Abstract: Systems and methods are provided for vector-quantized image modeling using vision transformers and improved codebook handling. In particular, the present disclosure provides a Vector-quantized Image Modeling (VIM) approach that involves pre-training a machine learning model (e.g., Transformer model) to predict rasterized image tokens autoregressively. The discrete image tokens can be encoded from a learned Vision-Transformer-based VQGAN (example implementations of which can be referred to as ViT-VQGAN). The present disclosure proposes multiple improvements over vanilla VQGAN from architecture to codebook learning, yielding better efficiency and reconstruction fidelity. The improved ViT-VQGAN further improves vector-quantized image modeling tasks, including unconditional image generation, conditioned image generation (e.g., class-conditioned image generation), and unsupervised representation learning.

The antioxidant peptides are produced from cereal grain protein sources, which provide a number of advantages over more expensive antioxidant sources and synthetically-produced antioxidants. The antioxidant peptides are produced by reacting the cereal grain material with an enzyme capable of hydrolyzing proteins within the material, thereby forming hydrolysate peptides. The hydrolysate peptides are then selectively recovered to form an antioxidant peptide product. The antioxidant peptide product is useful in a number of applications, particularly as an ingredient in a food product to provide antioxidant properties to the food product.
