  • Systems and methods for generating a synthetic dataset from road vehicle positioning data
    Patent number: 12639473
    Abstract: Generating a synthetic dataset from road vehicle positioning data. The method involves iteratively selecting a seed record and determining a set of candidate partner records based on matching bigrams between the selected seed record and potential partner records. The method further includes determining subsequences for the candidate partner records and selected seed record based on locations of the matching bigrams. A candidate partner record is selected based on whether a length difference, in terms of time, distance, or number of road events, between the subsequences is less than a defined threshold. The subsequence of the selected seed record is replaced with the subsequence of the selected candidate partner record to produce a mutated seed record. The mutated seed records to produce a synthetic dataset.
