Call for papers

We invite researchers to submit work in any of the following areas:

  • Uncertainty in deep learning,
  • probabilistic deep models (such as extensions and application of Bayesian neural networks),
  • deep probabilistic models (such as hierarchical Bayesian models and their applications),
  • deep generative models (such as variational autoencoders),
  • practical approximate inference techniques in Bayesian deep learning,
  • connections between deep learning and Gaussian processes,
  • applications of Bayesian deep learning,
  • or any of the topics below.

A submission should take the form of an extended abstract (3 pages long) in PDF format using the NeurIPS 2019 style. Author names do not need to be anonymized, and conflicts of interest in assessing submitted contributions will be based on this (reviewers will not be involved in the assessment of a submission by authors within the same institution). References may extend as far as needed beyond the 3 page upper limit. Submissions may extend beyond the 3 pages upper limit, but reviewers are not expected to read beyond the first 3 pages. If the research has previously appeared in a journal, workshop, or conference (including the NeurIPS 2019 conference), the workshop submission should extend that previous work. Dual submissions to ICLR 2019, AAAI 2019, and AISTATS 2019 are permitted.

Submissions will be accepted as contributed talks or poster presentations. Extended abstracts should be submitted by September 9, 2019 Deadline has been extended to Friday, September 13, 2019; submission page is here. Final versions will be posted on the workshop website (and are archival but do not constitute a proceedings). Notification of acceptance will be made before October 1, 2019.

Key Dates:

  • Extended abstract submission deadline: September 9, 2019 (23:59 AOE) Deadline has been extended to Friday, September 13, 2019 (23:59 AOE) (submission page is here)
  • Acceptance notification: before October 1, 2019
  • Camera ready submission: 30 October 2019
  • Workshop: Friday, December 13, 2019

Please make sure to apply to the lottery registration as the workshop is allocated a limited number of tickets. We will do our best to guarantee workshop registration for all accepted workshop submissions which did not receive a lottery registration.


While deep learning has been revolutionary for machine learning, most modern deep learning models cannot represent their uncertainty nor take advantage of the well studied tools of probability theory. This has started to change following recent developments of tools and techniques combining Bayesian approaches with deep learning. The intersection of the two fields has received great interest from the community over the past few years, with the introduction of new deep learning models that take advantage of Bayesian techniques, as well as Bayesian models that incorporate deep learning elements [1-11]. In fact, the use of Bayesian techniques in deep learning can be traced back to the 1990s’, in seminal works by Radford Neal [12], David MacKay [13], and Dayan et al. [14]. These gave us tools to reason about deep models’ confidence, and achieved state-of-the-art performance on many tasks. However earlier tools did not adapt when new needs arose (such as scalability to big data), and were consequently forgotten. Such ideas are now being revisited in light of new advances in the field, yielding many exciting new results.

Extending on last year’s workshop’s success, this workshop will again study the advantages and disadvantages of such ideas, and will be a platform to host the recent flourish of ideas using Bayesian approaches in deep learning and using deep learning tools in Bayesian modelling. The program includes a mix of invited talks, contributed talks, and contributed posters. It will be composed of five themes: deep generative models, variational inference using neural network recognition models, practical approximate inference techniques in Bayesian neural networks, applications of Bayesian neural networks, and information theory in deep learning. Future directions for the field will be debated in a panel discussion.
