Maximum a posteriori (MAP) adaptation and its discriminative variants, such as MMI-MAP (maximum mutual information MAP) and MPE-MAP (minimum phone error MAP), have been widely applied to acoustic model adaptation. This paper introduces a new adaptation approach, fMPE-MAP, which is an extension to the original fMPE (feature minimum phone error) algorithm, with the enhanced ability in porting Gau...

Let M2 be the space of quadratic rational maps f : P 1 → P , modulo the action by conjugation of the group of Möbius transformations. In this paper a compactification X of M2 is defined, as a modification of Milnor’s M 2 ' CP , by choosing representatives of a conjugacy class [f ] ∈ M2 such that the measure of maximal entropy of f has conformal barycenter at the origin in R, and taking the clos...

Although concept maps have been found to be effective in science education research, these are critiqued for being informal due to informal usage of relation and attribute names thereby resulting in ambiguity. Refined concept mapping, a development over the regular concept mapping is an approach towards introducing rigor and parsimony in representing knowledge. The method proposed suggests to s...

In this note, we show that some F -harmonic maps into spheres are global maxima of the variations of their energy functional on the conformal group of the sphere. Our result extends partially those obtained in [15] and [17] for harmonic and p-harmonic maps.

There has recently been increased interest in the use of Markov Chain Monte Carlo (MCMC)-based Bayesian methods for estimating genetic maps. The advantage of these methods is that they can deal accurately with missing data and genotyping errors. Here we present an extension of the previous methods that makes the Bayesian method applicable to large data sets. We present an extensive simulation s...

Turbo coding is the most commonly used error correcting scheme in wireless systems resulting in maximum coding gain. In this paper, a comparative study of the symbol-bysymbol maximum a posteriori (MAP) algorithm, its logarithmic versions, namely, Log-MAP and Max-Log-MAP decoding algorithms used in SISO Turbo Decoders are analyzed. The performance of Turbo coding algorithms are carried out in te...

Multipoint lod scores are typically calculated for a grid of locus positions, moving the putative disease locus across a fixed map of genetic markers. Changing the order of a set of markers and/or the distances between the markers can make a substantial difference in the resulting lod score curve and the location and height of its maximum. The typical approach of using the best maximum likeliho...

We propose a revised map of plant geographical regions for the Southern Levant (most of Israel, the Palestinian Territories and Jordan). Since this region has been heavily impacted by human activity over millennia we have created a detailed natural vegetation map using GIS, remote sensing and a species distribution model (MAXENT). We created an extensive database of over 1800 historical and fie...

Suppose that we start with a “prior” probability distribution g(θ) on parameters, which represents our knowledge (such as the frequencies of the 4 different nucleotides in the DNA of a given species) before running an experiment. Next, we run an experiment (e.g., sequencing a particular segment of DNA), and observe an outcome x. Bayes’s rule tells us that P (θ|x) = P (x|θ)g(θ) P (x) . In the ra...
