Title:
INTELLIGENT MISSING DATA FILLING METHOD, APPARATUS AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/169116
Kind Code:
A1
Abstract:
An intelligent missing data filling method, apparatus and device, and a storage medium, relating to an artificial intelligence technology. The method comprises: receiving a missing data set; performing time mapping processing on the missing data set to obtain an output sequence set and a time mapping relationship; performing data classification on the output sequence set by using a joint Bayesian algorithm to obtain a classification data set; capturing missing data features of the classification data set to obtain a missing data feature set; calculating a feature time relationship of the missing data feature set according to the time mapping relationship; performing multi-time sequence fusion on the feature time relationship to obtain a time point missing data set; and calculating a probability residual value of the time point missing data set, and calculating a data filling value by taking the probability residual value as a function value of a preset data filling function. The method can implement a more accurate missing data filling function.
