Brief information about ViT (Vision Transformer)
Vision Transformer (ViT) is an innovative neural network architecture that utilizes the Transformer architecture, primarily designed for natural language processing, in the domain of computer vision. Unlike traditional convolutional neural networks (CNNs), ViT employs self-attention mechanisms to process images in parallel, achieving state-of-the-art performance in various computer vision tasks.
The History of the Origin of ViT (Vision Transformer) and the First Mention of It
The Vision Transformer was first introduced by researchers from Google Brain in a paper titled “An Image is Worth 16×16 Words: Transformers for Image Recognition at Scale,” published in 2020. The research stemmed from the idea of adapting the Transformer architecture, originally created by Vaswani et al. in 2017 for text processing, to handle image data. The result was a groundbreaking shift in image recognition, leading to improved efficiency and accuracy.
Detailed Information about ViT (Vision Transformer): Expanding the Topic
ViT treats an image as a sequence of patches, similar to the way text is treated as a sequence of words in NLP. It divides the image into small fixed-size patches and linearly embeds them into a sequence of vectors. The model then processes these vectors using self-attention mechanisms and feed-forward networks, learning spatial relationships and complex patterns within the image.
Key Components:
- Patches: Images are divided into small patches (e.g., 16×16).
- Embeddings: Patches are converted into vectors through linear embeddings.
- Positional Encoding: Positional information is added to the vectors.
- Self-Attention Mechanism: The model attends to all parts of the image simultaneously.
- Feed-Forward Networks: These are utilized to process the attended vectors.
The Internal Structure of the ViT (Vision Transformer)
ViT’s structure consists of an initial patching and embedding layer followed by a series of Transformer blocks. Each block contains a multi-head self-attention layer and feed-forward neural networks.
- Input Layer: The image is divided into patches and embedded as vectors.
- Transformer Blocks: Multiple layers that include:
- Multi-Head Self-Attention
- Normalization
- Feed-Forward Neural Network
- Additional Normalization
- Output Layer: A final classification head.
Analysis of the Key Features of ViT (Vision Transformer)
- Parallel Processing: Unlike CNNs, ViT processes information simultaneously.
- Scalability: Works well with various image sizes.
- Generalization: Can be applied to different computer vision tasks.
- Data Efficiency: Requires extensive data for training.
