Deutsch(DE) Richness Is Not Evenness: Ordered Renyi Crossings under Self-Training

GPT-2 自训练改变词语主导地位和熵分布

研究人员探索了递归自训练对语言模型的影响,特别是对 GPT-2 模型在其自身输出上进行多代微调。他们观察到,随着训练温度的升高,信息熵的不同度量(如最小熵和碰撞熵)在不同的温度点上从损失转变为增益。这个过程导致独特词语类型的数量减少,同时降低了最常用词语的主导地位。研究发现,这种熵变化的排序在各种设置下是一致的,包括不同的度量采样器、词语预算,甚至在对人类文本进行微调时也是如此,这表明熵分布应与独立的质量度量一起报告。 AI

影响 这项研究深入探讨了自训练如何影响语言模型的词汇和词语主导地位,可能为未来的训练方法提供参考。
