    • A system and method for predicting failures of machinery such as a gas turbine. 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.
    • 一种用于预测诸如燃气轮机的机器故障的系统和方法。 该系统和方法利用基于计算机的系统来标注定位先前故障事件的历史数据。 与故障事件之前的传感器读数相关联的数据被注释以指出它可能与故障相关并且与正常操作条件数据相比较。 使用快速盒子算法来学习正常操作数据(负类别,多数组)的事件前数据(正类,少数群)的位置。 进行评估以分析事件前数据相对于正常数据的判别强度,并且如果发现相对较强的差异,则将相关联的事件前数据存储并用作症状以监视正在进行的 机器的性能,并预测在发生其他情况发生之前几天发生意外故障的可能性。
