Microblogs, a mixture of new media and social networks, is a hotbed of lurking users. It is meaningful to capture profiles for a lurking user in customized applications because a lurking user can receive all messages except for sending few messages in microblogs. However, it is difficult to capture profiles for a lurking user because of lacking its user-generated contents. In this paper, we propose...
Radar equation is a very important tool to evaluate a radar system, and an approximate derivation of colocated multiple-input multiple-output (MIMO) radar equation is presented in this paper. Firstly, we derive the Signal-to-Noise Ratio (SNR) improvement factor MN of the colocated MIMO radar array output compare to single-input single-output (SISO) radar array output employing coherent integration,...
The un-modeled systematic errors are inevitable in the process of GPS baseline solution. A single epoch algorithm based on the Empirical Mode Decomposition (EMD) is presented, which has the advantage of mitigating the error effects outside the mathematic model. EMD provides a new method for analyzing signals from a nonlinear viewpoint, and decomposes a time series into a finite and often small number...
Inspired by natural immune systems, Artificial Immune System (AIS) is an emerging kind of computational intelligence paradigm. The traditional immune algorithm and Ai-net for clustering still have the problems of training time-consumption and accuracy. In this paper, AIS Algorithm is improved with Quantum Mechanics theory and the Schro??dinger equation to add the idea of the energy level into the...
The objection of the standard support vector machine (SVM) is to achieve the maximum margin and control the generalization capability of SVM classifier. It only considers the punishment constraints, but does not introduce the within-class and between-class constraint projections. A novel robust discriminative support vector machines algorithm with pairwise constraint projections called CPSVM is discussed...
