Geographical influence has been intensively exploited for location recommendations in location-based social networks (LBSNs) due to the fact that geographical proximity significantly affects users’ check-in behaviors. However, current studies only model the geographical influence on all users’ check-in behaviors as a universal way. We argue that the geographical influence on users’ check-in behaviors...
In this paper we discuss the problem of reduced-order anti-synchronization. By taking the three-order chaotic Genesio system as the drive system and the four-order hyper-chaotic Chen system as the response system, we design a scheme of reduced-order anti-synchronization with nonlinear control method. Then the exponential stability of the error dynamical system at origin is analyzed. Finally, some...
Least Squares Support Vector Machine (LS-SVM) is a classic algorithm for regression estimation and classification. But unfortunately, for really large problems, LS-SVM can become highly memory and time consuming. In this paper, we present a simplified algorithm for LS-SVM, called ILS-SVM, which effectively reduces the algorithmic complexity. In order to improve the rate of convergence and overcome...
