[CASPI] Causal-aware Safe Policy Improvement for Task-oriented Dialogue

no code implementations ACL 2022 Govardana Sachithanandam Ramachandran, Kazuma Hashimoto, Caiming Xiong

Further more we demonstrate sample efficiency, where our method trained only on 20% of the data, are comparable to current state of the art method trained on 100% data on two out of there evaluation metrics.

Causal-aware Safe Policy Improvement for Task-oriented dialogue

1 code implementation10 Mar 2021 Govardana Sachithanandam Ramachandran, Kazuma Hashimoto, Caiming Xiong

This method gives guarantees on dialogue policy's performance and also learns to shape rewards according to intentions behind human responses, rather than just mimicking demonstration data; this couple with batch-RL helps overall with sample efficiency of the framework.
