Data Mining and Statistical Analysis

Irina Roslyakova

The group works on the development of data mining strategies and their application to analysis and interpretation of materials data. Due to the high complexity and heterogeneity of materials data, we focus mainly on three key goals:

  • the establishment of a well-organized data infrastructure for storage of experimental data and simulation results,
  • the development of robust physics-based models of materials properties,
  • the application of data mining tools to identify statistically sound correlations between materials chemistry, microstructure and mechanical data.

Moreover, a combination of this modelling technique and the application of statistical design of experiments allow to reduce the number of experimental trials required for the development of new materials and processes.
