MidFull TimeEN
We are searching for a PhD student or a Postdoctoral Researcher to research the way data can be augmented from existing data. Data augmentation is the process of artificially generating new data from existing data. The augmented data shares similar trades as ‘real data’, but is indeed not the data itself. Data augmentation is an area of interest when it comes to health data, as health data is often limited in volume, costly to collect, and augmentation can thereby be an area of interest to explore, for exploring the future of training machine learning models.
The position is funded through the LUMI AI Factory (EuroHPC) and focuses on scalable AI-for-science workflows using GPU-accelerated computing, and this particular position focuses on researching data augmentation of health data within the field of information systems.
The candidate will work at the intersection of information systems, machine learning, computer science, and digital health, in close collaboration with a faculty member from the Department of Computer Science, who shares this interest. We are looking for someone with the ambition to grow into a well-rounded information systems researcher, writing papers that will aim high, in collaboration with the supervisor and others. The candidate should ideally have a background and interest in information systems as a field of research, with skills and capabilities in machine learning, and an interest in making an impact on healthcare through data augmentation. The position will be either a PhD position or a Postdoctoral Researcher position, depending on the applications that come in for the position. If it is a PhD position, then it will be for three years. If it is a Postdoctoral Researcher position, then the funding will cover a two-year term.
Research focus
Health data is limited, and collecting it is costly and often invasive. Augmenting the existing data with synthetic data would be a novel approach to addressing the issue of limited data in order to increase the volume of training data, but that is, however, tricky due to ethical, legal, and computational concerns. This position will focus on the investigation of how data augmentation can be designed, evaluated, and applied to health data in order to improve data volume, availability, and ultimately performance of machine learning models.
Data augmentation to artificially increase the dataset by modifying copies of existing data or synthetically generating new copies by using the existing dataset can have its benefits. While training the machine learning model, it acts as regularization and reduces overfitting, and also could potentially allow data to be shared, but data augmentation can, however, also have immense ethical concerns linked to it. This research is focused on those aspects, and titrating approaches towards reaching realistic data while shedding light on the dark and bright aspects of data augmentation, while also developing an understanding of how health data can be augmented in a thoughtful manner.
The exact research direction will be co-designed based on the candidate’s interests and background in cohesion with the project goals.
