AI模型训练:更多数据,而非仅仅是规模,驱动性能提升

一项最新分析探讨了AI开发中模型规模(参数)和训练数据(token)之间的最佳平衡。与早期认为更大模型总是更优的观点相反,DeepMind的Chinchilla论文在2022年展示了一个拥有700亿参数的模型,通过训练更多数据,其表现优于一个拥有2800亿参数的模型。这表明那个时代许多大型模型训练不足,更有效的方法是按比例扩展参数和token。作者通过在笔记本电脑上训练小型模型进一步验证了这一点,表明即使在较小的规模下,对于固定的计算预算,一个训练了更多数据的模型也比一个数据量较少但规模更大的模型取得了更好的结果。 AI

影响 建议AI训练方法论的转变,将数据量与模型规模并重,以实现最佳性能。
