Researchers have introduced SpectralShift, a novel method for extending the context window of Gated DeltaNet (GDN) models, which utilize linear attention layers. This approach focuses on the spectral properties of the transition matrix, identifying that a broad slow spectral band and the preservation of fast-decaying modes are crucial for effective long-range information retrieval and context switching. SpectralShift reparameterizes alpha projections to enhance slow propagation capacity and employs learning-rate scaling for alpha projections to facilitate training. Experiments demonstrate that SpectralShift significantly improves the long-context capabilities of GDNs, offering an efficient solution for extending their context windows. AI
