimensional recurrence map of translation error. Basic feature points denote the principal points in the trajectory of handwriting dynamics to preserve the rough form of the individual's handwriting speciality. The simulation experiment has been done with SVC 2004 online handwriting signature data. The result shows that the basic feature point series is quite sufficient for analyzing the data for identity detection while the raw handwriting time series includes redundancy.","PeriodicalId":420853,"journal":{"name":"2009 8th IEEE International Conference on Cognitive Informatics","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115086187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
