Transformer优化新见解:识别出隐藏边界运动

研究人员在Transformer优化中识别出一种称为“隐藏边界运动”的现象,其中权重和偏差更新对于具有非零均值输入的仿射层在函数上是无法区分的。这种运动主要通过权重矩阵更新而非显式偏差更新来实现,对优化有显著影响。开发了一种名为SBO-AdamW的新型优化器来解决这个问题,在IMDb数据集的验证准确率上有所提高,但仍需要进一步工作才能实现稳定、通用的解决方案。 AI

影响 识别出Transformer中一种新的优化机制,可能带来更高效的训练和改进的模型性能。

    Transformer优化中的隐藏边界运动:仿射权重和偏置更新的函数空间正交化

    arXiv:2607.22927v1 Announce Type: new Abstract: Weights and biases are normally optimized as separate parameter tensors, yet they do not represent separate functions when the input to an affine layer has nonzero mean. For an affine map $z=Wx+b$ with input mean $\mu$, a weight upd…
