归一化轨迹模型实现精确似然训练，仅需几步

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员推出了一种新颖的生成模型方法——归一化轨迹模型（NTM），该方法在减少采样步数的情况下仍能保持精确似然训练。NTM在生成过程的每一步中集成了条件归一化流，从而实现表达性建模和端到端训练。该方法在文本到图像基准测试中仅使用四次采样步数即可达到具有竞争力或更优的性能，在保持似然框架完整性的同时显著提高了效率。 AI

影响 引入了一种更高效的具有精确似然的生成模型方法，有望加速图像生成并改进模型训练。

    归一化轨迹模型

    Diffusion-based models decompose sampling into many small Gaussian denoising steps -- an assumption that breaks down when generation is compressed to a few coarse transitions. Existing few-step methods address this through distillation, consistency training, or adversarial object…
