Recent Advances in Image Generation
In recent years, image generation has transformed significantly thanks to new models like Latent Diffusion Models (LDMs) and Mask Image Models (MIMs). These tools simplify images into manageable forms known as low-dimensional latent space, allowing for the creation of highly realistic images.
The Challenge of Autoregressive Models
While autoregressive generative models have excelled in natural language processing (NLP), they have not yet matched this success in image generation. Even though they share the same latent space as models like LDMs and MIMs, they still have their challenges.
Introduction of DiGIT
A new method named Discriminative Generative Image Transformer (DiGIT) has been introduced to improve these models. Developed by researchers from various universities, DiGIT innovatively separates the training of encoders and decoders. This improves stability in the latent space, making the model more effective for generating images.
How DiGIT Works
DiGIT uses a K-means clustering technique to convert the encoder’s latent features into discrete tokens. By utilizing these tokens, a causal Transformer predicts the next token, leading to improved performance in image generation.
Key Contributions
- Offers a clear understanding of the link between latent space and generative models, emphasizing the need for stable latent spaces.
- Introduces an effective training method that enhances the functionality of image autoregressive models.
- Presents a discrete image tokenizer that significantly boosts model performance.
Conclusion
This research challenges the idea that excellent reconstruction guarantees effective latent space for autoregressive models. The insights gained from this work are aimed at inspiring renewed interest in generative pre-training of image models and augmenting technological advancements in this area.
