Some New Developments in Small Area Estimation
Small area estimation has received a lot of attention in recent years due to growing demand for reliable small area statistics. Traditional area-specific estimators may not provide adequate precision because sample sizes in small areas are seldom large enough. This makes it necessary to employ indirect estimators based on linking models. Basic area level and unit level models have been extensiv...
متن کاملFuzziness in Decision-theoretic Planning
Imperfect knowledge of the world is one of the main issues AI systems have to deal with. In recent years there has been much interest in coping with such imperfections in planning systems. However, most works only emphasize one side of the problem, namely uncertainty. We argue that vagueness (or imprecision) is a fundamental issue which planning systems should also take into account. With this ...
متن کاملScaling Decision Theoretic Planning
As classical planning branches out to consider richer models, many extensions approach decision theoretic models. Decision theory research uses models like MDPs and POMDPs which are very expressive, but can be difficult to scale. Whereas, planning research concentrates quite a bit on scalability. Our previous work and future doctoral thesis concentrates on extending the planning model toward pr...
متن کاملDecision-theoretic Defaults
This paper considers defaults as summaries of decision-theoretic deliberations. We investigate the idea that the default e ! a means that a is the optimal action based on all we know (contingently) being e. It is shown how this notion of a default is nonmonotonic and has a preference for more speciic defaults. It has the advantage of defaults can, in principle, be derived from lower level conce...
متن کاملNoise Variance Estimation in Images
Figure 3: The distribution of the estimated noise in an image (Lenna) to which noise with a uniform shaped distribution is added. Also shown are the true noise distribution and the theoretically estimated distribution. The latter is obtained by convolving the (truncated) uniform function with a normal function.
