Logit Refiner enhances visual autoregressive models by restoring intra-scale dependencies

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method called the "Logit Refiner" to improve the quality of images generated by Visual Autoregressive Models (VAR). This technique addresses a limitation in VARs where parallel decoding discards spatial dependencies between tokens within the same scale, leading to less coherent images. The Logit Refiner is a lightweight module that restores these intra-scale dependencies by sequentially sampling tokens, enhancing generation quality without requiring retraining or significant increases in parameters or compute. This approach has shown consistent improvements across various VAR models and generalizes to text-to-image generation. AI

IMPACT This method offers a way to improve image generation quality in existing models with minimal overhead.

    Logit Refiner: Improving Visual Autoregressive Models via Intra-Scale Dependency Modeling

    arXiv:2609.11804v1 Announce Type: cross Abstract: Visual Autoregressive Models (VAR) generate images through next-scale prediction, producing all tokens within each scale in parallel. We show that this parallel decoding constitutes a mean-field-style approximation that discards s…
