Publication number: 20240152133Abstract: A threshold acquisition apparatus acquires a threshold for determining whether an anomaly score acquired from a target sound is normal or anomalous. The threshold acquisition apparatus includes: an allowable number setting unit that sets an allowable number of times such that the number of anomaly scores determined to be anomalous included in a set of anomaly scores per predetermined section length, which is a part of time-series acoustic signals that do not include an anomalous sound, does not exceed the allowable number of times; and a threshold estimation unit that estimates a threshold candidate such that the number of sections determined to be anomalous per predetermined section length, which is a part of time-series acoustic signals, satisfies a predetermined criterion by using the allowable number of times, and acquires the threshold candidate as the threshold.Type: ApplicationFiled: October 16, 2019Publication date: May 9, 2024Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Shin MURATA, Yuma KOIZUMI, Noboru HARADA, Shoichiro SAITO
