New Generative Refinement Networks advance visual synthesis benchmarks

Researchers have introduced Generative Refinement Networks (GRN), a novel visual synthesis paradigm designed to overcome the computational inefficiencies of diffusion models and the limitations of autoregressive models. GRN utilizes Hierarchical Binary Quantization (HBQ) for near-lossless discrete tokenization and incorporates a global refinement mechanism for progressive image correction, akin to a human artist. An entropy-guided sampling strategy allows for complexity-aware generation without sacrificing visual quality. GRN has set new benchmarks on ImageNet for image reconstruction and class-conditional generation, and shows promise in text-to-image and text-to-video synthesis. AI
