We invite submissions to the Learning Theory Workshop, to be held in Copenhagen on 26–27 June 2026, following the Learning Theory Summer School. 

The workshop aims to bring together researchers working on the theoretical foundations of machine learning, fostering discussion across a broad range of topics at the interface of learning theory, optimization, and modern ML applications. The workshop is preceded by the Learning Theory Summer School (June 22 - 25, 2026), which provides a great opportunity to learn about recent advancements at the core of modern machine learning practices. If you plan to attend the workshop then you also might be interested in attending the summer school, details of which can be found here: https://ltsscopenhagen.github.io 

The following (and related) paper categories are welcome:

• Generalization theory
• Optimization methods for machine learning
• Online and reinforcement learning
• Statistical and computational aspects of learning
• Privacy, unlearning, and fairness in machine learning
• Robustness and adversarial settings
• Foundations of deep learning

Submission Guidelines

Submit an abstract of at most 3000 characters for your contribution and optionally a link to a published version or a preprint. Submissions may present new results, work in progress, or recently published work. The workshop is intended to encourage interaction and exchange of ideas across different areas of learning theory and related fields. The workshop will have no proceedings.

The workshop invites two modes of presentation:

• Short talk (tentatively 15 - 20 minutes) and optional poster
• Poster only

Deadline for submission: May 10, 2026

Notification of acceptance: May 15, 2026

Registration deadline: May 24, 2026

Note: If your abstract gets accepted, one of the co-authors must present the contribution in person and register for the workshop (https://ltsscopenhagen.github.io/registration/). Please, respect the registration deadline of May 24, 2026.

We look forward to your contributions!
