Time Series Classification with Multiple Wavelength Scattering Signals for Nuisance Alarm Mitigation
Publikováno v:
Fire, Vol 7, Iss 1, p 14 (2023)
Smoke detectors are the most widely used fire detectors due to their high sensitivity. However, they have persistently faced issues with false alarms, known as nuisance alarms, as they cannot distinguish smoke particles, and their responsiveness vari
