Before revision:  Our state machine can model 96 \% of the human agent turns. Our training strategy improves by 9\% over a baseline that uses the same amount of hand-labeled data , showing the benefit of synthesizing data using the state machine .
After revision:  Our state machine can model 96 \% of the training data used in MultiWOZ 2.1. The MultiWOZ 2.4 dataset will be released upon publication .
