A research team is training a large multilingual language model on a dataset containing English, Spanish, and Swahili. They observe that after an extensive number of training steps, the model's performance on a Swahili translation task begins to degrade, even though its performance on English remains strong and the overall training loss continues to decrease. Which of the following concepts best explains this specific outcome?

Diagnosing Performance Degradation in a Multilingual Model

Addressing Performance Imbalance in a Multi-Language Model

Early Stopping in Multilingual Pre-training
