CEDAR Team

The CEDAR (ComplEx Data Analysis Research) Team works at the interface of harmonic analysis and machine learning. We develop tools that uncover complex, multiscale patterns in high dimensional data by considering the underlying data geometries, invariants, hierarchies and statistics. Our focus is on rigorous mathematical theory coupled with state of the art numerical results in application specific domains. Research areas include:

  • Wavelet theory and deep learning (scattering transforms)
  • Machine learning and many body problems in quantum chemistry and materials science
  • Geometric data analysis and manifold learning
  • Smooth (Whitney) extensions and interpolations of data
  • High dimensional data analysis, including bio-medical data
