Hiera: A Hierarchical Vision Transformer without the Bells-and-Whistles
In the rapidly evolving landscape of artificial intelligence, a groundbreaking approach to supervised classification performance has been born. Modern hierarchical vision transformers have been known to incorporate various vision-specific components, aiming to enhance accuracies and produce desirable FLOP counts. However, these augmentations have led to slower processing times compared to their vanilla ViT counterparts. In this exciting research, we challenge the necessity of such additional complexities.
Enter Hiera, an innovative and significantly simplified hierarchical vision transformer that champions efficiency without compromising accuracy. By deploying a potent visual pretext task, MAE, we're able to eliminate the bells-and-whistles from a state-of-the-art multi-stage vision transformer. The result? A lean, mean machine learning model that not only outperforms its predecessors in terms of accuracy but also achieves superior speed, both during inference and training. Tested across a diverse array of image and video recognition tasks, Hiera stands as a beacon of progress in the field of computer vision.

Recognize Anything: A Strong Image Tagging Model
Get ready for a breakthrough in the realm of AI: introducing the Recognize Anything Model (RAM), a powerful new model that is set to revolutionize image tagging. RAM, a titan in the world of large computer vision models, astoundingly exhibits the zero-shot ability to recognize any common category with an impressive level of accuracy. Shattering traditional approaches, RAM employs a unique paradigm for image tagging, utilizing large-scale image-text pairs for training instead of relying on tedious manual annotations.
RAM's development comprises a strategic, four-step process. Initially, annotation-free image tags are obtained on a large scale via an automated text semantic parsing. This is followed by training a preliminary model for automatic annotation, fusing caption and tagging tasks under the supervision of original texts and parsed tags. Then, RAM utilizes a data engine to generate extra annotations and eliminate incorrect ones, refining the input. Finally, the model is meticulously retrained with the cleaned data and fine-tuned using a smaller, higher-quality dataset. Extensive evaluations of RAM have revealed stunning results: it outshines its counterparts like CLIP and BLIP in zero-shot performance, even surpassing fully supervised models, exhibiting a competitive edge akin to Google's tagging API!
