Abstract(in Japanese) (See Japanese page)
Abstract(in English) Low-cost sound monitoring is required for maintaining machinery. We aim to reduce the cost of monitoring by reducing the sampling rate, i.e., sub-Nyquist sampling. Monitoring based on sub-Nyquist sampling requires two sub-systems; a sub-system on-site for sampling machinery sound at a low rate, and a sub-system off-site for detecting anomalies from the subsampled signal. In this paper, to achieve both subsystems, we apply non-uniform sampling methods and propose an anomaly detection method based on a demultiplexer and an end-to-end LSTM autoencoder.
