Special Issue Introduction
Materials design drives the innovation of materials science and engineering to meet the increasing demands for high performance, low cost, and environmentally benign materials. The challenges of materials design originate from the complex materials parameters including compositions, structures, and processing parameters as well as the multiple materials properties often behaving with contradictory trends. It is a long-term challenging problem to discover the complex and usually highly nonlinear relationships between the composition/structure/processing and property/performance (CSP-PP). Thanks to the recent surge of big-data and artificial intelligence (AI) techniques, the data-driven approach emerges as the fourth research paradigm in addition to the experiment, theory, and computation. The data-driven methods, e.g., machine learning (ML), provide a new powerful tool to overcome the difficulty of discovering CSP-PP relationships that often lacks of explicit analytical theory. The ML methods can be developed on the basis of the large data extracted from the existing materials databases, collected from the published literatures, or generated by experimental or computational methods. The efficient generation of a large amount of data requires to carry out computations and experiments systematically in high-throughput manners. The ML applications in materials science gave birth to the emerging field of materials informatics with the naturally close integration with materials database, high-throughput computation, and high-throughput experiment, forming the motivation of this special issue.
