In this research, we study an automated feature extraction technique to calculate new features from raw sensor data provided by an elevator data recording system and to create a more generic machine learning model for fault detection. Another data set called maintenance data is used to find the time period for creating class variables. The calculated features attached to
class variables are classified as healthy or faulty using random forest algorithm. The time period starts from a fault reported by the customer and ends when maintenance is finished and reported. We use accuracy, sensitivity and specificity as evaluation parameters for this research.
