Community Question Answering (CQA) sites have become valuable repositories that host a massive volume of human knowledge. How can we detect a high-value answer which clears the doubts of many users? Can we tell the user if the question s/he is posting would attract a good answer? In this paper, we aim to answer these questions from the perspective of the voting outcome by the site users. Our key observation...
Based on the pattern time delay shift coding regime, a structure of positive and negative frequency modulation calling pulses of underwater ultra-short base line acoustic positioning system is given, and the second correlation method of time delay estimation is proposed in this paper. As the second correlation method improves the detectable signal-to-noise ratio of calling end to certain extent, it...
This empirical study explores the structure of customer individual innovation behavior (CIIB) of Chinese service industry. According to the theory of individual innovation behavior(IIB) and the specific characteristics of customer involved in service innovation, we develop the CIIB scale. Exploratory factor analysis (EFA) of data from a sample of 242 customers shows that CIIB has there dimensions:...
A novel semi-blind defocused image deconvolution technique is proposed, which is based on RBF neural network and iterative Wiener filtering. In this technique, firstly a RBF neural network is trained in wavelet domain to estimate defocus parameter. After obtaining the point spread function (PSF) parameter, iterative Wiener filter is adopted to complete the restoration. We experimentally illustrate...
