Vision models and their unique challenges#
While LLMs focus on text, LVMs specialize in processing and understanding visual information. This presents a unique set of challenges and opportunities.
The following are some key challenges in vision modeling:
Handling high-dimensional input: Images and videos contain far more raw data than text, requiring efficient processing techniques.
Understanding spatial relationships: Vision models must grasp how objects relate in
space Space refers to the three-dimensional physical environment where objects exist and interact relative to each other. Dealing with variability: This is a challenge because changes in lighting, angle, occlusion, and other factors can alter the appearance of objects, making it difficult for vision models to consistently recognize and interpret them accurately. This variability requires models to generalize well across diverse visual conditions to maintain reliable performance.
Bridging the semantic gap: Translating pixel-level information into high-level semantic understanding.
Convergence of language and vision in AI#
While LLMs and LVMs have traditionally been separate domains, recent advancements have led to increasing convergence between language and vision in AI systems. This trend is driven by the recognition that human intelligence seamlessly integrates multiple modalities, including vision and language.
Some key developments in this convergence include:

2. Transfer learning and pretraining#
Transfer learning and pretraining are crucial techniques that allow LVMs to utilize knowledge gained from one task or dataset to improve performance on others.
Key aspects of transfer learning and pretraining in LVMs include:
Large-scale pretraining: Models are initially trained on massive datasets of diverse images, learning general visual features.
Fine-tuning: Pretrained models are then adapted to specific tasks or domains with smaller, specialized datasets.
Domain adaptation: Techniques to apply models trained on one visual domain (e.g., natural images) to another (e.g., medical imaging).
3. Zero-shot and few-shot learning#
One of the most impressive capabilities of modern LVMs is their ability to perform well on new tasks with little or no specific training data, known as zero-shot and few-shot learning.
Key aspects of zero-shot and few-shot learning in LVMs include:
Zero-shot learning: Recognizing or classifying objects or concepts not seen during training.
Few-shot learning: Quickly adapting to new tasks with only a few examples.

Building upon our understanding of the key features that define LVMs, let’s explore some of the field’s most influential and innovative implementations. These LVMs represent the cutting edge of visual AI, each with its unique strengths and applications.
The prominent LVMs#
The field of LVMs is diverse and rapidly evolving. Here, we’ll examine some of the most significant models that have substantially impacted visual AI. In detail, we will discuss three models (CLIP, ViT, and DINOv2) and provide a comparative analysis of others, including these three LVMs.
CLIP (Contrastive Language–Image Pre-training)#
CLIP (Contrastive Language–Image Pre-training) is a model introduced by OpenAI that aims to learn a wide range of visual concepts from natural language descriptions. By training on various internet data, CLIP can understand and generate responses to various images and text descriptions without requiring fine-tuning for specific tasks. This approach allows CLIP to perform various tasks, such as image classification, object detection, and more, directly from textual descriptions.
How does CLIP work?#
The core mechanism of CLIP involves the alignment of images and their corresponding text descriptions through a contrastive learning objective. The model learns to distinguish between matching and nonmatching image-text pairs by projecting them into a shared embedding space. Let’s break down the process step by step:
Input data preparation
Encoding the data
Calculating similarity scores
Contrastive learning objective
Zero-shot learning capability
The CLIP workflow (Source: Alec Radford, Learning Transferable Visual Models From Natural Language Supervision)
Now, let’s discuss each step in more detail.
1. Input data preparation#
Text descriptions: The model receives various text descriptions. For example, in the attached image, we see text like “Pepper the Aussie pup” and generic placeholders like “A photo of an {object}.”
Images: A diverse set of images corresponding to the text descriptions. The images might be of dogs, cars, planes, etc.
2. Encoding the data#
Text encoder: Each text description is passed through a text encoder, transforming it into a vector representation. This encoding captures the semantic meaning of the text.
Image encoder: Each image is passed through an image encoder, which converts it into a corresponding vector representation. This encoding captures the visual features of the image.
3. Calculating similarity scores#
The encoded vectors from both the text and image encoders are then compared in a joint embedding space.
A similarity score is computed for each pair of text and image encodings, typically using a dot product. These scores form a similarity matrix where each cell represents the similarity between a particular image and text pair.
4. Contrastive learning objective#
Positive pairs: The model maximizes the similarity for matching image-text pairs (e.g., an image of a dog and the text “a photo of a dog”).
Negative pairs: The model minimizes the similarity for non-matching pairs (e.g., an image of a car and the text “a photo of a dog”).
This objective encourages the model to project matching pairs closer together in the embedding space while pushing non-matching pairs further apart.
5. Zero-shot learning capability#
Once trained, CLIP can generalize to various downstream tasks without requiring additional fine-tuning.
For instance, given a new image and a set of potential text descriptions, CLIP can identify the most likely description by selecting the one with the highest similarity score.
CLIP represents a significant advancement in machine learning by leveraging natural language supervision to learn visual concepts. Its ability to perform zero-shot learning across various tasks without requiring task-specific fine-tuning makes it a versatile tool for various applications. Combining text and image encoders allows CLIP to understand and generate accurate responses, demonstrating the power of aligning visual and textual information in a shared embedding space.
Vision Transformer (ViT)#
Vision Transformer (ViT) is a novel architecture designed to process images using a transformer-based approach, traditionally used for natural language processing tasks. In the paper by Dosovitskiy et al., "An Image is Worth 16x16 Words: Transformers for Image Recognition at Scale," ViT leverages the power of transformers to achieve remarkable results in image recognition tasks, often surpassing conventional convolutional neural networks (CNNs).
How does ViT work?#
ViT processes images in the following steps:
Image to patches
Linear projection of flattened patches
Position embeddings
Transformer encoder
Class token
MLP head
The Vision Transformer (ViT) workflow (Source: Alexey Dosovitskiy, An Image is Worth 16x16 Words: Transformers for Image Recognition at Scale)
Now, let’s discuss each step in more detail.
1. Image to patches#
The input image is divided into fixed-sized nonoverlapping patches, typically 16×16 pixels. For example, an image with dimensions 224×224 pixels would be split into 196 patches (14×14). Each patch is then flattened into a single vector.
2. Linear projection of flattened patches#
Each 16×16 patch is flattened into a vector of size 256, assuming each pixel is treated as a feature. These flattened vectors are then linearly transformed into fixed-sized embeddings, creating a sequence of patch embeddings.
3. Position embeddings#
Positional embeddings are added to each patch embedding to incorporate positional information and help the model understand spatial relationships between patches. This ensures the positional context of the patches within the image is retained.
4. Transformer encoder#
The sequence of embedded patches, along with a special learnable [class] embedding, is fed into a transformer encoder.
The transformer encoder consists of multiple layers (L layers), each comprising Multi-head attention, MLP blocks, and normalization layers.
Multi-head attention:
Computes attention scores between all pairs of patches, allowing the model to focus on different parts of the image.
Produces a weighted sum of the values (patch embeddings), enabling the model to learn complex relationships.
Normalization layers:
Applied before and after the multi-head attention and MLP blocks to stabilize and regularize the training.
MLP (Multilayer perceptron):
Consists of fully connected layers with activation functions.
Processes the embeddings to capture more complex patterns.
5. Class token#
The special learnable [class] embedding aggregates information from all patch embeddings. It interacts with the patch embeddings through the transformer layers, capturing a holistic representation of the entire image.
6. MLP head#
The output corresponding to the [class] token is passed through an MLP head, which produces the final classification output, predicting the class of the input image (e.g., bird, ball, car, etc.).
ViT represents a significant shift from traditional CNN-based image recognition approaches. It utilizes the power of transformers to achieve state-of-the-art results. By treating images as sequences of patches and leveraging transformer encoders, ViT demonstrates the versatility and effectiveness of transformers beyond natural language processing tasks.
What is DINOv2?#
DINOv2 (distillation with no labels) is a framework designed to learn robust visual features without supervision. The core idea behind DINOv2 is to train a vision transformer model to understand and represent visual data in a way that can be generalized across different tasks without the need for explicit labels during training. This makes DINOv2 particularly powerful for scenarios where labeled data is scarce or unavailable.
How does DINOv2 work?#
DINOv2 operates through several key steps, which are illustrated in the following workflow diagrams:
The DINOv2 workflow (Source: Maxime Oquab, DINOv2: Learning Robust Visual Features without Supervision)
1. Data collection#
DINOv2 begins with a large set of uncurated data alongside a smaller, curated dataset. The uncurated data is typically vast and unlabeled, while the curated data is smaller but more controlled and labeled.
2. Embedding#
Both uncurated and curated datasets are passed through an embedding process. This step transforms the visual data into a dense vector representation using a neural network. This embedding helps the model understand and differentiate between different visual features present in the images.
3. Deduplication#
The embedding vectors are then subjected to a deduplication process. Here, duplicate or highly similar embeddings are identified and removed to ensure that the training data is diverse and free from redundancy. This step is crucial for improving the efficiency and effectiveness of the learning process.
4. Retrieval#
After deduplication, the embeddings from the uncurated dataset are compared with those of the curated dataset. The model retrieves the most relevant embeddings from the uncurated dataset that match the characteristics of the curated dataset. This retrieval process augments the curated data with additional relevant examples from the uncurated data.
5. Augmented curated data#
The retrieved embeddings are added to the curated dataset, resulting in an augmented curated dataset. This augmented dataset now contains more diverse and relevant examples, enhancing the model’s ability to learn robust visual features.
DINOv2 represents a significant advancement in learning visual features without supervision. By leveraging large uncurated datasets and a robust deduplication and retrieval process, DINOv2 creates an augmented dataset that enhances the model’s ability to generalize across various tasks. This makes DINOv2 a powerful tool for scenarios where labeled data is limited or unavailable, paving the way for more robust and efficient visual understanding models.
