Machine learning with polynomials

Project description

# Effective Quadratures

Effective Quadratures is an open-source library for uncertainty quantification, machine learning, optimisation, numerical integration and dimension reduction – all using orthogonal polynomials. It is particularly useful for models / problems where output quantities of interest are smooth and continuous; to this extent it has found widespread applications in computational engineering models (finite elements, computational fluid dynamics, etc). It is built on the latest research within these areas and has both deterministic and randomized algorithms. Effective Quadratures is actively being developed by researchers at the [University of Cambridge](, [Imperial College London](, [Stanford University](, [The University of Utah](, [The Alan Turing Institute]( and the [University of Cagliari]( Effective Quadratures is a NumFOCUS affiliated project.

Key words associated with this code: polynomial surrogates, polynomial chaos, polynomial variable projection, Gaussian quadrature, Clenshaw Curtis, polynomial least squares, compressed sensing, gradient-enhanced surrogates, supervised learning.
