Performance comparison of the proposed combined loss MLP model with other machine learning models for secondary property predictions.

	Validation set RRMSE (%)			Test set RRMSE (%)
	$S_{\mathit{Sw}}$	$V_{\mathit{Th}}$	${\mu }_{\mathit{Deg}}$	$S_{\mathit{Sw}}$	$V_{\mathit{Th}}$	${\mu }_{\mathit{Deg}}$
Linear	60.5	14.2	5.9	68.9	14.7	6.3
SVM	74.5	41.5	7.8	80.0	39.9	8.0
Random forest	32.9	23.7	4.9	37.2	24.2	5.2
MLP	8.8	11.7	2.4	8.2	11.9	2.5
Combined loss MLP	5.3	6.7	1.8	5.7	3.6	1.3

The RRMSE metric is used for the evaluation.
