Welcome
The High-Dimensional Approximation (HDA) Workshop is a series of biennial international meetings covering current research on high-dimensional problems.
HDA2025 will cover a range of topics central to modern high-dimensional approximation and their applications.
Methods include, but are not limited to,
- Deep neural networks
- Kernel approaches
- Quasi-Monte Carlo approaches
- Sparse grids
- Low rank tensor decompositions
- Dimensionality reduction
- Function approximation
- Approximation in Chemistry, Physics and other Sciences
- Numerical solution of partial differential equations
- Inverse problems
- Machine learning
- Numerical integration
- Reduced order modelling
- Uncertainty quantification

Transportation
- By plane to Flughafen Köln Bonn. Take Bus SB60 to Bonn Hauptbahnhof (runs about every 30 minutes, 35-minute ride).
- By plane to Flughafen Düsseldorf. Take the train from Flughafen Düsseldorf to Bonn Hauptbahnhof.
- By plane to Flughafen Frankfurt. Take the train from Flughafen Frankfurt to Bonn Hauptbahnhof. Either as a (highly recommended) scenic train ride along the river Rhein or with a somewhat faster connection over Siegburg/Bonn. The train ticket may be included in or booked with your long-distance airfare.
Financial Support
Financial support is given by the TRA Modelling (University of Bonn) and the Hausdorff Center for Mathematics (HCM) as part of the Excellence Strategy of the federal and state governments, as well as the CRC1639 NuMeriQS.
