The application discloses a combination rule generation method and device,
electronic equipment and a storage medium. The method comprises the following steps: determining a plurality of original rules according to a
training set of a current service, wherein the
training set comprises a plurality of non-target training samples and a plurality of target training samples; for each original rule, determining an associated rule corresponding to the original rule according to a target training sample that cannot be recognized by the original rule in the plurality of non-target training samples and the plurality of target training samples; determining a target associated rule from the associated rules corresponding to the plurality of original rules; if an iteration termination condition is not met, taking the target associated rule as a new original rule and returning to execute the second step; and if the iteration termination condition is met, tracing each target associated rule to determine a target combination rule. The scheme can generate a combination rule with
high coverage and high accuracy.
