20–24 February 2023

The High-Dimensional Approximation (HDA) Workshop is a series of biennial international meetings covering current research on high-dimensional problems. This ninth workshop (HDA2023) will be held at ANU in Canberra.

HDA2023 will cover a range of topics central to modern high-dimensional approximation and their applications. Topics include, but are not limited to,

  • Nonlinear approximation
  • Numerical integration
  • Tensor decomposition
  • Sparsity-exploiting approximation
  • Sparse grid methods
  • Quasi-Monte Carlo methods
  • Polynomial chaos expansions
  • Discrepancy and dispersion theory
  • Dimensionality reduction
  • Uncertainty quantification
  • Reduced modelling
  • Inverse problems

Participants are welcomed from all around the world. A key feature of this workshop is that there are no parallel sessions and generally all talks are of equal length. Participants are welcome to present work in progress, and time will be set aside for informal discussions. The number of talks will be limited. It is not essential that everyone gives a talk. Collaborators are encouraged to coordinate and elect a representative to present joint work.

About Canberra

Canberra is located in the Australian Capital Territory, on the ancient lands of the Ngunnawal people, who have lived here for over 20,000 years. Canberra’s name is thought to mean ‘meeting place’, derived from the Aboriginal word Kamberra. European settlers arrived in the 1830s, and the area won selection by ballot for the federal capital in 1908. Since then the ‘Bush Capital’ has grown to become the proud home of the Australian story, with a growing population of around 390,000.

Canberra hosts a wide range of tourist attractions, including various national museums, galleries and Parliament House, as well as beautiful parks and walking trails. Several attractions are within walking distance of the ANU campus, including the National Museum of Australia and the Australian National Botanic Gardens. Canberra is also a fantastic base from which to explore the many treasures of the surrounding region, including historic townships, beautiful coastlines and the famous Snowy Mountains. Learn more about what to do and see during your stay in Canberra.


International visitors to Australia require a visa or an electronic travel authority (ETA) prior to arrival. It is your responsibility to ensure documentation is correct and complete before you commence your journey. Visit the Australian Immigration and Citizenship website for information about visas and ETAs.


There are many ways to get around Canberra. Below is some useful information about Bus & Taxi transport around the ANU, the Airport and surrounding areas.


If you are catching a taxi or Uber to the ANU Mathematical Sciences Institute, ask to be taken to Building #145, Science Road, ANU. We are located close to the Ian Ross Building and the ANU gym. A Taxi from the airport will usually cost around $40 and will take roughly 15 minutes. Pricing and time may vary depending on traffic.

Phone Canberra Elite Taxis on 13 22 27 to book a taxi.


Canberra buses are a cheap and easy way of getting around town once you're here. View bus services and fares information on the Transport Canberra website.

To travel just use your MyWay card or pay a cash fare to the driver when boarding. A single adult trip when paying cash will cost $4.80 with cheaper fares for students and children. Significant savings can be made when travelling with MyWay. View MyWay and Fares information.
