OPPO开源Diffusion多语言适配器—— MultilingualSD3-adapter 和 ChineseFL
https://i-blog.csdnimg.cn/direct/f3ecdee8791c4424be265f4b334a6955.pngMultilingualSD3-adapter 是为 SD3 量身定制的多语言适配器。 它源自 ECCV 2024 的一篇题为 PEA-Diffusion 的论文。ChineseFLUX.1-adapter是为Flux.1系列机型量身定制的多语言适配器，理论上继续了ByT5，可支持100多种语言，但在中文方面做了额外优化。 它源于一篇题为 PEA-Diffusion 的 ECCV 2024 论文。

PEA-Diffusion
作者首先提到了一种名为 “知识蒸馏”（Knowledge Distillation，KD）的方法。KD 是一个过程，在这个过程中，一个较小的机器学习模型（称为学生）会学习模仿一个较大、较复杂的模型（称为西席）。在这种情况下，目的是让学生模型尽可能接近西席的输出或预测。这被称为 “逼迫学生分布与西席分布相匹配”。
然而，作者还盼望确保西席模型和学生模型不仅能产生相似的输出效果，而且能以相似的方式处理信息。这就是特征对齐的作用所在。他们盼望西席模型和学生模型的中间计算或特征图也能相似。因此，他们引入了一种技术，在这些模型的中间层增强这种特征对齐。如许做的目的是减少所谓的分布偏移，使学生模型更像西席模型。
现在，当模型之间存在维度差异时，OPPOer/ChineseFLUX.1-adapter 就会发挥作用。在这种情况下，他们使用的是名为 CLIP（对比语言图像预练习）的模型，一个用于英语数据，一个用于非英语数据。适配器是添加到模型中的一个小型附加组件，用于对齐或转换特征（中间计算）以匹配维度。该适配器颠末练习，可以学习特定语言的信息，而且设计高效，只有 600 万个参数。
因此，总的来说，OPPOer/ChineseFLUX.1-adapter 是一种用于调整不同模型（在本例中为英语和非英语 CLIP 模型）中特征维度的技术，以促进知识提炼并进步学生模型的性能。它是这个复杂系统中一个小而紧张的组成部分！
