The Essential Complexity of Auditory Receptive Fields
Fig 7
A. Examples of parameterized temporal filters with varying numbers of poles (P) and zeros (Z). Curve at top shows a very simple kernel with only one pole and no zeros (P1Z0). The curves below show more complex kernels requiring more parameters. B. Pareto plot comparing performance of the different pole-zero parameterizations, each for D = 1…5 spectral channels (Gaussian parameterization), plotted as in Fig 4C. The simplest temporal kernel requires more spectral channels to approach the performance of more complex kernels. The D = 3, P3Z1 kernel showed the trend for best performance overall.
