International Workshop on Federated Learning: Recent Advances and New Challenges
in Conjunction with NeurIPS 2022 (FL-NeurIPS'22)


Submission Due: September 21, 2022 (23:59:59 PDT, UTC-7)
Notification Due: October 20, 2022
Workshop Date: Friday, December 2, 2022
Venue: New Orleans Convention Center, New Orleans, LA, USA

Call for Papers

Training machine learning models in a centralized fashion often faces significant challenges due to regulatory and privacy concerns in real-world use cases. These include distributed training data, computational resources to create and maintain a central data repository, and regulatory guidelines (GDPR, HIPAA) that restrict sharing sensitive data. Federated learning (FL) is a new paradigm in machine learning that can mitigate these challenges by training a global model using distributed data, without the need for data sharing. The extensive application of machine learning to analyze and draw insight from real-world, distributed, and sensitive data necessitates familiarization with and adoption of this relevant and timely topic among the scientific community.

Despite the advantages of FL, and its successful application in certain industry-based cases, this field is still in its infancy due to new challenges that are imposed by limited visibility of the training data, potential lack of trust among participants training a single model, potential privacy inferences, and in some cases, limited or unreliable connectivity.

The goal of this workshop is to bring together researchers and practitioners interested in FL. This day-long event will facilitate interaction among students, scholars, and industry professionals from around the world to understand the topic, identify technical challenges, and discuss potential solutions. This will lead to an overall advancement of FL and its impact in the community, while noting that FL has become an increasingly popular topic in the machine learning community in recent years.

Topics of interest include, but are not limited to, the following:
  • Adversarial attacks on FL
  • Applications of FL
  • Blockchain for FL
  • Beyond first-order methods in FL
  • Beyond local methods in FL
  • Communication compression in FL
  • Data heterogeneity in FL
  • Decentralized FL
  • Device heterogeneity in FL
  • Fairness in FL
  • Hardware for on-device FL
  • Variants of FL like split learning
  • Local methods in FL
  • Nonconvex FL
  • Operational challenges in FL
  • Optimization advances in FL
  • Partial participation in FL
  • Personalization in FL
  • Privacy concerns in FL
  • Privacy-preserving methods for FL
  • Resource-efficient FL
  • Systems and infrastructure for FL
  • Theoretical contributions to FL
  • Uncertainty in FL
  • Vertical FL

The workshop will have invited talks on a diverse set of topics related to FL. In addition, we plan to have an industrial panel and booth, where researchers from industry will talk about challenges and solutions from an industrial perspective.

Submission Instructions

Submissions should be no more than 6 pages long, excluding references, and follow NeurIPS'22 template. Submissions are double-blind (author identity shall not be revealed to the reviewers), so the submitted PDF file should not include any identifiable information of authors. An optional appendix of any length is allowed and should be put at the end of the paper (after references).

Submissions are collected on OpenReview at the following link: https://openreview.net/group?id=NeurIPS.cc/2022/Workshop/Federated_Learning.
Accepted papers and their review comments will be posted on OpenReview in public. Due to the short timeline, we will not have a rebuttal period, but the authors are encouraged to interact and discuss with reviewers on OpenReview after the acceptance notifications are sent out. Rejected papers and their reviews will remain private and not posted in public.

For questions, please contact: fl-neurips-2022@googlegroups.com


Proceedings and Dual Submission Policy

Our workshop does not have formal proceedings, i.e., it is non-archival. Accepted papers will be available in public on OpenReview together with the reviewers' comments. Revisions to accepted papers will be allowed until shortly before the workshop date.

We welcome submissions of unpublished papers, including those that are submitted to other venues if that other venue allows so. However, papers that have been accepted to an archival venue as of Sept. 21, 2022 should not be resubmitted to this workshop, because the goal of the workshop is to share recent results and discuss open problems. Specifically, papers that have been accepted to NeurIPS'22 main conference should not be resubmitted to this workshop.


Presentation Format

The workshop will primarily take place physically with in person attendance. For presenters who cannot attend in person, it is planned to be made possible to connect remotely over Zoom for the oral talks. However, the poster sessions will be in-person only. Depending on the situation, we may include a lightening talk session for accepted poster presentations where the presenters cannot attend physically, or organize a separate virtual session after the official workshop date. If a paper is accepted as an oral talk, the NeurIPS organizers require a pre-recording of the presentation by early November, which will be made available for virtual participants to view. All accepted papers will be posted on OpenReview and linked on our webpage.
