摘要:

GPT-3.5模型在各种自然语言处理(NLP)任务中表现出令人印象深刻的性能,展示了其强大的理解和推理能力。然而,它们的鲁棒性和处理开放世界各种复杂性的能力还有待探索,这在评估模型的稳定性方面尤其重要,也是值得信赖的人工智能的一个关键方面。在这项研究中,我们对GPT-3.5进行了全面的实验分析,使用21个数据集(约116 K测试样本)探索其鲁棒性,其中包含TextFlint的66个文本转换,涵盖9个流行的自然语言理解(NLU)任务。我们的研究结果表明,虽然GPT-3.5在某些任务上优于现有的微调模型,但它仍然遇到了显着的鲁棒性下降,例如其在自然语言推理和情感分析任务中的平均性能分别下降了35.74%和43.59%。我们还表明,GPT-3.5面临着一些具体的鲁棒性挑战,包括鲁棒性不稳定性,提示敏感性和数字敏感性。这些见解对于理解其局限性和指导未来的研究以解决这些挑战以提高GPT-3.5的整体性能和泛化能力是有价值的。

英文摘要:

The GPT-3.5 models have demonstrated impressive performance in various Natural Language Processing (NLP) tasks, showcasing their strong understanding and reasoning capabilities. However, their robustness and abilities to handle various complexities of the open world have yet to be explored, which is especially crucial in assessing the stability of models and is a key aspect of trustworthy AI. In this study, we perform a comprehensive experimental analysis of GPT-3.5, exploring its robustness using 21 datasets (about 116K test samples) with 66 text transformations from TextFlint that cover 9 popular Natural Language Understanding (NLU) tasks. Our findings indicate that while GPT-3.5 outperforms existing fine-tuned models on some tasks, it still encounters significant robustness degradation, such as its average performance dropping by up to 35.74\% and 43.59\% in natural language inference and sentiment analysis tasks, respectively. We also show that GPT-3.5 faces some specific robustness challenges, including robustness instability, prompt sensitivity, and number sensitivity. These insights are valuable for understanding its limitations and guiding future research in addressing these challenges to enhance GPT-3.5's overall performance and generalization abilities.
