This is the best performing LAVA_kl model from the
LAVA paper which can be used as a word-level policy module in ConvLab3 pipeline.
Refer to
ConvLab-3 for model description and usage.
The model was trained on MultiWOZ 2.0 data using the
LAVA codebase. The model started with VAE pre-training and fine-tuning with informative prior KL loss, followed by corpus-based RL with REINFORCE.
