| Challenge: | SCOOS leverages semantic cues embedded in class labels to improve classification accuracy. |
| Approach: | They propose a method to create a compact feature space around class label semantics . they use a shared latent space between ID features and class names to minimize losses . |
| Outcome: | The proposed method outperforms existing methods for out-of-scope intent detection and ID intent classification. |
Refinement Matters: Textual Description Needs to be Refined for Zero-shot Learning (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Zero-Shot Learning (ZSL) is a new form of learning that uses textual description and attribute to transfer knowledge from seen to unseen classes. |
| Approach: | They propose a non-generative gating-based attribute refinement network for ZSL that uses a circle loss-guided attribute embedder to refine the attributes. |
| Outcome: | The proposed approach outperforms generative methods and most generative ones in all three scenarios. |
