How Transformers Finally Ate Vision – Isaac Robinson, Roboflow
Overview
This talk explores the evolution of computer vision models, detailing how transformers, despite lacking inherent inductive biases for vision, ultimately surpassed traditional convolutional neural networks (CNNs). This shift was driven by massive, specialized pre-training techniques and leveraged infrastructure advancements from large language models, enabling transformers to learn visual patterns effectively.
Who should watch
- AI engineers and researchers interested in the evolution of vision models.
- Builders and product managers evaluating backbone architectures for vision tasks.
- Anyone curious about the interplay between architecture, pre-training, and performance in deep learning.
- Those facing challenges with deploying large, inflexible foundation models in resource-constrained environments.
Key takeaways
- Convolutional Neural Networks (CNNs) initially excelled due to strong inductive biases, mimicking biological vision.
- Vision Transformers (ViTs) emerged with no inherent visual bias, relying on a set-to-set operation with quadratic compute scaling.
- Despite initial disadvantages, ViTs achieved superior performance through massive, specialized pre-training (e.g., Masked Autoencoders, DINOv2/v3) and by adopting speedups from LLM infrastructure like FlashAttention.
- Architectural variations like Swin Transformers and ConvNeXt attempted to reintroduce inductive biases or combine CNN and transformer principles, but ultimately, heavily pre-trained ViTs proved dominant.
- Foundation models like SAM demonstrate the trend, with later versions relying on ViT backbones trained with techniques like MAE.
- The reliance on large-scale pre-training creates challenges for deployment flexibility and efficiency, leading to large, slow models.
- New approaches combine advanced pre-training with neural architecture search and deployment-focused methods to create families of high-performance, adaptable models.
- *Massive VIT-specific pre-training plus speed ups from LLMs plus pre-training compatible neural architecture search* enables flexible deployment.
Notable quotes
The argument is that it is because of massive VIT-specific pretraining, and then we get to borrow a lot of speedups and infrastructure from the fact that LLMs are blowing up.
