English(EN) Vectors from Larger Language Models Predict Human Reading Time and fMRI Data More Poorly when Dimensionality Expansion is Controlled

更大的LLM在预测人类认知数据方面显示出收益递减

发表在arXiv上的一项新研究表明,在控制维度扩展的情况下,更大的语言模型(LLMs)不一定会提高对人类阅读时间和fMRI数据的预测能力。研究发现,当模型规模增大时,已训练LLM相对于未训练同行的预测能力会显著下降,对于大多数数据集,在数十亿参数左右下降到零。这挑战了更大、更准确的LM本身就能更好地反映人类句子处理架构的观点。 AI

影响 表明简单地扩大LLM规模可能不会带来更好的人类认知模型,可能会转移研究重点。
