Understanding CV Transformers: A Comprehensive Guide

Transformers, as an attention-based encoder-decoder architecture, have not only revolutionized the field of Natural Language Processing (NLP) but have also made groundbreaking contributions to the field of Computer Vision (CV). Compared to Convolutional Neural Networks (CNNs), Vision Transformers (ViT) rely on excellent modeling capabilities, achieving outstanding performance on several benchmarks including ImageNet, COCO, and ADE20k.

As Atlas Wang, a computer scientist at the University of Texas at Austin, said:We have every reason to try using Transformers across the entire range of AI tasks.

Therefore, whether researchers in academia or professionals in the industry, it is essential to have a deep understanding of Transformer technology and to keep up with the cutting-edge research on Transformers to solidify their technical foundation.

AI is a field that is easy to get into, but hard to master, which is also why there has always been a significant shortage of high-end AI talent.

In your work:

Are you able to flexibly propose new models according to actual scenarios?

Or propose modifications to existing models?

In fact, these are core competencies and also thresholds that one must pass to become high-end talent. Although it is challenging, once you pass this threshold, you will find yourself in the TOP 5% of the market.

Therefore, we have designed this course with one goal: to give you the opportunity to become part of the TOP 5% in the market. In this course, we will explain the principles, implementation methods, and application techniques of Transformers in the CV field in a step-by-step manner. During the learning process, you can expand your thinking through practical projects, integrating knowledge to genuinely enhance your problem-solving abilities.

Project Introduction
Project 1: Image Recognition System Based on ViT Model
Project Description: As a classic application case of Transformers in the visual domain, the ViT model was the first to apply the Transformer ideas from the NLP field to the image field, providing excellent inspiration for a series of subsequent Transformer in Vision design works. We will use the ViT model for image classification tasks as an example to embark on a journey of applying Transformer ideas to the visual field.
Algorithms Used in the Project:
ViT model
Cross-entropy loss
Multi-label/multi-class classification
Self-attention
LSTM/GRU
Tools Used in the Project:
Python
pytorch
OpenCV
ViT
Expected Results of the Project:
  1. Students will first implement the ViT model themselves and test the results on the dataset. They will then compare with the official implementation, and if there are significant differences, they will need to investigate the reasons.
  2. Students will master how to apply the token and self-attention concepts from Transformers to the image domain. By understanding the principles, students should be able to apply Transformer ideas to other related problems.
  3. Students will learn the training methods for ViT, running through the entire pipeline from data preparation, model training, parameter tuning, to model testing and metric calculation.

Project 2: Image Classification and Object Detection Tasks Based on SwinTransformer Model
Project Description: In the previous project, we learned about the ViT model, a successful visual Transformer model that applies Transformers to visual classification problems. However, the design of the ViT model is somewhat singular and has some shortcomings, especially regarding issues present in images, such as scale transformation problems that are not well addressed, and efficiency concerns that are not considered. In this project, we will study another advanced visual Transformer model: the SwinTransformer model.
Algorithms Used in the Project:
SwinTransformer
Cross-Entropy Loss
Regression Loss
Forward-Backward Propagation
Tools Used in the Project:
Python
pytorch
OpenCV
Expected Results of the Project:
  1. Students will implement the SwinTransformer code themselves (or refer to the official implementation) and optimize their implementation based on the official one. If there are significant differences in experimental results, students will need to investigate the reasons.
  2. Students will appreciate the idea of using SwinTransformer for object detection.
  3. Students will master how to optimize the implementation of the self-attention mechanism of SwinTransformer from local to global perspectives.
  4. Students will learn how to apply Transformer ideas to their actual work or study-related problems.
