Understanding Auditory Spectro-Temporal Receptive Fields and Their Changes with Input Statistics by Efficient Coding Principles

Figure 5

Adaptation of gain and spectral filter kernel SRF to input correlations under high/low SNR.

Same input ensemble as that in Figure 3A, except that the smoothing parameter, and , are set for short and long range correlations, respectively. Analogous figure format as in Figure 4, with added illustrations of the adaptation to input correlations. The thick and thin curves correspond to quantities for inputs with large and small correlations respectively, blue/red curves plot signal power and gain respectively.
