摘要
An abnormal sound diagnosis device is provided with: a trajectory feature extraction unit (5) for extracting a trajectory vector (15) by converting, into a vector, a trajectory that indicates an intensity feature of an intensity time series (14) in an entire time direction obtained by an intensity time series obtaining unit (4); a discrimination parameter storage unit (6) for storing a discrimination parameter (16) learned with the vector which is the trajectory indicating the intensity feature in the entire time direction of the intensity time series of sound data generated from a reference device as an input and with information indicating a status type of a diagnosis target device as an output; a discrimination unit (7) for obtaining a K-dimensional score vector (17) with respect to each status type of the diagnosis target device from the trajectory vector (15) and the discrimination parameter (16); and a determination unit (8) for determining, by referring to the K-dimensional score vector (17), whether sound generated in the diagnosis target device is normal or abnormal and determining the kind of the abnormality.
