Master thesis: Decentralized deep learning and continual learning

Introduction The study of deep learning on decentralized data has been of interest for a long time. Modern mobile devices are equipped with sensors that can collect a multitude of data streams related to people's everyday lives, providing a promising source of training data. With the global spread of smartphones and other mobile devices, an immense increase of data collected has highlighted the need for responsible mining. Such data requires special care not only due to increasing privacy concerns among users but also due to regulatory privacy laws.

Distributed data collection unlocks the potential of data that would otherwise be difficult or impossible to obtain. Existing solutions (e.g. federated learning) generally assume that the data is drawn from a stationary underlying distribution, and that the data of the past is similar to the data of the future. However, in practice, different clients often have different types of biases and their data may not always be independently and identically distributed (iid). This results in differing client data distributions (the non-iid data paradigm), which hinders efficient training of deep learning models.

An underexplored research problem is continual learning in decentralized settings, where the goal is to study deep learning on non-stationary distributions. It is still unclear how to mitigate catastrophic forgetting and learn useful representations as distributions shift in a decentralized setting.

Thesis Description In this master thesis, you will work on decentralized learning and continual learning, investigating methods to learn useful deep learning representation when data distributions shift in time and space. You will work in close collaboration with our deep learning research group in Gothenburg. The work requires skilled students within machine learning and statistical inference. You will be expected to do a literature study in order to get familiar with what the research field looks like today, and then start with simpler models and eventually extend or develop upon more advanced solutions. This will be a research oriented master thesis.
