The Logit Refiner is introduced, a lightweight autoregressive module that restores intra-scale dependencies by sequentially sampling tokens conditioned on frozen backbone features and generalizes to text-to-image generation, confirming that the mean-field bottleneck persists across VAR variants and is effectively allev...
A novel notion of concept-wise mutual information is introduced and large, concept-dependent differences between individual layers are found, demonstrating that the generation of specific structures is localized in distinct parts of the network.
