Machine learning of material properties: Predictive and interpretable multilinear models
Problem
Machine learning models predict material properties accurately but lack transparency, limiting scientific insight.
Why it matters
Opaque models hinder trust and scientific understanding in materials design decisions.
What the AI did
Simple linear combinations of nonlinear basis functions were shown to match kernel and neural network accuracy while remaining directly interpretable via their coefficients.
Results
Comparable accuracy to kernel/neural network approaches for bandgap, formation energy, and spin state prediction (no numbers given)
Impact
Evidence supports interpretable linear models matching black-box accuracy on revisited public material datasets.
