The system and method utilizes computer-based system to annotate historical data locate a prior failure event. Data associated with sensor readings prior to the failure event is annotated to note that it is likely associated with a failure and is compared to normal operating condition data. A fast boxes algorithm is used to learn the location of the pre-event data (positive class, minority group) with respect to the normal operation data (negative class, majority group). An evaluation is performed to analyze the discriminatory strength of the pre-event data with respect to the normal data, and if a relatively strong difference is found, the associated pre-event data is stored and used as a “symptom” to monitor the on-going performance of a machine and predict the possibility of an unexpected failure days before it would otherwise occur.
