| Challenge: | Existing methods for Hierarchical Text Classification (HTC) are expensive and require explicit injection of the hierarchy, verbalizers, and/or prompt engineering. |
| Approach: | They propose a hierarchical text classification system that uses a single classifier to predict one or more topics using differentiable prompts and labels that are learnt through backpropagation. |
| Outcome: | The proposed model outperforms existing models on several benchmarks that span a range of topics consistently. |
