A Novel Scheme of Speech Enhancement Based on Quantum Neural Network
Fei Li, Guobiao Xu · 2009
Quantum neural network (QNN) gives us some advantages unattainable by classical artificial neural network. A model of quantum neuron composed of quantum gates is described. A model of quantum back propagation neural network (QBPNN) based on the quantum neuron and its training algorithm is investigated. A novel approach toward speech enhancement which adopts QBPNN is proposed. For comparison, evaluations were also done for classical NN and other methods. The experiments results show that the scheme of speech enhancement based on QBPNN has better denoising effect and robustness than the traditional methods.
