WASP offers 17 Postdoc positions

WASP announces call for postdoc positions in expedition projects
within AI, autonomous systems and software.

The expedition concept is modelled on NSF’s Expeditions in Computing and can be described as high gain/high risk targeted expeditions with a specific challenging goal rather than long term thematic frameworks. An expedition consists of two PIs and two to four PostDocs during two years. Applicants will be part of teams across departments or universities, with the aim to address compelling research topics that promise disruptive innovations in AI, autonomous systems and software for several years to come.

The expedition project positions that are offered in this call are listed below. Please follow the link to the coordinating university to read more and to apply.
Note the different last days for application.

 

Projects


ICARUS—Intelligent Cell-free Access for wiReless Ubiquitous Services

In this project, we will lay the practical foundation for operating autonomous “cell-free” wireless networks. Instead of breaking down the network operation into independent cells, all the access points in a cell-free network serve all users. The price to pay is a more challenging network operation. In this project, we will consider deep learning as a tool to overcome these challenges. We will apply existing methods and also develop new algorithms for the training problem with the aim to efficiently and reliably train deeper neural networks.

For this project four PostDoc positions are offered, two at Linköping University and two at Lund University. The contact persons are Emil Björnson, Division of Communication Systems, Department of Electrical Engineering, Linköping University,  emil.bjornson@liu.se, Announcement link to be provided, and Pontus Giselsson, Department of Automatic Control, Lund University, pontus.giselsson@control.lth.sePosition announcement (deadline January 2, 2019).

 

High-Confidence Formal Verification of Real Cyber-Physical Systems: from Models to Machine Code

In this project, we will lay the foundation for a completely new way of developing dependable cyber-physical systems. Today, low-level verified compilation exists (e.g., CompCert for C) and high-level models of systems are either tested using simulation (e.g., simulation of Modelica models), or small real-time models are analyzed in isolation (e.g., in tools like UPPAAL). However, there is a semantic gap between the verified models and the actual implementation of the final system. Models are tested or sometimes verified, but the implementation is independent, giving little confidence between the model and the actual implementation. The industry often resort back to traditional testing methodologies, without proofs of correctness, believing that formal proof guarantees are impossible in practice. Our expedition goal of this project is to show that what seems hardly possible in theory, is actually possible and feasible in practice.
This project brings formal verification-style guarantees to the developers of realistic CPSs. That is, the expected contributions are both theoretical (formal proofs in Coq and HOL4), as well as practical (a working tools that can synthesize time-accurate executable code from high-level models). Our long-term expedition vision is that this work changes the fundamental way safety critical cyber-physical systems are developed. Mathematically speaking, our vision is as follows: if a formal property is true for a model, then it also holds for the system. Such implication has only been assumed to be true in theory. This project will prove that it is true in practice.”

For this project three PostDoc positions are offered, two at KTH and one at Chalmers. Contact persons are David Broman, KTH, dbro@kth.se and Magnus Myreen, Chalmers, myreen@chalmers.se . Announcement links to be provided.

 

CorSA: Correct-by-design and Socially Acceptable Autonomy

As autonomous systems move from constrained environments into the social world in the form of self-driving vehicles and service robots, their interaction with and around people becomes inevitable. As a consequence, not only guarantees on their safety and performance are crucial, but social acceptability also becomes a key requirement. This project proposes to move from conventional correct-by-design control with simple, static human models towards the synthesis of correct-by-design and socially acceptable controllers that consider complex human models based on empirical data.

Our research objectives are:

(1) development of data-driven models of human behavior that enable the autonomous system to better respond in real-world situations and contribute to the social acceptability of the system; and (2) design of formal methods-based human-in-the-loop assumption-guarantee decision making and control synthesis algorithms, where the measure of social acceptability comes as an optimization criterion.

For this project two PostDoc positions are offered at KTH. The contact persons are Iolanda Leite, KTH, iolanda@kth.se  Position announcement, and Jana Tumova, KTH, tumova@kth.se  Position announcement (deadline for both positions January 15, 2019)

 

DEBLOAT: Code debloating from source code to large-scale deployment

The DEBLOAT WASP expedition focuses on the design of algorithms and the development of tools that remove unused code from the source code of the application down to the low-level systems libraries. This Expedition is motivated by the growing bloat in software applications : they integrate massive quantities of code that is never used in production but considerably reduces the speed of  software wastes resources, and increases risks of failure, and vulnerabilities.

For this project two PostDoc positions are offered, one at KTH and one at Umeå University. The contact persons are Benoit Baudry, Department of Software and Computer Systems, KTH, baudry@kth.sePosition announcement  (deadline January 15, 2019), and Erik Elmroth, Department of Computing Science, Umeå University, elmroth@cs.umu.se , Position announcement (deadline January 31, 2019)

 

Realtime Individualization of Brain Computer Interfaces

Controlling the physical world with our mind only, opens up for a vast number of exciting opportunities. Over the recent years, brain computer interfaces (BCIs) have improved steadily, both from advances in algorithms and in hardware. BCIs based on high time resolution electroencephalography (EEG) have a great potential in a wide area of applications. The overarching idea is to apply a tight feedback loop around the complete individualized BCI learning process. By connecting all stages of the learning process, including feature extraction from the input brain data to the classification of neural patterns, the aim is to drastically decrease the problem with long learning times and improve accuracy and reliability. Utilizing and extending a number of state-of-the-art techniques, such as optimal time-frequency representations, Riemann geometry based learning, dual control theory and cognitive modeling combined with edge based cloud computing the intention is to provide an efficient platform for next-generation BCIs, demonstrable within the time span of the project as a consumer-friendly EEG BCI.

Statistical signal processing subject description:

Massive, Secure, and Low-Latency Connectivity for IoT Applications

This expedition project aims at designing secure, privacy-preserving, and low-latency wireless connectivity solutions for cloud computing. We will target a multi-client scenario where a large number of sporadically active, resource-limited devices communicate to a powerful but untrusted cloud server. The goal is to establish a foundation for security and privacy in resource- and delay-constrained, multi-client and possibly multi-server cloud-assisted computing. We will characterize from a fundamental perspective how latency and energy efficiency scale as a function of the number of devices connected to the cloud server, as well as how these two quantities depend on the level of security and privacy provided by the communication and cloud-computing protocol.

The analysis will rely on tools from nonasymptotic information theory, statistics, signal processing, cryptography, and differential privacy.

For this project two PostDoc positions are offered, both at Chalmers. The contact persons are Giuseppe Durisi, durisi@chalmers.se, Department of Electrical Engineering, Position announcement (deadline December 20) and Katerina Mitrokotsa aikmitr@chalmers.se, Department of Computer Science and Engineering, Position announcement (deadline January 5).

 

Autonomous Optimization

The research in this project will focus on development of autonomous optimization, i.e. how to use tools from machine learning to automatically design and tune optimization algorithms. In particular, we plan to investigate how  to learn new efficient distributed optimization methods suitable for decision-making in autonomous systems and AI/ML.  The main research challenges of the project are in the intersection between optimization, control and machine learning. This is a collaborative project between the Optimization Group headed by Professor Anders Hansson within the Division of Automatic Control at the Department of Electrical Engineering  at Linköping University and the Department of Automatic Control headed by Professor Bo Wahlberg at KTH Royal Institute of Technology, Stockholm, Sweden.
