Confusion matrix for the NN multi-classification performance and its errors. In this case, we show the distinction between three classes: ΛCDM and CDE through the activation of couplings in β₁ (low-redshift coupling at z <  100) and in β₂ + β₃ (high-redshift coupling at z >  100)As a reminder, the tomographic bins for each coupling parameter are z (β₁)< 100, 100 <  z (β₂)< 1000, and z (β₃)> 1000.
