This demo exemplifies a massively multilingual machine translation model's zero-shot capability to detect translation direction given two parallel texts as described in the paper "Machine Translation Models are Zero-Shot Detectors of Translation Direction" (linked above). |
|
|
|
Instructions: |
|
Simply input the parallel text in the respective languages and select the corresponding language for each text. The model will predict the direction of translation using the M2M100 418M translation model. |
