Method for imputing missed data in sensor data sequence with missing data

A computer program product comprising computer executable program code recorded on a computer readable non-transitory storage medium where the computer executable program code when executed causing the actions which include:

• generating the sensor data sequence over a period of time to determine behavior of a system over the period of time;
• identifying an instance of time instant associated with a missing sensor data value associated with the sensor data sequence;
• identifying a similar response data sequence corresponding to the sensor data sequence with the missing sensor data value, wherein the similar response data sequence is identified based on highest correlation with the sensor data sequence with the missing sensor data value;
• identifying a data value at an instance of time instant associated with the similar response data sequence corresponding to the instance of time instant associated with the missing sensor data value associated with the sensor data sequence;
• determining nearest neighbors of the identified data value in the similar response data sequence, by searching neighbors within a predetermined nearness threshold;
• determining instances of time instants of the determined nearest neighbors in the similar response data sequence;
• identifying instances of time instants in sensor data sequence with the missing sensor data value corresponding to the instances of time instants of the determined nearest neighbors in the similar response data sequence;
• determining a candidate value for imputing, based on sensor data values of the identified instances of time instants in the sensor data sequence through learning based on semantics of features of the sensor data values in the sensor data sequence;
• imputing the candidate value, in the instance of time instant associated with the missing sensor data value associated with the sensor data sequence using the sensor data values of the identified instances of time instants in the sensor data sequence;
• determining the behavior of the system using the sensor data sequence with imputed candidate value.
