| Challenge: | Existing work assumes the Gaussian priors of the latent variable, which are incapable of representing complex latent variables effectively. |
| Approach: | They propose to use the Dirichlet distribution with flexible structures to characterize latent variables in place of the Gaussian priors. |
| Outcome: | The proposed model outperforms existing models on the dialogue generation task. |

Copied to clipboard
| Challenge: | Experimental results show that our model can achieve a significant improvement in terms of metric-based evaluation and human evaluation compared with the state-of-the-art exposure bias approaches. |
| Approach: | They propose a novel adaptive switching mechanism which automatically transits between ground-truth learning and generated learning regarding the word-level matching score. |
| Outcome: | The proposed model improves on Chinese and English reddit datasets compared with state-of-the-art models on the word-level matching score. |
A Simple and Efficient Multi-Task Learning Approach for Conditioned Dialogue Generation (2021.naacl-main)
Copied to clipboard
| Challenge: | Existing studies have focused on conditioned dialogue generation, but there is a scarcity of labeled responses. |
| Approach: | They propose a multi-task learning approach to leverage labeled dialogue and text data to generate conditioned dialogues. |
| Outcome: | The proposed approach outperforms the state-of-the-art models by leveraging the labeled texts and obtains larger improvement compared to the previous methods to leverage text data. |
Dynamic Stochastic Decoding Strategy for Open-Domain Dialogue Generation (2024.findings-acl)
Copied to clipboard
| Challenge: | Stochastic sampling strategies are not widely used in open-domain dialogue systems. |
| Approach: | They propose a dynamic decoding strategy which can adjust the decoding space w.r.t. different contexts. |
| Outcome: | The proposed decoding strategy can improve the performance of pre-trained models when coupled with four well-used stochastic decoding algorithms. |
