| abstract |
The present invention provides an abnormal sound detection learning technology that is able to generate a feature-quantity extraction function for detection of abnormal sound, irrespective of the availability of abnormal sound learning data. The abnormal sound detection learning device comprises: a first function updating unit 3 which updates, on the basis of an optimized index of a variational autoencoder, a feature-quantity inverse transformation function and a feature-quantity extraction function which have been inputted; an acoustic feature-quantity extraction unit 4 which extracts an acoustic feature quantity of normal sound on the basis of normal sound learning data; a normal sound model updating unit 5 which updates a normal sound model using the extracted acoustic feature quantity; a threshold updating unit 6 which calculates a threshold value φ ρ corresponding to a false positive rate ρ, which is a specific value, using the normal sound learning data and the inputted feature-quantity extraction function; and a second function updating unit 8 which updates the updated feature-quantity extraction function on the basis of a Neyman-Pearson-type optimization index determined by the calculated threshold φ ρ , wherein the processes performed by the respective units are repeated. |
