Structural complexities of knowledge-guided symbolic regression models for melt conveying in single-screw extruders

Dataset

Description

Excel spreadsheet with numeric values and textual description.

Contains the expression tree lengths and depths of symbolic regression models for the dimensionless melt flow rate in single-screw extruders with different cases of integrated domain knowledge:

- Case 1: theory of similarity only,
- Case 2: additional derived input features for pure pressure flow,
- Case 3: logarithmic scaling of the dimensionless flow rate with channel aspect ratio as derived input feature,
- Case 4: theoretical approximation equation for superimposed drag and pressure flow in dimensionless space.
