Abstract

The embodiment of the invention discloses a data repairing method and adevice. The method comprises the following steps: firstly, acquiring a first abnormal data vector set with at least one abnormaldata; further acquiring a set of z first reference data vectors having vectors of the same type as the set of first abnormal data vectors; then determining an abnormal data bit corresponding to each abnormal data in the first abnormal data vector set; repairing the first set of abnormal data vectors based on the z sets of first reference data vectors according to the determined abnormal data bits.

Description

technical field [0001] The invention relates to the technical field of big data analysis, in particular to a data restoration method and device. Background technique [0002] At present, all major data service platforms focus on data collection, data mining, data application and data sharing, and launch products and services in many fields including environmental protection, safety, health and so on. Taking the big data support and application services related to the vehicle network as an example, because the accuracy of data collection is affected by many factors, data abnormalities occur from time to time. In related technologies, in order to realize the restoration of abnormal data, a linear interpolation method or a data point smoothing processing algorithm is usually used. [0003] However, the data repair algorithm in the related art has the following obvious defects: 1) the algorithm is not mature enough, and the repair accuracy is low; 2) the algorithm execution tim...
