A mixture of multiple linear classifiers is famous for its efficiency and effectiveness to tackle nonlinear classification problems. Each classifier contains one linear function multiplied with a gated function, which restricts its corresponding classifier to a local region. Previous researches mainly focus on the partition of local regions, since its quality directly determines the performance of...
The high coupling coefficient of wireless charging coupler can improve the transmission efficiency. To obtain higher coupling coefficient and lighter weight for double D (DD) coupler, the equivalent magnetic circuit and the expression of coupling coefficient are derived, which give some guidence for magnetic core optimization. Then different core structures are designed and compared by 3D Maxwell...
Kernel functions based machine learning algorithms have been extensively studied over the past decades with successful applications in a variety of real-world tasks. In this paper, we formulate a kernel level composition method to embed multiple local classifiers (kernels) into one kernel function, so as to obtain a more flexible data-dependent kernel. Since such composite kernels are composed by...
With the increasing demand of transmission speed and more robust quality of service, the capacity constrained backhaul gradually becomes bottleneck in cooperative wireless networks, e.g. in Joint Processing mode of LTE-Advanced Pro. This paper focuses the fact of resource allocation with limited backhaul capacity in uplink cooperative networks, where two base stations (BS) equipped with single-antenna...
Optimal queueing control of multi-hop networks remains a challenging problem even in the simplest scenarios. In this paper, we consider a two-hop half-duplex relaying system with random channel connectivity. The relay is equipped with a finite buffer. We focus on stochastic link selection and transmission rate control to maximize the average system throughput subject to a half-duplex constraint. We...
Most existing works about scheduling and resource allocation for orthogonal frequency division multiplexing (OFDM) based two-way relay networks have focused on immediate relay forwarding. In this paper, we consider relay buffering in delay-tolerant networks. The relay node is aided by two buffers and one for each user, so that it can adaptively decide when to buffer the received packets or to forward...
A kind of software test data automated generation method based on genetic algorithm and tabu search algorithm is proposed. Having both local search capabilities of tabu search algorithm and global search capability of genetic algorithm, this tabu genetic algorithm combines tabu search algorithm with genetic algorithm. The experiment results show that the tabu genetic algorithm with tabu search as...
