1. Simulation results with a bimodal basis function.
Simulation results with a bimodal basis function. A, Depiction of eight channel basis functions, each one with two peaks positioned ∼67° apart. To facilitate visualization, the center channel (cyan) is plotted in a thicker line. The channels are obtained by multiplying the original channels (Fig. 1) with a matrix that transforms the unimodal to a bimodal shape. B, Channel response functions derived by the inverted encoding model at high noise (left panel) and low noise (right panel) levels. C, Posterior probability of the stimulus derived by the Bayesian approach at high noise (left panel) and low noise (right panel) levels.
