Description
  • The application provides a data association method based on multi-source heterogeneous power data, which aims to solve the problem that power data represent different data sources; extracting attributes of each item of data in each data source through feature engineering; respectively mapping the characteristic vectors of the attributes of each item of data in the anchor point data source to a discrete subspace through quantification, and generating a reverse arrangement table of a representative vector and the discrete subspace corresponding to the attributes of each item of data; matching the characteristic vectors corresponding to the attributes of each item of data in the data source to be matched with the representative vectors corresponding to the attributes of each item of data in the anchor data source; and respectively calculating the similarity scores of the data to be fused with the same attribute in the data source to be matched through an attribute similarity measurement formula. The method can carry out feature vectorization processing on data in a plurality of different dimensional data sources, and improve the accuracy of the data by using a smooth weighted Jaccard (Jaccard) algorithm.
