Expectation propagation as a way of life∗
We revisit expectation propagation (EP) as a prototype for scalable algorithms that partition big datasets into many parts and analyze each part in parallel to perform inference of shared parameters. The algorithm should be particularly efficient for hierarchical models, for which the EP algorithm works on the shared parameters (hyperparameters) of the model. The central idea of EP is to work a...

abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
15 صفحه اولsecuritization of mortality risks in life annuities
insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...
15 صفحه اولCoronary heart disease and future expectation of life.
SUMMARY Mortality from coronary heart disease (CHD) has risen enormously over the last generation. Some regard the concomitant increase in life expectancy as the sole explanation; others maintain the increases at least in part to be real. Irrespective of the true causes, the question arises: If increases in CHD mortality continue in certain of the populations most affected, may not expectation ...
متن کاملA Study on Preference Orderings of Mathematical expectation, Expected Utility and Distorted Expectation
One of the challenges for decision-makers in insurance and finance is choosing the appropriate criteria for making decisions. Mathematical expectation, expected utility, and distorted expectation are the three most common measures in this area. In this article, we study these three criteria, and by providing some examples, we review and compare the decisions made by each measure.
