Prediction of Crystalline Solids from Composition and Crystal Structure
properties of compounds has received considerable attention across different
disciplines and has seen applications in diverse areas. The approach proposed
in this paper is influenced by the advances in Group Contribution Methods
key characteristic of GCMs in general is that the property descriptors (i.e.,
predictors) are explicitly represented by the molecular structure (and chemical
composition) of a compound. One can pose an optimal inverse (design) problem, which attempts to obtain the original
molecule (structure and composition) given a target property value. This is the
main goal of the research area called Computer-Aided Molecular/Mixture Design
(CAMD) as exemplified by several works in the literature (Eljack et al., 2007;
Samudra and Sahinidis, 2013).
the crystalline solids literature, several research groups have proposed
statistical (machine learning) approaches for property prediction. Saad et al.
(2012) investigated both unsupervised and supervised machine learning
techniques to predict structure and properties of crystals with chemical
formula AB. Ma et al. (2015) developed a machine-learning-augmented model based
on artificial neural networks (ANNs) that captures nonlinear
propose using kernel regression (Li and Racine, 2007) as a data-driven and
rigorous nonparametric statistical technique to predict properties of atomic
crystals. A key feature of the proposed approach is the possibility of treating
predictors not only as continuous, but also as categorical data. The latter
specifically allows the predictive model to capture the discrete nature of
crystals with regards to composition (number of atoms in the chemical formula)
and spatial configuration (finite number of crystallographic space groups).
Another important aspect of using kernel regression is the direct access to its
explicit mathematical form, which can be directly embedded in optimal inverse
problems to design new crystalline materials with given target properties. The
property prediction approach is illustrated by training models to predict
electronic properties of 746 binary metal oxides and elastic properties of
1,173 crystals. As a first approach to solving the inverse problem, we describe
an exhaustive enumeration algorithm (Calfa and Kitchin, 2016).
