Improving Personalized Explanation Generation through Visualization (2022.acl-long)
Copied to clipboard
| Challenge: | Existing explainable recommendation models generate repetitive sentences for different items or empty sentences with insufficient details. |
| Approach: | They propose a visual-enhanced approach to generate rating scores and text explanations using visualization generation and text–image matching discrimination. |
| Outcome: | The proposed approach improves both the text quality and the diversity and explainability of the generated explanations. |
VIP5: Towards Multimodal Foundation Models for Recommendation (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Recent advances in foundation models have impeded the ability for these fields to benefit from each other’s advancements. |
| Approach: | They propose to use a multimodal foundation model to unify various modalities and recommendation tasks under the P5 recommendation paradigm to implement personalized prompts. |
| Outcome: | The proposed model will unify visual, textual, and personalization modalities under the P5 recommendation paradigm and will improve recommendation performance and efficiency. |
