METHOD FOR ACQUIRING CONSECUTIVE MISSING VALUES, DATA ANALYSIS DEVICE, TERMINAL, AND STORAGE MEDIUM

摘要

The present invention discloses a method for acquiring consecutive missing values, a data analysis device, a data analysis terminal, and a computer-readable storage medium. The method for acquiring consecutive missing values comprises: if it is detected that a target time sequence acquired on the basis of a preset time interval has consecutive missing values, acquiring, according to the preset time interval, all of sequence feature values from all of time sequence samples, so as to generate a feature data sequence of each time sequence sample; performing anomaly detection calculation on each feature data sequence, so as to determine normal data sequences among all of the feature data sequences; acquiring a corresponding target time point of the consecutive missing values in the target data sequence, and acquiring sequence feature values at all of the target time points in all of the normal data sequences; and calculating a mean value of all of the sequence feature values at the target time points, and using feature mean values as filling reference values of the consecutive missing values corresponding to the target time point. The present invention improves the authenticity of data of a time sequence.
