Random forest classification based acoustic event detection utilizing contextual-information and bottleneck features
作者:
Highlights:
• A random forest classification based acoustic event detection system was constructed as the baseline system.
• Contextual information was employed to cope with the acoustic signals with long duration.
• Global bottleneck features were employed in the acoustic event detection system to utilize the prior knowledge of the event category information.
• Category-specific bottleneck features were employed in the acoustic event detection system to utilize the prior knowledge of the event boundary information.
• Evaluations on the UPC-TALP and ITC-IRST databases of highly.
