Metrics for quantifying isotropy in high dimensional unsupervised clustering tasks in a materials context

no code implementations25 May 2023 Samantha Durdy, Michael W. Gaultois, Vladimir Gusev, Danushka Bollegala, Matthew J. Rosseinsky

Using fractional anisotropy, a common method used in medical imaging for comparison, we then expand these measures to examine the average isotropy of a set of clusters.

We also find that the radial basis function improves the linear separability of chemical datasets in all 10 datasets tested and provide a framework for the application of this function in the LOCO-CV process to improve the outcome of LOCO-CV measurements regardless of machine learning algorithm, choice of metric, and choice of compound representation.

In addition, due to the chemical expertise involved in the parameter-tuning, these approaches can be {\em biased} towards previously-known crystal structures.
