新的球形布朗扩散方法增强语言模型

研究人员引入了球形布朗扩散(Spherical Brownian Diffusion),一种用于连续扩散语言模型的新方法,该方法利用单位球面上的布朗运动。该方法提供了一个有原则的前向过程,具有加性噪声时钟和精确的祖先桥接,并辅以学习到的干净标记后验,以实现多样化的采样器。研究表明,采样器的选择对性能有显著影响,在推理任务上产生25.0个点的差异,而当使用矩匹配的vMF腐败时,腐败过程本身的影响较小。分类细化提高了推理任务的性能,而无条件文本生成则受益于保持多样性的随机更新。 AI

影响 引入了一种新颖的语言模型扩散过程,有望提高推理和生成任务的性能。

    Spherical Brownian Diffusion for Language Modeling

    arXiv:2610.35101v1 Announce Type: new Abstract: Continuous diffusion language models involve two coupled design choices: how to corrupt continuous token representations and how to invert that corruption at generation time. Recent work has explored language generation on the unit …
