| Challenge: | pplx-embed uses diffusion-based pretraining to capture bidirectional context within passages. |
| Approach: | They propose a family of multilingual embedding models that leverage bidirectional attention through diffusion-based pretraining to capture bidirectional context within passages. |
| Outcome: | The proposed models achieve competitive performance on the MTEB(Multilingual, v2), MTEF(Code), BERGEN, and ToolRet retrieval benchmarks while pplx-embed-context-v1 sets new records on the ConTEB benchmark. |
