Description

technical field [0001] The invention relates to a wavelet neural network processor, in particular to a wavelet neural network processor based on SOPC. Background technique [0002] Wavelet Neural Network (WNN) is the product of the combination of wavelet analysis theory and neural network theory. Pati and Krishaprasad proposed the discrete affine wavelet network model. The basic idea is to introduce the discrete wavelet transform into the neural network model, and then construct the wavelet neural network through the affine frame in the translation and expansion of the Sigmoid function. Zhang Qinghua et al. formally proposed the concept of wavelet neural network in 1992. The idea is to replace neurons with wavelet elements, that is, replace the Sigmoid function with the positioned wavelet function as the activation function, and establish the relationship between wavelet transformation and network coefficients through affine transformation. Connection. [0003] In the spec...
