Sentence examples for rare probabilities from inspiring English sources

These risks, and their consequences, however, ultimately became visible when those rare probabilities occurred.

Here we extend the capability of the method to rare probability computation by using the idea of importance sampling (IS).

Even though the rare probability of this accident, it still has got a lot of concerns in the safety analyses of HTR-PM, due to the possible severe consequences of the air ingress accident, which would cause oxidation of the graphite material in the reactor.

Nonetheless, excision of a transposon is estimated to be rare (probability less than 1 × 10−4 transpositions), and the probability of an adverse event is even lower [51], [52].

In that case, some properties can be derived on the partial robustness of classical methods such as FORM, Monte Carlo or response surfaces to estimate rare failure probabilities under the constraint of the number of expensive model runs, such as robust probability bounds, saved number of model runs or guaranteed variance reduction.

We present a framework for performing Bayesian updating of rare event probabilities, termed BUS.

Current PRA methodology uses expert opinion in the assessment of rare event probabilities.

Assessing rare event probabilities still suffers from its computational cost despite some available methods widely accepted by researchers and engineers.

Very efficient sampling algorithms have been proposed to estimate rare event probabilities, such as Importance Sampling or Importance Splitting.

But the expensive computational costs associated with calculations of rare failure probabilities are still a large obstacle in practice.

This strategy relies on Kriging meta-modeling and manages to achieve sharp upper confidence bounds on the rare events probabilities.
