The research group in distributed system is internationally well-known and comprising more than 20 people of 10 different nationalities, and is currently recruiting up to 15 more researchers. The group’s research focuses on the (semi-)autonomous management of resources and applications to support the future digitized society. Target infrastructures range from single large-scale cloud datacenters to mobile edge clouds and includes individual servers, clusters, or disaggregated systems, such as rack-scale systems. The research spans from basic to applied research, and even innovation via spin-off companies. Collaborations are performed with industries like Google, IBM, Intel, Red Hat, and Ericsson, as well as universities and institutes such as Princeton University, University of Massachusetts Amherst, Carnegie Mellon University, Princeton University, Lawrence Berkeley Lab, Nanyang Technical University in Singapore, Uppsala University, Lund University, Universidad Complutense de Madrid, Leeds University, Barcelona Supercomputer Center, TU Vienna, TU Delft, and many more. See www.cloudresearch.org for a presentation of the group as well as an overview of ongoing research projects and publication lists.

Project description and working tasks

The rapid increase of autonomous systems, connected devices, and distributed applications pose challenges in dealing with petabytes of data in diverse resource-constrained environments. Federated machine learning (FML) is collaborative learning to handle these problems without sharing data with centralized servers. However, several emerging threats target FML training, learning, and inference to fail or mislead models at early learning rounds. Attackers aim to break trustworthiness under different threat models such as insiders-outsiders attacks, semi-honest or fully malicious participants, and attacks in training, learning, or inference phases. As a result, the learning models fail to provide acceptable performance. Therefore, this project aims to develop and implement trustworthy federated learning algorithms for scarce and diverse non-iid (independent identically distributed) data under non-standard and adversarial settings, which are ideally suited for constraint environments and edge computing infrastructures. These goals can be achieved by inducing unique features in federated learning algorithms such as decentralized training, optimal device selection, secure learning and inference, fault-tolerance against failures and attacks, as well as resilient, fair and robust models. The ambition is to validate them in classical non-standard settings and apply them to solutions for constraint environments (i.e., Industrial Internet of Things (IIoT), healthcare systems) and edge infrastructures. Potentially, teaching up to a maximum of 20% can be included in the work tasks.

Wallenberg AI, Autonomous Systems and Software Program (WASP) is Sweden’s largest individual research program ever, a major national initiative for strategically motivated basic research, education and faculty recruitment. The program addresses research on artificial intelligence and autonomous systems acting in collaboration with humans, adapting to their environment through sensors, information and knowledge, and forming intelligent systems-of-systems. The vision of WASP is excellent research and competence in artificial intelligence, autonomous systems and software for the benefit of Swedish industry. Read more: https://wasp-sweden.org/

Qualifications

To be appointed under the postdoctoral agreement, the postdoctoral fellow is required to have completed a doctoral degree or a foreign degree deemed equivalent to a doctoral degree. This qualification requirements must be fulfilled no later than at the time of the appointment decision.

To be appointed under the postdoctoral agreement, priority should be given to candidates who completed their doctoral degree, according to what is stipulated in the paragraph above, no later than three years prior. If there are special reasons, candidates who completed their doctoral degree prior to that may also be eligible. Special reasons include absence due to illness, parental leave, appointments of trust in trade union organisations, military service, or similar circumstances, as well as clinical practice or other forms of appointment/assignment relevant to the subject area. Postdoctoral fellows who are to teach or supervise must have taken relevant courses in teaching and learning in higher education.

Ideal candidates are research-driven, organized, and would like to work on challenging problems and innovative solutions. We are open to candidates with strengths in federated machine learning under multi-constraints settings and relevant to the research environment. Knowledge and experience in federated learning algorithms, distributed algorithms, learning with data scarcity, data-centric optimization, resilient or fault-tolerant learning, trustworthy learning, mathematical statistics, anomaly detection, cloud-native systems, serverless systems, etc. is desirable.
