  • TLDR:SpectralShift is proposed, a spectral reparameterization approach for long-context continual pretraining of GDNs that reparameterizes the alpha projections initialization to reshape the decay spectrum by enhancing slow propagation capacity, and further introduces a learning-rate scaling for alpha projections to facilitate long-context training.

  • TLDR中文:本文提出 SpectralShift,一种用于 GDN 长上下文持续预训练的谱重参数化方法,通过重参数化 alpha 投影的初始化以重塑衰减谱,增强慢传播能力,并进一步引入 alpha 投影的学习率缩放以促进长上下文训练。
