(a) The entropy production rate (EPR) versus parameter b. The decision time represented by the MFPT versus parameter b shown with the red line. (b) The total energy cost versus parameter b. (c) With speed emphasis, less energy is required, but the performance is worse. Here the accuracy is represented by the ratio of the probability of the path of the correct choice to the error one. (d)–(f) The inter-relationship among the speed, accuracy, and energy cost based on the varying input threshold. In all subgraphs, parameters a = 269.5, μ0 = 10 Hz, c′ = 0.24, and D = 1.6 × 10−7. |
