Hybrid modelling

The dynamics of ecosystems and earth systems are often difficult to model and predict, and even today many machine learning approaches fail to encode temporal dependencies that typically characterize dynamic natural systems. However, deep learning approaches in the time domain (e.g. recurrent neural networks) are conceptually capable of solving such problems. However, such models are difficult or impossible to interpret physically, which limits the scientific knowledge gained from them.

The combination of machine learning and physically-based modeling, hybrid modeling , is intended to research and further develop possible ways of gaining scientific knowledge about the observed phenomena despite the black box character of the models used and thus the potential of temporal deep learning approaches for to be able to use the modeling of ecosystem processes.
