Nonnegative Matrix Factorization Based Adaptive Noise Sensing over Wireless Sensor Networks
An adaptive noise sensing method is proposed to improve the speech sensing performance of speech-based applications operated over wireless sensor networks. The proposed method is based on nonnegative matrix factorization (NMF), which consists of adaptive noise sensing and noise reduction. In other w...
