title = "Efficiency evaluation and orthogonal basis determination in functional HRTF modeling",
abstract = "This paper consider the problem of how to evaluate the efficiency of a 3D continuous functional HRTF model in representing measured data. The proposed method is based on Karhunen-Lo{\`e}ve theorem. After investigating the optimization problem of representing the process with an finite linear combination of orthogonal functions in L2 space by means of the least squared method, the variance of random variables involved in the model is found the key metric in efficiency evaluation of a given functional model. Then, the coefficients of the 3D continuous HRTF model are analyzed. The results show that the efficiency of the model in spatial component expansion is around 70\% and the best choice in frequency component expansion is the spherical Bessel function.",
