To address this challenge, researchers have developed parameter-efficient methods that balance performance and resource cost. However, these methods often come with trade-offs like increased inference latency, token length usage, or limited adaptability for multitasking scenarios.

This method significantly enhances the performance of the model on new tasks. Its versatility in model structure also enables its application to various Transformer-based models.",
