1. A computer implemented method executed by one or more computing devices for mining association rules, said method comprising:
sampling, by at least one of the one or more computing devices, a plurality of transactions from a transaction dataset according to a predetermined sampling method; mining, by at least one of the one or more computing devices, the sampled plurality of transactions based at least in part on a minimum support threshold and a minimum confidence threshold, the mining identifying one or more association rules when the minimum support threshold and the minimum confidence threshold are satisfied; determining, by at least one of the one or more computing devices, whether the mining identified at least one association rule; and adjusting, by at least one of the one or more computing devices, the minimum support threshold and the minimum confidence threshold based at least in part on a determination that the mining step did not identify at least one association rule, wherein the adjusting increases the probability that further mining will identify at least one association rule by:
decrementing at least one of the minimum support threshold and the minimum confidence threshold by a first percentage based at least in part on a determination that at least one of the minimum support threshold and the minimum confidence threshold is greater than a first value; anddecrementing at least one of the minimum support threshold and the minimum confidence threshold by a second percentage based at least in part on a determination that at least one of the minimum support threshold and the minimum confidence threshold is less than or equal to the first value and greater than a second value. |
