Abstract: A nonlinear personalized model is established to predict individual head-related transfer function (HRTF). Principal component analysis (PCA) is applied to obtain individual weights as the outputs of the model. Some important anthropometric parameters are selected according to the Laplacian score and correlation analyses between all measured parameters and the individual weights. They act as the inputs to the model. Constructing a radial basis function (RBF) neural network to learn the nonlinear model, the individual HRTF can be predicted according to the measured anthropometric parameters. Simulation results show that the proposed method outperforms the partial least squares regression (PLSR) method in predicting individual HRTF.
