Fig 8. Transition rates inferred from tracked zebrafish data for the model with three kinematic variables.

Transition types are indicated in column headings. For each transition type, λ(s → s′), from state s to s′, the rates are shown by color intensity (colorbar on top), as a function of mutual distance u³ (horizontal axis), velocity magnitude u¹ (vertical axis) and wall distance u² (three rows, see legends at left). We used bin centers {1, 3, 5, 7} for the velocity magnitude u¹, bin centers {−3, −1, 1, 3} for the mutual distance u³ and the wall distance is split to three bins: u² ∈ [−2, 0), [0, 2], and |u²| > 2. The rates were inferred jointly from two experiments, each with two fish; the rates were assumed to be the same for all the fish.
