Normalized feature importance for each cosmological parameter. Graph statistics have a fundamental importance for the measurement of Ω_M and Ω_Λ, as do the MFs for n_s, and the HOM for σ₈, while w₀ slightly favors HOM and MFs. Overall the information measured from the different estimators increases with decreasing redshift. From left to right, the R² scores are {0.03, −, 0.70, 0.70, 0.81, 0.32, 0.80}, as reported in Table 4.
