摘要
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for risk detection. One exemplary method may comprise: obtaining a first subset of a plurality of risk-detection rules, the first subset being associated with a first coverage score; constructing, based on the first subset, a lower-bound data mapping that outputs an approximate coverage score for an input subset; and constructing, based on the first subset, an upper-bound data mapping comprising a set of parameters; and generating a third subset of the plurality of risk-detection rules; and in response to the first coverage score exceeding the third coverage score, selecting rules in the first subset for risk-detection on a new transaction.
