Shapley values of two random test projections (upper and lower panel) from the merged and stacked MDPL2 and Virgo ΛCDM data. Left panel: Standard deviation of the halo velocity in each pixel. Right panel: Shapley values in each pixel (pink: higher prediction; blue: lower prediction). The red circle represents the R₂₀₀, while the black and purple circles represent the true and the predicted R_ta, respectively. Lower dispersion is always prominent in the central area due to the virialization of the matter surrounding the central perturbation. However, the extent of this lower dispersion area seems to indicate to the model where the turnaround radius should be. In particular, in the first image, the structure seems to have higher dispersion in areas far from the center, compared to the second one, which has lower values. The high dispersion seems to indicate to the model that the turnaround radius should be lower, while the lower dispersion indicates the opposite.
