WAV: Multi-Resolution Block Residual Routing for Deep Decoder-Only Transformers
Researchers introduce WAV v1, a multi-resolution residual routing technique that improves deep transformer training by capturing directional detail in residual connections beyond simple block summaries. The method shows significant performance gains at 48-layer depths, reducing validation loss by 2.2% on TinyStories and 0.6% on Text8 with minimal parameter overhead.
