@inproceedings{BarrosoLuque2021SparseEO, title={Sparse Expansions of Multicomponent Oxide Configuration Energy Using Coherency\&Redundancy}, author={Luis Barroso-Luque and Julia H. Yang and Gerbrand Ceder}, year={2021} }

Compressed sensing has become a widely accepted paradigm to construct high dimensional cluster expansion models used for statistical mechanical studies of atomic configuration in complex multicomponent crystalline materials. However, strict sampling requirements necessary to obtain minimal coherence measurements for compressed sensing to guarantee accurate estimation of model parameters are difficult and in some cases impossible to satisfy due to the inability of physical systems to access… Expand
