Mitigating Catastrophic Forgetting in Target Language Adaptation of LLMs via Source-Shielded Updates

This research focuses on a critical problem in adapting Large Language Models (LLMs) to new target languages: catastrophic forgetting. The proposed method, 'source-shielded updates,' aims to prevent the model from losing its knowledge of the original source language while learning the new target language. The paper likely details the methodology, experimental setup, and evaluation metrics used to assess the effectiveness of this approach. The use of 'source-shielded updates' suggests a strategy to protect the source language knowledge during the adaptation process, potentially involving techniques like selective updates or regularization.

• •Addresses the problem of catastrophic forgetting in LLM adaptation.
• •Proposes a method called 'source-shielded updates' to mitigate this issue.
• •Focuses on preserving source language knowledge during target language learning.
