Review the basics of ODEs/PDEs, the Kaluza-Klein Theory, and the DSPA materials.

Outline: The SOCR Data Science Fundamentals project explores new theoretical representations and analytical strategies to understand large and complex data. It utilizes information measures, entropy, KL divergence, PDEs, and Dirac’s bra-ket operators. This fundamentals of data science research project employs time-complexity and inferential uncertainty for representation, modeling, analysis and interpretation of large, heterogeneous, multi-source, multi-scale, incomplete, incongruent, and longitudinal data.
