Fig. 3: Training compositions for three levels of tessellation (T1, T2 and T4).
From: Electronic structure prediction of medium and high entropy alloys across composition space
The red dots show training compositions. The top row shows compositions for the ternary (SiGeSn) system and the bottom row shows compositions for the quaternary (CrFeCoNi) system. Note that we train the model T4 with the 4th iteration of tessellation, because the training compositions in the third iteration exclude available training compositions from the second iteration. The star depicts an additional point considered in the quaternary T2 model to capture information in the center, approximating the octahedron in the second tessellation of the tetrahedron.
