What is vit-large-patch32-384?
The Vision Transformer (ViT) Large Patch32-384 is a state-of-the-art transformer-based model designed for image classification tasks. It implements a BERT-like architecture that processes images as sequences of 32x32 pixel patches, with pre-training on ImageNet-21k (14M images) and fine-tuning on ImageNet 2012 at 384x384 resolution.
Implementation Details
This model processes images by dividing them into fixed-size patches of 32x32 pixels, which are linearly embedded along with position embeddings. A special [CLS] token is prepended to the sequence for classification tasks. The model operates at a high resolution of 384x384 pixels during fine-tuning, enabling detailed feature extraction.
- Pre-trained on ImageNet-21k with 14M images and 21,843 classes
- Fine-tuned on ImageNet 2012 with 1M images and 1,000 classes
- Uses normalized RGB channels (mean: 0.5, std: 0.5)
- Trained on TPUv3 hardware with 8 cores and 4096 batch size
Core Capabilities
- High-resolution image classification (384x384)
- Feature extraction for downstream tasks
- Support for transfer learning
- Robust performance on standard vision benchmarks
