Supplementary Explanation on Accuracy

Temperature-dependent property is a function of temperature, so it does not have a constant value as for a constant property. Therefore, it is difficult to clearly set an absolute criterion such as %. This means that the evaluation on the performance of property prediction can differ depending on what criteria and what range of temperature are selected for evaluation. Finally, 5 types of evaluation criteria were selected to classify into 5-phased Accuracy Level, like using % absolute error of experimental-forecast values, the average absolute error for experimental-forecast values, the sum of those values, the difference in the area of property values with the temperature range as base, etc.
