Risk analysis may be defined as the problem of estimating the probabilities of rare events and the magnitudes of associated damages. The topic unifies the environmental sciences. This paper considers risk analyses for earthquakes, wildfires and floods. The computation of insurance premiums is used to motivate and unite the work.

Classifiers that aim at doing credible predictions should rely on carefully elicited prior knowledge. Often this is not available so they should start learning from data in condition of near-ignorance. This paper shows empirically, on an agricultural data set, that established methods of classification do not always adhere to this principle. Traditional ways to represent prior ignorance are sho...
