11.3 Transformer Models for Multimodal Tasks
The use of Transformer models has mainly been focused on Natural Language Processing (NLP). However, there is so much more to it than just NLP. Lately, researchers have been exploring the potential of Transformer models in multimodal tasks. These tasks require the processing of both text and non-text data, such as images and audio.
When we say "multimodal," we're referring to the use of multiple types or modes of data. For example, a social media platform that analyzes both the visual and textual content of a post is a great example of a multimodal application. This can be used for various purposes, including image captioning and visual question answering.
One of the main advantages of using Transformers for multimodal tasks is their ability to model complex relationships between different types of data. For instance, in image captioning, a Transformer model can learn the correspondence between the pixels in the image and the words in the caption. This makes it possible to extract meaningful information from different types of data and use it to make more accurate predictions.
11.3.1 ViT (Vision Transformer)
ViT is one example of extending Transformer models to non-textual data. Instead of convolutions, attention is used as the main operation for processing images. ViT treats an image as a sequence of patches and applies a Transformer model to this sequence.
The ViT (Vision Transformer) model is an excellent example of how Transformer models can be extended to non-textual data. In this case, attention is used as the primary operation for processing images, as opposed to convolutions. This model treats an image as a sequence of patches that are then processed by a Transformer model.
By using patches, the model can detect more intricate details in an image, such as the edges of objects, the colors of the pixels, and the distribution of the various features in the image. This approach allows the model to better understand the image and make more accurate predictions based on the data presented.
Additionally, by applying the Transformer model to images, we can leverage the power of this model to a new type of data, which opens up new possibilities for research and development in the field of machine learning and computer vision.
Example:
Here is a basic example of using the Vision Transformer model for image classification using the timm library:
import torch
import timm
# Load the ViT model
model_name = 'vit_base_patch16_224'
model = timm.create_model(model_name, pretrained=True)
# Assume we have a batch of images 'images'
# images shape should be (batch_size, 3, height, width)
# for ViT, height and width should be at least 224
images = torch.rand((4, 3, 224, 224))
# Get the model prediction
outputs = model(images)
# The output is the raw scores for each class in the model
print(outputs.shape) # Should be (4, num_classes)11.3.2 CLIP (Contrastive Language-Image Pretraining)
CLIP also from OpenAI, is an example of a multimodal Transformer model. It is designed to understand information from both images and text, making it possible to perform zero-shot tasks that rely on both types of data. For example, CLIP can be used to find images that best match a given text description or vice versa.
CLIP developed by OpenAI, is a state-of-the-art multimodal Transformer model that was recently introduced. With the ability to process both images and text, CLIP is capable of performing zero-shot tasks that rely on both types of data, which is a significant breakthrough in AI technology.
This means that, using CLIP, you can easily retrieve images that best match a given text description or vice versa, without the need for additional training or supervision. This makes it particularly useful for applications such as image and text search, content tagging, and recommendation systems, among others. The potential uses for CLIP are numerous, and it is expected to have a significant impact on the field of computer vision and natural language processing in the near future.
In the future, we expect to see Transformer models applied to a wider variety of multimodal tasks, as they continue to redefine the boundaries of what's possible with machine learning models. This opens up an exciting area of research that further leverages the powerful capabilities of the Transformer architecture in tackling complex, real-world problems.
