| Challenge: | Retrieval-Augmented Generation (RAG) frameworks struggle with identifying whether retrieved documents meaningfully contribute to answer generation. |
| Approach: | They propose a document-related metric to quantify the contribution of retrieved documents to correct answer generation. |
| Outcome: | The proposed framework outperforms existing approaches on both single and multiple retrieval paradigms. |
Discretized Integrated Gradients for Explaining Language Models (2021.emnlp-main)
Copied to clipboard
| Challenge: | Integrated Gradients (IG) is widely adopted due to its desirable explanation axioms and the ease of gradient computation. |
| Approach: | They propose an attribution-based explanation algorithm that uses averaging the model's output gradient interpolated along a straight-line path in the input data space. |
| Outcome: | The proposed method is compared with IG on multiple sentiment classification datasets. |
