Full Description
In recent years, considerable progress has been made in research on artificial intelligence, particularly in the sub-area of machine learning (ML) where information is extracted from huge data sets. In practice, however, the existing data is often dirty, erroneous, not available in sufficient quantity, or does not meet the requirements for a direct application of ML methods. Against this background, data augmentation (DA) methods can be used to improve the data quality with the aim of enabling an initial application of ML methods or improving the results of existing ML models. Today, there is a wide range of different DA methods, which makes it oftentimes difficult to select an appropriate DA method for a particular application. Further, it remains unclear what the potential benefits and possible obstacles are to using DA for ML methods in practice. In this regard, this dissertation aims to contribute to a better understanding of DA and to demonstrate, by means of a multiple-case study, how DA can improve the performance and applicability of ML methods in the context of supply chain management.
