Learning an Unreferenced Metric for Online Dialogue Evaluation (2020.acl-main)
Copied to clipboard
| Challenge: | Existing tools for dialogue evaluation do not generalize to unseen datasets and/or need a human-generated reference response during inference. |
| Approach: | They propose an unreferenced automated dialogue evaluation metric that uses large pre-trained language models to extract latent representations of utterances and leverages the temporal transitions that exist between them. |
| Outcome: | The proposed model achieves higher correlation with human annotations in an online setting, while not requiring true responses for comparison during inference. |
Seeded self-play for language learning (D19-64)

| Challenge: | Current methods for learning human language are too data inefficient to learn it in this way. |
| Approach: | They propose to train a meta-learning agent in simulation to interact with populations of pre-trained agents, each with their own distinct communication protocol. |
| Outcome: | The proposed algorithm minimizes the number of on-policy interactions while learning human language while minimizing the number on-political interactions. |
