-Supervised learning of image classifiers distills human knowledge into a parametric model *f* through pairs of images and corresponding labels (*X*,*Y*). We argue that this simple and widely used representation of human knowledge neglects rich auxiliary information from the annotation procedure, such as the time-series of mouse traces and clicks.

-
-Our insight is that such **annotation byproducts** *Z* provide approximate human attention that weakly guides the model to focus on the foreground cues, reducing spurious correlations and discouraging shortcut learning. 
-
-We have created **ImageNet-AB** and **COCO-AB** to verify this.
-
-They are ImageNet and COCO training sets enriched with sample-wise annotation byproducts, collected by replicating the respective original annotation tasks. 
-
-We refer to the new paradigm of training models with annotation byproducts as **learning using annotation byproducts (LUAB)**.

-
-We show that a simple multitask loss for regressing *Z* together with *Y* already improves the generalisability and robustness of the learned models. Compared to the original supervised learning, LUAB does not require extra annotation costs.
+## General Information
+
+**Title**: COCO-AB
+
+**Description**: 
+The COCO-AB dataset is an extension of the COCO 2014 training set, enriched with additional annotation byproducts (AB). 
+The data includes 82,765 reannotated images from the original COCO 2014 training set. 
+It has relevance in computer vision, specifically in object detection and location. 
+The aim of the dataset is to provide a richer understanding of the images (without extra costs) by recording additional actions and interactions from the annotation process.

+
+
+## Collection Process
+
+**Collection Details**:
+The additional annotations for the COCO-AB dataset were collected using Amazon Mechanical Turk (MTurk) workers from the US region, due to the task being described in English. 
+The task was designed as a human intelligence task (HIT), and the qualification approval rate was set at 90% to ensure the task's quality.
+Each HIT contained 20 pages of annotation tasks, each page having a single candidate image to be tagged.
+We follow the original annotation interface of COCO as much as possible.
+See [GitHub repository](https://github.com/naver-ai/coco-annotation-tool) and [Paper](https://arxiv.org/abs/2303.17595) for further information.
+
+
+A total of 4140 HITs were completed, with 365 HITs being rejected based on criteria such as recall rate, accuracy of icon location, task completion rate, and verification with database and secret hash code.
+
+**Annotator Compensation**:
+Annotators were paid 2.0 USD per HIT. 
+The median time taken to complete each HIT was 12.1 minutes, yielding an approximate hourly wage of 9.92 USD. 
+This wage is above the US federal minimum hourly wage. 
+A total of 8,280 USD was paid to the MTurk annotators, with an additional 20% fee paid to Amazon.
+
+**Annotation Rejection**: 
+We rejected a HIT under the following circumstances.
+
+- The recall rate was lower than 0.333.
+- The accuracy of icon location is lower than 0.75.
+- The annotator did not complete at least 16 out of the 20 pages of tasks.
+- The annotation was not found in our database, and the secret hash code for confirming their completion was incorrect.
+- In total, 365 out of 4,140 completed HITs (8.8%) were rejected.
+
+
+**Collection Time**:
+The entire annotation collection process took place between January 9, 2022, and January 12, 2022

-### Dataloader for ImageNet-AB and COCO-AB
+## Usage
 
-We provide example dataloaders for the annotation byproducts.
+One could use the annotation byproducts to improve the model generalisability and robustness.
+This is appealing, as the annotation byproducts do not incur extra annotation costs for the annotators.
+For more information, refer to our [ICCV'23 Paper](https://arxiv.org/abs/2303.17595).

+## Dataset Statistics
 
+Annotators have reannotated 82,765 (99.98%) of 82,783 training images from the COCO 2014 training set.
+For those images, we have recorded the annotation byproducts. 
+We found that each HIT recalls 61.9% of the list of classes per image, with the standard deviation ±0.118%p.
+The average localisation accuracy for icon placement is 92.3% where the standard deviation is ±0.057%p.

+## Ethics and Legalities
+The crowdsourced annotators were fairly compensated for their time at a rate well above the U.S. federal minimum wage. 
+In terms of data privacy, the dataset maintains the same ethical standards as the original COCO dataset.
+Worker identifiers were anonymized using a non-reversible hashing function, ensuring privacy.
 
-### License
+Our data collection has obtained IRB approval from an author’s institute. 
+For the future collection of annotation byproducts, we note that there exist potential risks that annotation byproducts may contain annotators’ privacy. 
+Data collectors may even attempt to leverage more private information as byproducts. 
+We urge data collectors not to collect or exploit private information from annotators. 
+Whenever appropriate, one must ask for the annotators’ consent.
