Model for mbj_bandgap¶
- Description: This is a benchmark to evaluate how accurately an AI model can classify a material as a semiconductor/insulator vs. metal based on the band gap computed with the TBmBJ meta-GGA density functional using the JARVIS-DFT (dft_3d) dataset. The dataset contains different types of chemical formula and atomic structures. Here we use accuracy of classification (ACC) to compare models with respect to DFT accuracy.
