Abstract: A computer-implemented method for monitoring computing system status by implementing a deep unsupervised binary coding network includes receiving (41) multivariate time series data from one or more sensors associated with a system, implementing (420) a long short-term memory (LSTM) encoder-decoder framework to capture temporal information of different time steps within the multivariate time series data and perform binary coding, the LSTM encoder-decoder framework including a temporal encoding mechanism, a clustering loss and an adversarial loss, computing (430) a minimal distance from the binary code to historical data, and obtaining (440) a status determination of the system based on a similar pattern analysis using the minimal distance.
