Phase-Mapper: An AI Platform to Accelerate High Throughput Materials Discovery

Abstract: High-Throughput materials discovery involves the rapid synthesis, measurement, and characterization of many different but structurally-related materials. A key problem in materials discovery, the phase map identification problem, involves the determination of the crystal phase diagram from the materials composition and structural characterization data. We present Phase-Mapper, a novel AI platform to solve the phase map identification problem that allows humans to interact with both the data and products of AI … Show more

“…The unified COS, PCC, and JSD measure dissimilarity between vectors from cosine metric, linear correlation, and information entropy perspectives, respectively, and are not involved with physical meanings. In our future work, clustering techniques through injecting physical information into machine learning methods, like Gibb's phase rule imposed in AgileFD, 21 are more desirable due to their better interpretability.…”

“…And successfully applied unsupervised learning methods are primarily based on non-negative matrix factorization (NMF) and hierarchy clustering analysis (HCA). CombiFD 20 and AgileFD 21 were both developed on the basis of NMF and performed well in grouping XRD patterns, 22 and the latter carried sufficient physical significance by incorporating Gibbs's phase rule. As for HCA, it produces dramatic outcomes with different dissimilarity measures.…”

“…For a comprehensive description of the mathematics of AgileFD, we refer the reader to ref. 20 Perhaps the most substantial advancement of AgileFD for the phase mapping problem is the efficient modeling of Peak Shifting, which we enable by applying a log-transformation to the XRD patterns. Each XRD pattern can be represented as the scattering intensity (I) as a function of q, the magnitude of the X-ray scattering vector.…”

“…In ref. 20 we derive AgileFD's custom update rules for both H and W, which are derived from a loss function based on the generalized Kullback−Leibler divergence, an advancement that is critical for the phase mapping problem and is generally applicable for other source separation problems. With these lightweight update rules, this incorporation of Peak Shifting is vastly more efficient than the previously proposed time warping techniques.…”
