Copied to clipboard
| Challenge: | rumor detection models often assume a simplistic one-to-one alignment between modalities . authors present a method that preserves hierarchical, non-linear relationships . |
| Approach: | They propose a method that uses hyperbolic geometry to preserve hierarchical relationships . it decomposes image and text content into three levels and embeds them in hyperbolical space . |
| Outcome: | The proposed method preserves hierarchical relationships rather than representing them at a flat semantic level. |
