What is dinov2-large?
DINOv2-large is a sophisticated Vision Transformer (ViT) model developed by Facebook Research for self-supervised image understanding. With 304M parameters, it represents a large-scale implementation of the DINO (self-DIstillation with NO labels) architecture, designed to learn robust visual features without requiring supervised training.
Implementation Details
The model processes images by dividing them into fixed-size patches and employs a transformer encoder architecture similar to BERT. It includes a special [CLS] token for classification tasks and utilizes absolute position embeddings. The model operates using F32 tensor types and is implemented in PyTorch with Safetensors support.
