### Task Definition

**Concept** is a generalization of the world in the process of cognition, which represents the shared features and essential characteristics of a class of entities.
Therefore, the endeavor of concept editing aims to modify the definition of concepts, thereby altering the behavior of LLMs when processing these concepts.


### Evaluation

To analyze conceptual knowledge modification, we adopt the  metrics for factual editing (the target is the concept $C$ rather than factual instance $t$).

- `Reliability`: the success rate of editing with a given editing description
- `Generalization`: the success rate of editing **within** the editing scope
- `Locality`: whether the model's output changes after editing for unrelated inputs


Concept Specific Evaluation Metrics

- `Instance Change`: capturing the intricacies of these instance-level changes
- `Concept Consistency`: the semantic similarity of generated concept definition


## 🌟 Usage

### 🎍 Current Implementation
As the main Table of our paper, four editing methods are supported for conceptual knowledge editing.
| **Method** |  GPT-2 | GPT-J | LlaMA2-13B-Chat | Mistral-7B-v0.1
| :--------------: | :--------------: | :--------------: | :--------------: | :--------------: | 
| FT | ✅ | ✅ | ✅ | ✅ | 
| ROME | ✅ | ✅ |✅ | ✅ | 
| MEMIT | ✅ | ✅ | ✅| ✅ | 
| PROMPT | ✅ | ✅ | ✅ | ✅ |


### 💻 Run
 You can follow [EasyEdit](https://github.com/zjunlp/EasyEdit/edit/main/examples/ConceptEdit.md) to run the experiments.
