What is vit-base-patch32-384?
The vit-base-patch32-384 is a Vision Transformer model developed by Google that represents a significant advancement in computer vision. This model processes images by dividing them into 32x32 pixel patches and applies transformer architecture traditionally used in NLP to perform image classification tasks. The model was pre-trained on ImageNet-21k (14M images) and fine-tuned on ImageNet-1k at 384x384 resolution.
Implementation Details
This implementation features a BERT-like transformer encoder architecture specifically adapted for image processing. The model converts images into sequences of fixed-size patches, adds positional embeddings, and includes a special [CLS] token for classification tasks.
