This workshop, sponsored by AIM and the NSF, will be devoted to singular learning theory, the application of algebraic geometry to problems in statistical model selection and machine learning. The intent of this workshop is to connect algebraic geometers and statisticians specializing in Bayesian model selection criteria in order to explore the relationship between analytical asymptotic approximations from algebraic geometry and other commonly used methods in statistics (including traditional asymptotic and Monte Carlo approaches) for developing new model selection criteria. The hope is to generate interest amongst both communities for collaborations that will spur new topics of research in both algebraic geometry and statistics.
Singular statistical learning is an approach for statistical learning and model selection that can be applied to singular parameter spaces, i.e. can be used for non-regular statistical models. The methodology uses the method of resolution of singularities to generalize the criteria for regular statistical models to non-regular models. Examples of non-regular statistical models that have been studied as part of singular learning theory include hidden Markov models, finite mixture models, and multi-layer neural network models. Although there exists a large body of recent published work in this area, it is has not yet been integrated or even well-cited by the larger statistical community.
The workshop has three primary goals:
The workshop will differ from typical conferences in some regards. Participants will be invited to suggest open problems and questions before the workshop begins, and these will be posted on the workshop website. These include specific problems on which there is hope of making some progress during the workshop, as well as more ambitious problems which may influence the future activity of the field. Lectures at the workshop will be focused on familiarizing the participants with the background material leading up to specific problems, and the schedule will include discussion and parallel working sessions.
The deadline to apply for support to participate in this workshop has passed.
