- Anomaly detection
Audio abnormaly detection
Realize early detection of equipment abnormalies based on signs of degradation in operating sound.
- Using an original Variational AutoEncoder method, it became possible to detect even faint sounds of deterioration without being affected by unknown noise.
- Aiming for applications in the diagnosis of degradation in infrastructure facilities
Applications
- Degradation diagnosis for equipment and facilities
- Audio testing at manufacturing sites
Benchmarks, strengths, and track record
- Accurately infer the degree of equipment degradation (Correlation coefficient: 0.99) even using audio signals overlaid with unknown noise. (Acoustical Society of Japan 2019 Autumn Meeting)
