YOLOS looks at patches of an image to to form "patch tokens", which are used in place of the traditional wordpiece tokens in NLP. There are 100 detection tokens on the right are learnable embeddings and feed into potential detections.

Compared to other CNN-based YOLO models, YOLOS benefits from the rising tides of transformers in computer vision, as well as inferring without the need for NMS, a tedious post-processing step that makes the deployment of other YOLO models difficult and slow.

YOLOS - You Only Look At One Sequence

Unlike previous CNN based YOLO models, the YOLOS backbone is a Transformer block, much like the first vision transformer for classification.

Train YOLOS Transformer On a Custom Dataset

In this post, we showcase how to create a YOLOS object detection labeling, training, and deployment pipeline.

YOLOS Annotation Format

YOLOS

uses the

COCO JSON

annotation format. If your annotation is in a different format, you can use Roboflow's annotation conversion tools to get your data into the right format.
