What is vit_base_patch32_224.augreg_in21k_ft_in1k?

This is a Vision Transformer (ViT) model specifically designed for image classification tasks. Initially trained on the extensive ImageNet-21k dataset and subsequently fine-tuned on ImageNet-1k, this model incorporates advanced augmentation and regularization techniques. Originally implemented in JAX by the paper authors and later ported to PyTorch by Ross Wightman, it represents a sophisticated approach to computer vision tasks.

Implementation Details

The model employs a patch-based approach to image processing, dividing input images into 32x32 patches. With 88.2M parameters and 4.4 GMACs, it strikes a balance between computational efficiency and performance. The architecture processes 224x224 pixel images and generates 4.2M activations during operation.

  • Pretrained on ImageNet-21k for robust feature extraction
  • Fine-tuned on ImageNet-1k with augmentation
  • Implements the transformer architecture for vision tasks
  • Supports both classification and embedding extraction
