What is vit-large-patch16-224?
The Vision Transformer (ViT) Large model is a sophisticated transformer-based architecture designed for image classification tasks. It processes images by dividing them into 16x16 pixel patches and treating these patches as tokens in a transformer sequence. The model was pre-trained on ImageNet-21k with 14 million images across 21,843 classes and fine-tuned on ImageNet-1K containing 1 million images across 1,000 classes.
Implementation Details
This implementation uses a large-scale transformer architecture that processes images at 224x224 resolution. The model employs a patch-based approach where images are divided into fixed-size patches (16x16 pixels) that are linearly embedded. A special [CLS] token is added at the sequence start for classification tasks, and absolute position embeddings are incorporated before processing through the transformer encoder.
