Description du poste

According to the principles governing data protection regulations, personal data can be used for training machine learning models as soon as this finality is compatible with the purposes for which data has been collected. However, recent research has shown that that the training data, a subset of it, or information about who was in the training set, can in certain cases be reconstructed from models leading to data breaches [1,2].

Anonymization with differential privacy offers provable guarantees against re-identification and membership inference attacks. During the internship the student will investigate how to maintain data utility and to preserve privacy when training deep learning models. Building on previous results [3], new experiments to find how to reduce privacy budget consumption during training will be designed. These will employ transfer learning, for instance as done in [4], but with the fundamental difference that we will deliver anonymized data as output, not models.

In the above-described context, the specific goals of the internship are as follows:
• Experiment with GANs/VAEs using differential privacy for multiple datasets see https://github.com/SAP-samples/security-research-differentially-private-generative-models
• Design an architecture to optimize differential privacy budget consumption using transfer learning for generative model training
• Experiment with different transfer learning techniques to train generative models with differential privacy

Technologies/techniques involved are: Python, Tensorflow, SKLearn and Machine Learning in general

We expect that 70% of time will be dedicated to research activities, and 30% to development

Profil recherché

• University Level: Last year of MSc or less if the student has a good profile
• Good knowledge of the Python programming language
• Good knowledge of versioning control systems like GIT or SVN
