| Challenge: | Knowledge-dependent tasks typically use two sources of knowledge: parametric, learned at training time, and contextual, given as a passage at inference time. |
| Approach: | They propose a method to mitigate over-reliance on parametric knowledge, which minimizes hallucination, and improves out-of-distribution generalization by 4% - 7%. |
| Outcome: | The proposed method minimizes hallucination and improves generalization to evolving information by 4% - 7%. |
