Publication number: 20210271957Abstract: The invention relates to a technology for detecting an abnormal signal using a filter for removing normal sound (or normal signals) around a sensor at normal times. The filter is provided to remove normal sound based on a denoising autoencoder learning technique for removing noise and used to determine whether field sound is an abnormal signal different from that of normal times. The filter is trained to pass normal sound, regarded as noise, to output a value of 0 and pass an abnormal signal without change. The filter is retrained by collecting only normal sound rather than abnormal signals in the field and then adding the collected normal sound to the existing training data. Therefore, even machine-learning nonexperts may easily and conveniently retrain the filter.Type: ApplicationFiled: February 11, 2021Publication date: September 2, 2021Applicant: Electronics and Telecommunications Research InstituteInventors: Gi Young LEE, Byung Bog LEE, Woong Shik YOU, Cheol Sig PYO
