A new approach for fine-tuning sentence transformers for intent classification and out-of-scope detection tasks (2024.emnlp-industry)
Copied to clipboard
| Challenge: | Virtual assistants often can handle only a limited scope of intents. |
| Approach: | They propose to combine out-of-scope (OOS) rejection with intent classification . they propose to regularize cross-entropy loss with an in-scope embedding reconstruction loss . |
| Outcome: | The proposed method achieves a 1-4% improvement in the area under the precision-recall curve for rejecting out-of-sample instances without compromising intent classification performance. |
