Copied to clipboard
| Challenge: | Large Language Models (LLMs) are gaining a foothold in Recommender Systems (RS) but there is growing concern that LLMs perpetuate stereotypes and may result in unfair recommendations. |
| Approach: | They propose a counterfactually-fair-prompt method for LLM-based recommendation that is based on unbiased foundation mOdels. |
| Outcome: | The proposed method achieves better recommendation performance with a high level of fairness on two real-world datasets. |

| 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. |
