“None of the Above”: Measure Uncertainty in Dialog Response Retrieval (2020.acl-main)
Copied to clipboard
| Challenge: | End-to-end (E2E) dialog retrieval models jointly encode a dialog and a candidate response, assuming the ground truth is always present in the candidate set. |
| Approach: | They propose to capture the original retrieval model's confidence concerning the best prediction using trivial additional computation. |
| Outcome: | The proposed model can capture the model's confidence concerning the best prediction using trivial additional computation. |
Interactive Evaluation of Dialog Track at DSTC9 (2022.lrec-1)
Copied to clipboard
| Challenge: | Currently, dialog research is focused on static data, which neglects multiple important properties of dialog, such as consistency, topic depth, adaptation, error recovery and user-centric development. |
| Approach: | They propose to use static dialogs to build strong response generation models and extend them to back-and-forth interactions with real users. |
| Outcome: | The proposed model trains a larger evolved Transformer model on social media data and attains strong performance in interactive settings. |

| Challenge: | a novel task of predicting adverbial presupposition triggers is useful for natural language generation . a focus is on a new attention mechanism for predicting presuposition trigger . |
| Approach: | They propose a new attention mechanism for predicting adverbial presupposition triggers . they propose to augment a baseline neural network without additional trainable parameters . |
| Outcome: | The proposed model outperforms baseline models in predicting adverbial presupposition triggers. |
