Ensemble methods use multiple classifiers to achieve better decisions than could be achieved using any of the constituent classifiers alone. However, both theoretical and experimental evidence have shown that very large ensembles are not necessarily superior, and small ensembles can often achieve better results. In this paper, we show how to combine a set of weak classifiers into a robust ensemble...
To evade Wi-Fi interference for ZigBee networks, it is required to reliably deliver critical channel-changing instructions under heavy interference. This paper firstly investigates ZigBee transmission performance under real-world Wi-Fi and under controlled high-rate data streams, respectively. Based on the experimental results, a theoretical model and a rough guideline for reliable message delivering...
A new synchronization control scheme is proposed for Lorenz system. In order to obtain global stability, a state-depended dynamical error equation for the coupled systems is addressed. The control problem is converted into matrix inequalities by choosing proper control parameters. Additional optimization is given to reduce control parameters. Finally, the control problem is numerically solved by BMI...
An attitude regulating control for a class of satellites is proposed. The control scheme is based on the orientation description of Rodrigues or Modified Rodrigues parameters. A method for initial value calculation of the Rodrigues/Modified Rodrigues parameters is given to transmit the stabilizing control into regulation. An attitude control for SAPPHIER satellite is studied. The proposed control...
