Optimization ofWavelet Neural Networks Modelby Setting theWeighted Value of OutputThrough Fuzzy Rules Takagi-Sugeno-Kang (TSK)Type As a Fixed Parameter
2018
In this paper, we propose a model of fuzzy wavelet neural network (FWNN) which
is optimized from wavelet neural network (WNN) model by setting the weighting
coefficient of the output using the TSK fuzzy inference type. This coefficient in the
proposed FWNN model is seen as exogenous parameters that are not updated in the
learning process using the method of gradient descent with momentum. The accuracy
and the execution time of the model was illustrated using several univariate
time series data cases, and the results were compared with models ofWNNthat had
been previously published. The simulation results for variety of these cases show
that the effectiveness and the accuracy of proposed FWNN model is better than the
previous model of WNN.
