- W4287253168 abstract "In many cases of machine learning, research suggests that the development of training data might have a higher relevance than the choice and modelling of classifiers themselves. Thus, data augmentation methods have been developed to improve classifiers by artificially created training data. In NLP, there is the challenge of establishing universal rules for text transformations which provide new linguistic patterns. In this paper, we present and evaluate a text generation method suitable to increase the performance of classifiers for long and short texts. We achieved promising improvements when evaluating short as well as long text tasks with the enhancement by our text generation method. In a simulated low data regime additive accuracy gains of up to 15.53% are achieved. As the current track of these constructed regimes is not universally applicable, we also show major improvements in several real world low data tasks (up to +4.84 F1 score). Since we are evaluating the method from many perspectives, we also observe situations where the method might not be suitable. We discuss implications and patterns for the successful application of our approach on different types of datasets." @default.
