Optimal transport analysis reveals trajectories in steady-state systems

Fig 7

Non-conservative simulation.

(a) Illustration of potential-driven (Ψ) and non-conservative (f) components of the overall drift v. (b) Examples of simulated particle trajectories following the drift-diffusion process. (c) Snapshot samples shown in the first two dimensions of , with source (R > 0) and sink (R < 0) regions indicated. (d) Comparison of fate probabilities towards the sinks in the first quadrant. (e). Correlation of estimated fate probabilities to ground truth fates with (λ = 0.25) and without incorporation of velocity data (λ = 0). (f) Summary of fate probability correlation as a function of λ ∈ [0, 1].
