After the introductory Chapters 1 and 2, we continue with the publication-based
chapters that form the core of the thesis, which are structured in two parts.
Part I consists of a single chapter, Chapter 3, which presents a benchmarking
study of PUQ methods applied on real-world text classification datasets with
1-D convolutional neural networks and pretrained transformers. It motivates
a novel PUQ method, Deep Ensemble with Concrete Dropout, combining the
benefits of both methods, and showing promise for improving reliability and
robustness in NLP at a lower computational cost. The chapter concludes with
a discussion of the results, including targeted ablation studies, and provides
recommendations for future research.
Part II consists of three chapters, Chapters 4 to 6, which all focus on the more
applied research questions of realistic and efficient DU.
