METHOD FOR ANALYZING TIME SERIES DATA DETERMINING A KEY INFLUENCE VARIABLE AND APPARATUS SUPPORTING THE SAME

摘要

Provided is a method of determining a key influence variable for a target class among a plurality of time series variables. The method of determining a key influence variable comprises the following steps of: acquiring a first matrix predicted as the target class from multiple time series data related to the time series variables; acquiring a second matrix belonging to a specific class; calculating similarity between the two matrixes except a value of a first time series variable from the first matrix and the second matrix; and determining the first time series variable as the key influence variable in response to determination that the calculated similarity satisfies a predetermined condition, wherein a first row or a first column of the first matrix may be formed of a measured value of the first time series variable and a second row or a second column of the first matrix may be formed of a measured value of a second time series variable.
