Zusammenfassung
This paper describes the use of Multi-Task Neural Networks (NNs) for system dialogue act selection. These models leverage the rep-resentations learned by the Natural Language Understanding (NLU) unit to enable robust initialization/bootstrapping of dialogue poli-cies from medium sized initial data sets. We evaluate the models on two goal-oriented di- alogue corpora in the travel booking domain. Results show the proposed models improve over models trained without knowledge of NLU tasks.
