SSS: Editing Factual Knowledge in Language Models towards Semantic Sparse Space (2024.findings-acl)
Copied to clipboard
| Challenge: | Existing methods to modify LMs suffer from sub-optimal locality, where irrelevant neighborhood examples can be adversely influenced. |
| Approach: | They propose to use a model editing method to modify specific examples in LMs to improve locality and reasoning capability by directing the hidden state of edit example towards spaces where semantics are sparse. |
| Outcome: | The proposed method improves locality and reasoning capability on two datasets. |

Editing Factual Knowledge in Language Models (2021.emnlp-main)
Copied to clipboard
| Challenge: | KnowledgeEditor can be used to edit factual knowledge stored in Language Models without the need for expensive retraining or fine-tuning. |
| Approach: | They propose a method which edits factual knowledge implicitly stored in Language Models and uses it to fix 'bugs' and 'obvious errors' they train a hyper-network with constrained optimization to modify a fact without affecting the rest of the knowledge; the hyper-netzwork is then used to predict the weight update at test time. |
| Outcome: | The proposed method can be used to edit factual knowledge without retraining or fine-tuning and can fix 'bugs' or unexpected predictions without the need for expensive re-training or meta-learning. |
