Theory of Acceleration of Decision-Making by Correlated Time Sequences

Figure 7

Correct decision rate at t = 1000 derived by the proposed theoretical model (red) and numerical simulations (blue) as a function of the autocorrelation coefficient λ. The reward probability settings and number of threshold levels are the same as in Figure 2. The threshold level is specified by N = 2 in (a)–(c), whereas N = 4 in (d)–(f). The reward probability in (a) and (d); (b) and (e); and (c) and (f) is given by (PA, PB) = (0.9, 0.3); (PA, PB) = (0.6, 0.5); and (PA, PB) = (0.9, 0.7), respectively.
