About the position

We have a vacancy for a PhD candidate in Privacy Preserved Machine Learning at The Department of Computer Science (IDI)

The Department of Computer Science (IDI) in Gjøvik invites applications for a PhD/Early Stage Researcher position in Computer Science. The position will be based at The Norwegian Colour and Visual Computing Laboratory.

The main task of the PhD student in the doctoral work will be twofold. First, to study and investigate the classical machine learning approaches and enable them with the privacy preserving ability. Secondly, to develop meaningful techniques that facilitate the privacy preserving mechanisms (for e.g., Homomorphic Encryption) for deep learning approaches for classification and prediction tasks using images. Depending on the skills of the candidate, different aspects may be emphasized, for instance by focusing on:

  • Privacy preserving for signal/image processing under classical machine learning
  • Privacy preserving for deep learning and transfer learning
  • Privacy preserving/enhancing techniques resilient against model inversion attacks
  • Differential privacy preserving for machine learning and deep learning

The position reports to Head of department

Place of work is Gjøvik.

Main duties and responsibilities

The candidate is expected to work towards combining knowledge from machine learning, signal/image processing and privacy preserving/enhancing approaches to define new methods for deriving privacy preserved machine learning, and to publish the results in scientific journals and conferences.

During the employment period, the candidate may spend a stipulated period for internship at the other reputed universities/groups working on similar domain.
