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:
- Mathematical foundations of deep learning
- Geometric and topological methods for high dimensional data analysis, including geometric deep learning
- Smooth extension and interpolation of data, with efficient algorithms (Whitney-type extensions)
- Multi-reference alignment inverse problems
- Machine learning and quantum many body physics
- Biological data analysis
- Stochastic processes
- Quantum computing and quantum information science
