In emission tomography (ET), fast developing Bayesian reconstruction methods can incorporate anatomical information derived from co-registered scanning modalities, such as magnetic resonance (MR) and computed tomography (CT). We propose a Bayesian image reconstruction method for single photon emission computed tomography (SPECT), using a joint entropy (JE) similarity measure to embed MR anatomical...
Under the linear loss, we consider the test problem of the life parameter in the exponential distribution using empirical Bayes (EB) approach and present a monotone EB test possessing a rate of convergence which can be arbitrarily close to O(n-1) under the condition that the past samples are S\phiS-mixing.
The DNA microarray may contain missing expression data. Estimation of missing values is a necessary step in microarray analysis, because data mining procedures require a complete expression as their input. In this paper, we propose a missing data estimation algorithm, named KPCAimpute, based on kernel principal component analysis. We consider a family of heavy-tailed kernel functions, which is a generalization...
