Expectation to hydrologists on groundwater

Ecohydrology--why hydrologists should care.

A 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.

Improving on Expectation Propagation

A series of corrections is developed for the fixed points of Expectation Propagation (EP), which is one of the most popular methods for approximate probabilistic inference. These corrections can lead to improvements of the inference approximation or serve as a sanity check, indicating when EP yields unrealiable results.

On Gaussian Expectation Propagation

In this short note we will re-derive the Gaussian expectation propagation (Gaussian EP) algorithm as presented in Minka (2001) and demonstrate an application of Gaussian EP to approximate multi-dimensional truncated Gaussians. 1 On Gaussian Distributions Here we will summarise some important equalities about the Gaussian density. A Gaussian density in Rn is defined by N (x;μ,6) := (2π)− 2 |6|− ...

Infectious Disease Research—What Role Is There for Hydrologists?

Numerous virulent and widespread diseases are related to water. The transmission and outbreak of water-related diseases are closely coupled to their hydrological environment. Changes in this environment and the associated hydrological processes may affect the occurrence and virulence of waterrelated diseases. Environmental changes can be manifold, including e.g. climate and land use, agricultur...
