Phi fluctuates with surprisal: An empirical pre-study for the synthesis of the free energy principle and integrated information theory
Fig 10
Empirical goal priors (EGPs) of the LODs in the hard task, which reached perfect fitness.
For each perfect animat, 4 EGPs were constructed based on distinguishing first, catch and avoid trials, but also, left and right trials. The top row of blocks represent the avoid EGPs and the bottom row the catch EGPs. Those based on left trials are on the left and those based on the right trials are on the right. Each block consists of 8 heat maps, one for each of the LODs. The heat maps have 33 columns, one for each timestep (minus the first and last), and 4 rows, one for each possible sensory state. The sensory states are denoted by two binary digits, the first representing the left sensor and the second the right sensor (0 = off, 1 = on). Each cell in the heatmap represents the probability of the given sensory state at the given timestep. The color coding is constructed such that white represents a 0.25 probability. As the probability decreases below 0.25 colors become increasingly gray, and as the probability increases above 0.25 colors become increasingly orange. Probabilities with a value of 1 have a dark purple color to indicate states of certainty.
