In this code-level talk, Julien will show you how to quickly build and deploy computer vision applications based on Transformer models. Along the way, you'll learn about the portfolio of open source and commercial Hugging Face solutions, and how they can help you deliver high-quality solutions faster than ever before.

3. 1998-2021 : Convolutional Neural Networks
Source: Wikipedia
CNNs extract features with learned filters.
A lot of pixels are discarded along the way.

4. 2021 : The Vision Transformer (Google)
"An Image is Worth 16x16 Words: Transformers for Image Recognition at Scale" https://arxiv.org/abs/2010.11929
ViT breaks an image into patches,
which are flattened and processed
as token sequences.
+ State-of-the-art accuracy
+ 4x less compute required for training
+ Transfer learning
