The predicted median with associated upper and lower uncertainties vs. the measured values for 60 δ Sct stars (top row), fractional errors (middle row), and distribution of fractional error (bottom row) obtained by ensemble ML for ν(A_max) (left panel), ν_max (middle panel), and Δν (right panel; see supplementary electronic table hosted by Figure 1). The red dashed line (y = x) shows the ideal prediction line in the top row, whereas the black dashed line marks the zero fractional error reference in the bottom row.
