Let X | µ ∼ N p (µ, v x I) and Y | µ ∼ N p (µ, v y I) be independent p-dimensional multivariate normal vectors with common unknown mean µ, and let p(x|µ) and p(y|µ) denote the conditional densities of X and Y. Based on only observing X = x, we consider the problem of obtaining a predictive distributionˆp(y |x) for Y that is close to p(y |µ) as measured by(More)
Let X|µ ∼ N p (µ, v x I) and Y |µ ∼ N p (µ, v y I) be independent p-dimensional multivariate normal vectors with common unknown mean µ. Based on only observing X = x, we consider the problem of obtaining a predic-tive densityˆp(y|x) for Y that is close to p(y|µ) as measured by expected Kullback–Leibler loss. A natural procedure for this problem is the(More)
— The achievable throughput of the entire cellular area is investigated, when employing fractional frequency reuse techniques in conjunction with realistically modelled imperfect optical fibre aided distributed antenna systems (DAS) operating in a multicell multiuser scenario. Given a fixed total transmit power, a substantial improvement of the cell-edge(More)
Let X|μ ∼ N p (μ, v x I) and Y |μ ∼ N p (μ, v y I) be independent p-dimensional multivariate normal vectors with common unknown mean μ. Based on observing X = x, we consider the problem of estimating the true predictive density p(y|μ) of Y under expected Kullback–Leibler loss. Our focus here is the characterization of admissible procedures for this problem.(More)

BACKGROUND In this study, we aim to identify key climatic factors that are associated with the transmission of Japanese encephalitis virus in areas located near the Three Gorges Dam, between 1997 and 2008. METHODS We identified three geographical regions of Chongqing, based on their distance from the Three Gorges Dam. Collectively, the three regions(More)
In this paper, we present a new multiuser detection algorithm based on step ant colony optimization. This algorithm accelerates the process of search by setting the parameters of basic ant colony optimization appropriately and meanwhile introduces a strategy of jumping out of the local optimal solution, thus it can approach the minimum probability of error(More)
