Pneg: Prompt-based Negative Response Generation for Dialogue Response Selection Task (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods for synthesizing adversarial negative responses are limited by their scalability and cost. |
| Approach: | They propose a method for generating adversarial negative responses using a large-scale language model. |
| Outcome: | The proposed method outperforms other methods on dialogue selection tasks. |
Constructing Multi-Modal Dialogue Dataset by Replacing Text with Semantically Relevant Images (2021.acl-short)
Copied to clipboard
| Challenge: | Existing training methods for multi-modal dialogue systems rely on image captioning or visual question answering datasets that are irrelevant to the dialogue context. |
| Approach: | They propose to create a 45k multi-modal dialogue dataset with minimal human intervention . they use text dialogue datasets, image-mixed dialogues and contextual-similarity filtering . |
| Outcome: | The proposed dataset can be used as training data for multi-modal dialogue systems . human evaluations show that the model can be effectively used . |
