The Spectral Lifecycle of Transformer Training: Transient Compression Waves, Persistent Spectral Gradients, and the Q/K--V Asymmetry
★★★★★
significance 3/5
This research presents a systematic study of how weight matrix singular value spectra evolve during the pretraining of transformer models. The authors identify transient compression waves and persistent spectral gradients, establishing a two-timescale dynamical model to explain how rank and spectral shape encode information during training.
Why it matters
Understanding these spectral dynamics provides a mathematical framework for optimizing transformer architecture and predicting training stability during large-scale pretraining.
