Description

Back to top

Algebraic statistics is a branch of mathematical statistics that focuses on the use of algebraic, geometric and combinatorial methods in statistics. The workshop will focus on three themes: (1) modeling environmental and ecological systems so that we can better understand the effects of climate change on these systems (2) reimaging urban development and economic systems to address persistent inequity in daily living activities and (3) providing theoretical underpinnings for statistical learning techniques to understand the implications of widespread use and for easy adaptation to novel applications.

These themes emerged in the Fall 2023 long program “Algebraic Statistics and our Changing World” hosted at IMSI. As the next chapter in the interdisciplinary field of algebraic statistics, this workshop is an exciting opportunity to expand on these themes. All participants interested in algebraic statistics are welcome.

Funding

Priority funding consideration will be given to those to register by May 20, 2025. Funding is limited.
