Hierarchical Transfer Learning for Multi-label Text Classification (P19-1)
Copied to clipboard
| Challenge: | Multi-Label Hierarchical Text Classification (MLHTC) is a task of categorizing documents into one or more topics organized in an hierarchical taxonomy. |
| Approach: | They propose a transfer learning based strategy where binary classifiers at lower levels are initialized using parameters of the parent classifier and fine-tuned on the child category classification task. |
| Outcome: | The proposed method improves on micro-F1 and macro-F1, respectively, compared to binary classifiers trained from scratch. |
