A Survey of Active Learning for Text Classification using Deep Neural Networks

no code implementations17 Aug 2020 Christopher Schröder, Andreas Niekler

We review AL for text classification using deep neural networks (DNNs) and elaborate on two main causes which used to hinder the adoption: (a) the inability of NNs to provide reliable uncertainty estimates, on which the most commonly used query strategies rely, and (b) the challenge of training DNNs on small data.
