Introducing FastViT: A Game-Changing Vision Transformer Architecture

Imagine a world where artificial intelligence (AI) models are not only accurate but also efficient. Thanks to the recent integration of transformer and convolutional designs, this is becoming a reality. One such breakthrough is FastViT, a hybrid vision transformer architecture that achieves the cutting-edge balance between accuracy and latency.

The Power of RepMixer: A Novel Token Mixing Operator

FastViT utilizes a groundbreaking building block called RepMixer. This operator leverages structural reparameterization to reduce the memory access cost by eliminating skip-connections in the network. By doing so, FastViT revolutionizes the efficiency of AI models.

Unmatched Performance: Speed and Accuracy Combined

What sets FastViT apart from other models is its outstanding speed without compromising accuracy. Through train-time overparametrization and large kernel convolutions, we enhance the model’s precision while keeping the latency minimal. In fact, FastViT triumphs over competitors, such as CMT, EfficientNet, and ConvNeXt, by achieving impressive speed gains of 3.5x, 4.9x, and 1.9x respectively on mobile devices. Moreover, it outperforms MobileOne with a remarkable 4.2% increase in Top-1 accuracy on the ImageNet dataset.

FastViT’s superiority extends beyond image classification. It excels in various tasks including detection, segmentation, and 3D mesh regression. Whether deployed on a mobile device or a desktop GPU, this architecture consistently delivers exceptional performance, significantly reducing latency.

Durability in the Face of Challenges

FastViT is not only swift and accurate, but it also exhibits remarkable resilience when confronted with out-of-distribution samples and corruptions. It surpasses competing robust models, making it an ideal choice for real-world applications where robustness is crucial.
