Adaptive Noise Reduction for Sound Event Detection Using Subband-Weighted NMF †
Sound event detection in real-world environments suffers from the interference of non-stationary and time-varying noise. This paper presents an adaptive noise reduction method for sound event detection based on non-negative matrix factorization (NMF). First, a scheme for noise dictionary learning fr...
