The invention relates to a data screening method and device, equipment, a storage medium and a program product, and the method comprises the steps: carrying out the rule matching according to a rule set corresponding to to-be-processed data and a preset rule management table, and generating a rule hit table; the rule set comprises at least one combination rule, the rule management table comprises indexes of sub-rules in all the combination rules, then determining a rule association table corresponding to the rule set according to the rule management table, and screening the to-be-processed data according to the rule hit table and the rule association table to obtain a screening result. According to the method, the rule relation between the combination rule and the sub-rules in the combination rule is maintained through the rule management table, the rule matching condition of the to-be-processed data is analyzed through the rule hit table and the rule association table, the matching effect of block rules can be achieved, and then the data screening efficiency is improved. In addition, according to the method, a plurality of sub-rules can be combined at will, and the purpose of more accurate data screening can be achieved.

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.

The invention provides a rule generation method, a fault prediction method and a related device, and relates to the technical field of data processing. The rule generation method can comprise the steps of obtaining a target sample; wherein the target sample comprises a positive sample and a negative sample, the positive sample refers to a sample with a target fault, and the negative sample refers to a sample without a fault; according to an output time sequence, searching at least one positive rule of which the occurrence frequency is greater than a frequency threshold value in the positive sample, and searching at least one negative rule of which the occurrence frequency is greater than the frequency threshold value in the negative sample; and obtaining a combined rule for fault prediction based on the positive rule and the negative rule. According to the technical scheme provided by the invention, the problems of limited coverage range and low accuracy of artificially defined fault prediction rules in the prior art can be solved.
