Abstract: A system and method are provided to facilitate automated data imputation. During operation, the system generates a cluster model based on raw data obtained from sensors with multiple states, wherein the raw data includes missing values. The system replaces the missing values with first imputed data based on the cluster model. The system iterates, until a predetermined threshold has been reached, through a series of operations which include: updating the cluster model based on most recently imputed data; predicting outliers based on the cluster model; marking the outliers as null values to obtain filtered data; updating the cluster model based on the filtered data; and replacing the null values with second imputed data based on the cluster model.
