Multitask Prompted Training Enables Zero-Shot Task Generalization

Summary

This paper introduces a novel approach to zero-shot task generalization using multitask prompted training. The authors propose a method that leverages large language models and trains them on a diverse set of tasks, formulated as prompts. This multitask training strategy equips the model, named T0, with the ability to perform unseen tasks without any task-specific fine-tuning. The paper details the training procedure, highlighting the use of prompting to standardize inputs and outputs across various tasks, and evaluates T0's performance on a wide range of zero-shot benchmarks. The findings demonstrate that T0 achieves state-of-the-art results compared to existing zero-shot methods, exhibiting strong generalization capabilities and the ability to understand and adapt to new instructions. The core innovation lies in the synergy between multitask prompted training and the expressive power of large language models to enable robust zero-shot task transfer across diverse tasks.
