Statistically thinned arrays are obtained by thinning a reference filled array, according to probabilistic law that is dictated the current. The remaining radiators still separated commensurable distances, even if randomly located. Hence, wideband operations prevented grating lobes’ occurrence. To overcome above limitation, new and simple strategy presented in this article for deploying element...
In likelihood inference we usually assume the model is fixed and then base inference on the corresponding likelihood function. Often however the choice of model is rather arbitrary, and there may be other models which fit the data equally well. We study robustness of likelihood inference over such “statistically equivalent” models, and suggest a simple “envelope likelihood” to capture this aspe...
In many data exploration tasks it is meaningful to identify groups of aribute interactions that are specic to a variable of interest. For instance, in a dataset where the aributes are medical markers and the variable of interest (class variable) is binary indicating presence/absence of disease, we would like to know which medical markers interact with respect to the binary class label. ese ...
Basic color terms were originally defined by Berlin and Kay based on linguistic definitions and refer to a subset of color expressions that are universal across languages. In this paper, we investigate and report that basic color terms demonstrate much stronger statistical characteristics that differentiate them from other color words. We introduce a probabilistic interpretation of color naming...
Statistical methods have long been the dominant approach in speech recognition and probabilistic modelling in ASR is now a mature technology. The use of statistical methods in other areas of spoken dialogue is however more recent and rather less mature. This paper reviews spoken dialogue systems from a statistical modelling perspective. The complete system is first presented as a partially obse...
In this paper we study the feasibility of using standard deformable model fitting techniques to accurately track the deformation and motion of the human eye. To this end, we propose two highly detailed shape annotation schemes (open and close eyes), with +30 feature landmark points, high resolution eye images. We build extremely detailed Active Appearance Models (AAM), Constrained Local Models ...
We analyzed birth order differences in means and variances of height and body mass index (BMI) in monozygotic (MZ) and dizygotic (DZ) twins from infancy to old age. The data were derived from the international CODATwins database. The total number of height and BMI measures from 0.5 to 79.5 years of age was 397,466. As expected, first-born twins had greater birth weight than second-born twins. W...
