PhD Student Position in Machine Learning: Causality & Efficiency

Chalmers University of Technology

Sweden

October 2, 2022

Description

The data science and AI division at CSE is recruiting a PhD student in machine learning for a project on the efficient generalization using causality and auxiliary information.

Information about the project Machine learning is now an essential tool for scientists and engineers. It is used in diverse applications to predict outcomes from inputs by training models to minimize prediction error in training data. As widespread adoption reaches beyond research and the developers of such systems, the seams have started to show in this attractively simple idea. State-of-the-art models which achieve top accuracy on benchmark tasks fail to generalize to new examples and to highly related problem domains. In this project, we will study the combination of causal inference and learning using auxiliary information to improve the efficiency and domain robustness of learning algorithms.

Generalization in machine learning refers to a trained system performing well on previously unseen examples. These new examples are often assumed to follow the same distribution as training examples, which guarantees good generalization if the number of samples is large enough. In real-world applications, however, data often follows different patterns: 1) We often have access to different (auxiliary) information at training time than we do when the trained system is deployed, 2) The distribution of in-deployment samples often differs from those collected for training, 3) The number of samples is rarely as large as we would like it to be. In this project, we will develop sample-efficient learning algorithms which makes the best possible use of small numbers of training examples by exploiting auxiliary information and causal assumptions.

The position is placed in the research group led by Fredrik Johansson, currently comprised of 5 PhD students working on topics related to machine learning for improved decision making with applications in healthcare. The project is supported by the Wallenberg AI, Autonomous Systems and Software Program (WASP) funded by the Knut & Alice Wallenberg Foundation.

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/

The graduate school within WASP is dedicated to provide the skills needed to analyze, develop, and contribute to the interdisciplinary area of artificial intelligence, autonomous systems and software. Through an ambitious program with research visits, partner universities, and visiting lecturers, the graduate school actively supports forming a strong multi-disciplinary and international professional network between PhD-students, researchers and industry.

Major responsibilities Your major responsibilities as a PhD student is to pursue your own doctoral studies. You will be enrolled in a graduate program in the Department of Computer Science and Engineering. You are expected to develop your own ideas and communicate scientific results orally as well as in written form. In addition, the position will include 20% departmental work, mostly teaching duties in Chalmers' undergraduate and masters-level courses or performing other duties corresponding to 20% of working hours.

Qualifications To qualify as a PhD student, you must have a master's-level degree, or a four-year bachelor's degree, corresponding to at least 240 higher education credits in a relevant field. The position requires sound verbal and written communication skills in Swedish and English. If Swedish is not your native language, you should be able to teach in Swedish after two years. Chalmers offers Swedish courses.

Contract terms Full-time temporary employment. The position is limited to a maximum of five years.
