Most real-world optimization problems are dynamic in nature. To deal with the optimization problems in a dynamic environment, a general framework inspired from immune system is proposed. Three types of subpopulations mimicking the states of B-cells are introduced. Among them, innate population globally explores the promising area, while adaptive population locally searches the optima, and the memory...
This paper presents a sparse representation (SR)-based selective ensemble learning method for Polarimetric SAR image classification. Sparse representation uses the least dictionary atoms which come from a structured dictionary to represent the data, however, different training samples will lead to different options of the selected atoms and the corresponding coefficients, which will lead different...
With multiple channels, Polarimetric SAR (PolSAR) contains abundant target information and anti-jamming ability, which can improve the ability of target discrimination and image interpretation. The classification problem of PolSAR has become one of the most urgent problems to be solved in PolSAR application with the improvement of PolSAR technology. Due to the complexity of multiple-dimensional classification,...
Among the various approaches to determine the true domain of fuzzy inference rules in the designing of fuzzy controller, the important one is to solve a system of fuzzy relation equations corresponding to the fuzzy inference sentence. In our earlier work, we gave a new method to construct the system and presented a method to solve the system when the system is consistent. But when the system is inconsistent,...
Radio resource management plays a major role in QoS provisioning for wireless/mobile networks. The scarcity and fluctuation of wireless link bandwidth, as well as the interconnection of wireless networks and Internet, motivate the research on adaptive multimedia services which have already run in Internet widely. The problem of seeking the optimal solution for revenue maximization is NP-hard, so the...
