In this talk, we show that the available information about unknown parameters in rare events data is only tied to the relatively small number of cases, which justifies the usage of negative sampling. ...

We are interested in estimating probabilities of rare events in the context of com-
puter experiments. These rare events depend on the output of a physical model with
random input variables. Since t...
