  • Data-Driven Training for RNN-Based Prognostics and Health Management in Industrial Machine Toolsopen_in_new

    With the rapid advances of machine learning algorithms and sensing technologies, machine prognostics and health management (PHM) via data-driven approaches has become a trend in sophisticated machine tool industry. Recurrent neural network (RNN) is an important technique to process the sequential sensing data. Two popular PHM approaches are: 1) predicting the remaining useful life (RUL) of a machine, and 2) applying anomaly detection (AD) on a machine. Run-to-failure data is necessary to train RUL-based models. During the process of collecting run-to-failure data, a machine may face the situation of abnormality, such as impulse signals, before it fails. Therefore, AD-based approaches, which aim to detect anomalies in real-time, are more suitable for machine tool industry compared to RUL approaches. However, due to vanishing gradient problem in RNN, it is difficult and time-consuming to train an RNN model. To this end, we propose a framework, called QUAntized Recurrent neural network autoencoder for Time-series anomaly detection (QUART), to accelerate the RNN model training for the abnormality detection. The main idea of QUART is to reduce data size by mapping raw data into finite classes according to the probability mass in the raw data. To learn the anomaly states without considering the sequence order of sensing values in a short interval, we adopt a data shuffling method to increase the variance of the training data. Our experiment results show that the proposed framework can accelerate almost 120 times faster than the existing RNN methods.
