Abstract
Deep learning continues to receive increasing attention from researchers and has been successfully applied to many domains. This paper further extends the work from Zabihi Naeini and Prindle (2018) by adopting and examining two classes of Machine Learning techniques and their applications in geoscience with a pragmatic view. These are Transfer Learning and Automated Machine Learning or Auto-ML (Feurer and Klein, 2015). Although machine learning (ML) is known to be most efficient and accurate when trained on a large volume of data, there are cases in practice where ML methods are also implemented with limited available data. In such cases ML algorithms are less efficient in generalising to new data and it is where Transfer Learning can add value. This is shown in an automatic petrophysical interpretation task where Transfer Learning is compared with training from scratch given a new geological area of interest, i.e., a set of wells in a different area. We show the efficiency of Transfer Learning in obtaining a model that generalizes successfully for the new wells investigated.
