Researchers have discovered significant redundancy within electronic structure datasets used for machine learning in materials science. They found that the underlying data possesses low intrinsic dimensionality, meaning much of the information is repetitive. This suggests that dataset sizes can be drastically reduced, potentially by orders of magnitude, without compromising predictive accuracy or chemical accuracy, thereby speeding up training times. AI
