Deep Learning Techniques for Time Series Forecasting

Primary supervisor

Christoph Bergmeir

In modern "Big Data" environments often big quantities of related time series are available such as sales time series across different stores and products, measurements from many similar machines e.g. wind farms server farms etc. Forecasting in this case with traditional univariate forecasting procedures leaves great untapped potential for producing more accurate forecasts. Consequently big tech companies such as Amazon, Microsoft, and Uber have started recently to untap the enormous potentials of such datasets using deep learning methods in very successful ways for forecasting on their vast datasets. In particular recurrent neural networks are promising and my research team has already developed various models in this space.


As this area is my main area of research, there are various research topics available, around probabilistic forecasting (researching new loss functions), feature selection/engineering, transfer learning, causal inference, concept drift and online/stream learning, ensembling, local interpretability, evaluation procedures, seasonal factor decomposition, and others. You would be part of a very active research group with several PhD students, external collaborators, and connections to industry. I have topics available that range from rather theoretic to direct applications on real-world data from industry partners.
