2026 Frontiers in Learning Under Data Heterogeneity

January 16-17, 2026

The University of Florida Department of Statistics’ Annual Winter Workshop will take place on January 16-17, 2026 (Friday-Saturday).

The workshop will be in-person in the Reitz Union Chamber.

A fundamental challenge in modern data science involves developing rigorous methods for statistical inference and machine learning when working with heterogeneous data. Real-world datasets frequently originate from diverse sources spanning multiple domains, institutions, and subpopulations, creating complex distributional shifts that violate traditional modeling assumptions. This workshop will unite researchers bridging theory and application to explore recent advances addressing such variability through principled approaches. Key topics encompass generalization under distribution shift, adaptation strategies for covariate and label shift, invariant representation learning, and robust aggregation frameworks in decentralized environments. The event will connect statisticians, machine learning researchers, AI scientists to identify emerging challenges and chart future research questions. All sessions will be conducted as plenary presentations.

Poster Presentations

The workshop will also include a poster session. Funding is expected to support a limited number of young researchers to attend the workshop and present their work at the poster session.

The organizing committee is soliciting applications from senior
graduate students (4th year or higher) and researchers who received
their Ph.D. in or after 2020.

Applications should include a curriculum vitae, a one-page abstract, and the names of two references, including a major professor who is supervising (or has supervised) the applicant’s research.

Applications should be uploaded to Google forms via this link:
