新的离散倾斜匹配方法微调掩码扩散大语言模型

研究人员推出了一种新颖的微调掩码扩散大语言模型(dLLMs)的方法,称为离散倾斜匹配(DTM)。DTM通过将dLLM微调重构为局部解掩码后验的状态级匹配,解决了强化学习中序列级边际似然的棘手问题。这种方法产生了一个可以明确最小化的加权交叉熵目标,并允许使用控制变量来提高训练稳定性。在合成迷宫规划任务上的实验以及与LLaDA-8B-Instruct的规模化评估表明,DTM在提高数独和Countdown等任务的性能方面非常有效,同时在数学基准测试上保持竞争力。 AI

影响 引入了一种新的训练技术,可以提高掩码扩散大语言模型在各种任务上的效率和性能。
