Table VI Database Characteristics for the Properties of Electrode \(1^a\) and Root Mean Squared Error (rmse) for the Inverse PLS Regression Model

From: Metamodeling of the Electrical Conditions in Submerged Arc Furnaces

Output Database DM
Mean Min Max \({\hbox {rmse}}^b\)
\({{I}}_1\) (kA) 132.3 127 138 0.6
\({{z}}_1\) (m) 1.45 1.1 1.8 0.12
\(\sigma _1\) (S/m) 315 170 460 47
\(\sigma _{\text{Ch}}\) (S/m) 22.5 12.0 33.0 3.3
\({{S}}_1\) 1.5 0.0 3.0 0.4
  1. \(^a\)Thanks to the imposition of the rotational symmetry, the same values are found for Electrode 2 and 3
  2. \(^b\)Relative to the validation data
