Figure 3. Variational Bayesian recognition of visual stimuli:

Upper Left: time series of sensory cues, sampled from the generative model summarized in Figure 2. Note that the discrimination ratio () is approximately similar to that of the natural images (see Figure 2). Upper Right: Subject's posterior belief, as obtained using the inversion of the perceptual model given observed sensory cues (green: cue-outcome association, blue: visual stimulus category; solid line: posterior mean , shaded area: 99% posterior confidence interval, dots: sampled hidden states). Note that on each trial, the category of the visual stimuli was recognized perfectly. Lower Left: scatter plot comparing the simulated (sampled, x-axis) versus perceived (estimated, y-axis) cue-outcome associative strength. Lower right: simulated reaction times.
