Network inference using informative priors.
Recent years have seen much interest in the study of systems characterized by multiple interacting components. A class of statistical models called graphical models, in which graphs are used to represent probabilistic relationships between variables, provides a framework for formal inference regarding such systems. In many settings, the object of inference is the network structure itself. This ...
متن کاملVerb Class Disambiguation Using Informative Priors
Levin’s (1993) study of verb classes is a widely used resource for lexical semantics. In her framework, some verbs, such as give, exhibit no class ambiguity. But other verbs, such as write, have several alternative classes. We extend Levin’s inventory to a simple statistical model of verb class ambiguity. Using this model we are able to generate preferences for ambiguous verbs without the use o...
متن کاملHighly Informative Priors
SUMMARY After discussing the role of prior information in statistical inference, historically and in current problems, we analyze the problem of seasonal adjustment i n economics. Litterman 1980 has shown how informative priors for autoregressive coeecients can improve economic forecasts. We nd that in seasonal adjustment informative priors can have a m uch greater eeect on our conclusions. In ...
متن کاملConstructing informative Bayesian map priors: A multi-objective optimisation approach applied to indoor occupancy grid mapping
The problem of simultaneous localisation and mapping (SLAM) has been addressed in numerous ways with different approaches aiming to produce faster, more robust solutions that yield consistent maps. This focus, however, has resulted in a number of solutions that perform poorly in challenging real life scenarios. In order to achieve improved performance and map quality this article proposes a nov...
متن کاملBayesian generalized linear mixed modeling of Tuberculosis using informative priors
TB is rated as one of the world's deadliest diseases and South Africa ranks 9th out of the 22 countries with hardest hit of TB. Although many pieces of research have been carried out on this subject, this paper steps further by inculcating past knowledge into the model, using Bayesian approach with informative prior. Bayesian statistics approach is getting popular in data analyses. But, most ap...
