Improving Autoregressive Image Generation with Diffusion-Based Models
Challenges of Vector Quantization
Traditional autoregressive image generation models face challenges with vector quantization, leading to computational intensity and suboptimal image quality.
Novel Diffusion-Based Technique
A new technique developed by researchers from MIT CSAIL, Google DeepMind, and Tsinghua University eliminates the need for vector quantization. It leverages a diffusion process to model the per-token probability distribution within a continuous-valued space, significantly enhancing generation quality and efficiency.
Implementation of Diffusion Process
The technique uses a diffusion process to predict continuous-valued vectors for each token, resulting in substantial improvements in image generation quality and speed.
Performance and Results
Models using Diffusion Loss consistently achieve lower Fréchet Inception Distance (FID) and higher Inception Score (IS) compared to traditional methods, showcasing significant enhancement in image generation quality and speed.
Revolutionizing Image Generation
This innovative diffusion-based technique offers a groundbreaking solution to the challenge of dependency on vector quantization in autoregressive image generation, revolutionizing image generation and continuous-valued domains.
