Oscillator heterogeneity can enhance correlated noise-induced synchronization at low input correlations. (A) Two PRCs with the form Δ_j(θ_j) = sin(a_j) − sin(a_j + θ_j) + b_j sin(2θ_j), a₁ = 0.1, b₁ = 0.32, a₂ = 0.6, and b₆ = 0.3. (B) R(ϕ) with different combinations of PRCs. Blue: PRC 2-PRC 2; red: PRC 1-PRC 2; green: PRC 1-PRC 1. Solid lines are theoretical predictions from the solution to the BVP and open symbols are Monte Carlo simulation results (same notation applies in following figures). Parameters used: τ = 1 and c = 0.8. (C) Synchronization as input correlation varies from 0 to 1; inset shows magnification when c < 0.5. (D) Same as (C), but using the ML model. Parameters used: I₁ = 110, ϕ₁ = 0.04616, I₂ = 120, and ϕ₂ = 0.04.
