IHF: Industrial High Frequency Operation Queue Discovery Algorithm

When using traditional PrefixSpan algorithm to complete industrial Internet high-frequency operation sequence mining tasks, there are problems such as low efficiency and disordered output results. Based on the PrefixSpan algorithm, we propose an IHF algorithm (Industrial High Frequency operation queue discovery algorithm) suitable for mining high-frequency operation sequences of the Industrial Internet. The algorithm reduces the scanning operation of the database by measuring the sequence length in the system, and reduces the generation of candidate sequences by constraining the sequence projection. The accuracy and performance of the IMF algorithm are verified through experiments.
