This paper investigates the relationship between the singular vector of G̿D and the Fourier basis for solving inverse scattering problems. By operating SVD of the operator G̿D, G̿D behaves as a low-pass filter, which guarantees the drop-off of high frequency components. Importantly, such a relationship is determined by the domain of interest and the grid mesh, independent of scatterers, which can...
This paper proposes a framework for matting identification photos automatically. We firstly adopt image processing operations such as skin detection, k-means clustering, Grab cut segmentation and canny operator to generate a trimap with three regions, i.e., background, foreground and unknown regions. Then, we improve the Bayesian matting by introducing an alpha regularization term. Experiments demonstrate...
Creation and sustenance of long-term relationships with their customers is a key success factor in make-to-order manufacturing firms. In order to achieve both maximum cumulative profit and long-term profitable customer relationships, we integrate customer value into order acceptance decision. Then we use linear programming to model the order acceptance problem, and solve it with reinforcement learning...
Under the frame of national public finance, some risks often hide in the running course of the local government finance. Now, in China, local government investment and financing platforms have accumulated many debts, which become the important source of risk of local government finance. It is of far-reaching realism meaning to analyze and discuss the risk of local finance to resolve the whole risk...
