Classification is one of the most important technologies used in data mining. Researchers have recently proposed several classification techniques based on the concept of association rules (also known as CBA-based methods). Experimental evaluations on these studies show that in average the CBA-based approaches can yield higher accuracy than some of conventional classification methods. However, conventional...
As an important component of passive media forensics (PMF), content-based copy detection (CBCD) is appropriate for identifying piracy of digital content and preventing falsified evidence. In this paper, we propose a novel and efficient CBCD scheme for identifying different altered versions of original images. We employ singular value decomposition (SVD) and block partition to improve the robustness...
Offering unified observer structure for a class of chaotic system, observer based projective synchronization method is proposed and synchronization condition for linear synchronization subsystem is theoretically analyzed in; here synchronization condition for nonlinear synchronization subsystem is theoretically analyzed, and applications of the observer based projective synchronization method are...
Based on a PWL memristor, Chua's circuit is modified through element replacement, simulation results demonstrated that chaos attractor can be generated in the modified Chua's circuit.
This paper deals with steering control problem of a computer simulated model car with fuzzy control approach. For simulating the real environment, the stochastic behavior of system is considered as multiplicative noise term. In addition, the external disturbance effect on system is also discussed for achieving attenuation performance by applying passivity theory. Through using the Takagi-Sugeno (T-S)...
In this paper, a predator-prey model with Beddington-DeAngelis function response and diffusion is studied. Uniform persistence of the system is discussed . The sufficient condition of local asymptotic stability and global asymptotic stability of the positive equilibrium is showed . Then, stability of the system is Simulated by Matlab.
