1. A computer-implemented dimensionality analysis method, the method comprising:
- defining a free-form grammar that describes an admissible relationship between quantities in a data set;
discovering symbolic expressions that intrinsically account for a dimensionality analysis based on the grammar;
conducting a search that determines which valid expressions in the data set satisfies the grammar and that determines a measure of a complexity of the expression; and
selecting the valid expressions that fits the dataset and minimizes the measure of the complexity of the expression.

Abstract
A dimensionality analysis method, system, and computer program product, include defining a grammar that describes an admissible relationship between quantities in a data set, discovering symbolic expressions that intrinsically account for a dimensionality analysis based on the grammar, conducting a search that determines which valid expression in the data set satisfy the grammar, and selecting the expression that fits the dataset and minimizes a measure of a complexity of the expression.
