Papers with open-domain dialogue generation
Attribute Controlled Dialogue Prompting (2023.findings-acl)
Copied to clipboard
| Challenge: | Prompt-tuning is an increasingly popular parameter-efficient method for adapting large pretrained language models to downstream tasks. |
| Approach: | They propose an instance-specific prompt-tuning algorithm for dialog generation that generates prompts based on instance-level control code rather than the conversation history. |
| Outcome: | The proposed prompt-tuning module is a fraction of the size of the pretrained language model and saves memory and expensive storage space. |
Thinking Clearly, Talking Fast: Concept-Guided Non-Autoregressive Generation for Open-Domain Dialogue Systems (2021.emnlp-main)
Copied to clipboard
| Challenge: | Existing models with seq2seq framework lack ability to effectively manage concept transitions . lack of concept management strategies might lead to incoherent dialogue due to loosely connected concepts . |
| Approach: | They propose a concept-guided non-autoregressive model for open-domain dialogue generation that learns to identify multiple associated concepts from a conceptual graph and a customized Insertion Transformer to perform concept-directed generation to complete a response. |
| Outcome: | The proposed model outperforms state-of-the-art models in automatic and human evaluations with substantially faster inference speed. |
Linguistically-Informed Specificity and Semantic Plausibility for Dialogue Generation (N19-1)
Copied to clipboard
| Challenge: | Past work has focused on word frequency-based approaches to improving specificity, such as penalizing responses with only common words. |
| Approach: | They propose to rerank a sequence-to-sequence model to improve the informativeness, reasonableness, and grammatically of responses by using externally-trained classifiers targeting each of these factors. |
| Outcome: | The proposed model improves the informativeness, reasonableness, and grammatically of responses. |
Are Training Samples Correlated? Learning to Generate Dialogue Responses with Multiple References (P19-1)
Copied to clipboard
| Challenge: | Existing approaches to open-domain dialogue generation ignore the nature of 1-to-1 mapping that there may exist multiple valid responses corresponding to the same query. |
| Approach: | They propose to model open-domain dialogue generation using 1-to-1 mapping . they first extract common features of different responses and then combine them with distinctive features to generate multiple diverse and appropriate responses. |
| Outcome: | The proposed model outperforms existing models on automatic and human evaluations. |
Diversifying Dialogue Generation with Non-Conversational Text (2020.acl-main)
Copied to clipboard
| Challenge: | Neural network-based sequence-to-sequence models suffer from low diversity in open-domain dialogue generation. |
| Approach: | They propose a way to diversify dialogue generation by leveraging non-conversational text . they collect large-scale corpus from forum comments, idioms and book snippets . |
| Outcome: | The proposed model produces significantly more diverse responses without sacrificing relevance with context. |
