摘要:

我们提出了HyperLoader,这是一种在多任务环境中结合不同参数高效微调方法的简单方法。为实现该目标,我们的模型利用超网络,基于任务、transformer层及其在该层内的位置来生成这些模块的权重。我们的方法结合了多任务学习的优势,通过捕获所有任务的结构,同时通过将任务特定知识封装在生成的权重中来缓解任务干扰问题,并具备结合不同参数高效方法以超越全量微调的优势。我们提供了实证证据,表明HyperLoader在大多数数据集上优于先前方法,并在高资源和低资源场景下均获得了跨任务的最佳平均性能。

英文摘要:

We present HyperLoader, a simple approach that combines different parameter-efficient fine-tuning methods in a multi-task setting. To achieve this goal, our model uses a hypernetwork to generate the weights of these modules based on the task, the transformer layer, and its position within this layer. Our method combines the benefits of multi-task learning by capturing the structure of all tasks while reducing the task interference problem by encapsulating the task-specific knowledge in the generated weights and the benefits of combining different parameter-efficient methods to outperform full-fine tuning. We provide empirical evidence that HyperLoader outperforms previous approaches in most datasets and obtains the best average performance across tasks in high-resource and low-resource scenarios.
