# MODEL CARD:

## Model Details

• SuperAnimal-Quadruped model developed by the [M.W.Mathis Lab](http://www.mackenziemathislab.org/) in 2023, trained to predict quadruped pose from images. 
Please see [Shaokai Ye et al. 2023](https://arxiv.org/abs/2203.07436) for details.

• The model is an HRNet-w32 trained on our Quadruped-80K dataset.

• It was trained within the DeepLabCut framework. Full training details can be found in Ye et al. 2023.
You can use this model simply with our light-weight loading package called [DLCLibrary](https://github.com/DeepLabCut/DLClibrary). 
Here is an example useage:

```python
from pathlib import Path
from dlclibrary import download_huggingface_model

# Creates a folder and downloads the model to it
model_dir = Path("./superanimal_quadruped_model_pytorch")
model_dir.mkdir()
download_huggingface_model("superanimal_quadruped_pytorch", model_dir)
```

## Intended Use
• Intended to be used for pose estimation of quadruped images taken from side-view. The model serves a better starting
point than ImageNet weights in downstream datasets such as AP-10K.

• Intended for academic and research professionals working in fields related to animal behavior, such as neuroscience
and ecology.

• Not suitable as a zeros-shot model for applications that require high keypiont precision, but can be fine-tuned with
minimal data to reach human-level accuracy. Also not suitable for videos that look dramatically different from those
we show in the paper.

## Factors

• Based on the known robustness issues of neural networks, the relevant factors include the lighting, contrast and
resolution of the video frames. The present of objects might also cause false detections and erroneous keypoints.
When two or more animals are extremely close, it could cause the top-down detectors to only detect only one animal,
if used without further fine-tuning or with a method such as BUCTD (Zhou et al. 2023 ICCV).

## Metrics
• Mean Average Precision (mAP)

## Evaluation Data
• In the paper we benchmark on AP-10K, AnimalPose, Horse-10, and iRodent using a leave-one-out strategy. Here,
we provide the model that has been trained on all datasets (see below), therefore it should be considered “fine-tuned"
on all animal training data listed below. This model is meant for production and evaluation in downstream scientific
applications.

## Training Data:

It consists of being trained together on the following datasets:

- **AwA-Pose** Quadruped dataset, see full details at (1).
- **AnimalPose** See full details at (2).
- **AcinoSet** See full details at (3).
- **Horse-30** Horse-30 dataset, benchmark task is called Horse-10; See full details at (4).
- **StanfordDogs** See full details at (5, 6).
- **AP-10K** See full details at (7).
- **iRodent** We utilized the iNaturalist API functions for scraping observations
with the taxon ID of Suborder Myomorpha (8). The functions allowed us to filter the large amount of observations down to the
ones with photos under the CC BY-NC creative license. The most common types of rodents from the collected observations are
Muskrat (Ondatra zibethicus), Brown Rat (Rattus norvegicus), House Mouse (Mus musculus), Black Rat (Rattus rattus), Hispid
Cotton Rat (Sigmodon hispidus), Meadow Vole (Microtus pennsylvanicus), Bank Vole (Clethrionomys glareolus), Deer Mouse
(Peromyscus maniculatus), White-footed Mouse (Peromyscus leucopus), Striped Field Mouse (Apodemus agrarius). We then
generated segmentation masks over target animals in the data by processing the media through an algorithm we designed that
uses a Mask Region Based Convolutional Neural Networks(Mask R-CNN) (9) model with a ResNet-50-FPN backbone (10),
pretrained on the COCO datasets (11). The processed 443 images were then manually labeled with both pose annotations and
segmentation masks. iRodent data is banked at https://zenodo.org/record/8250392.
**APT-36K** See full details at (12).

</p>

Please note that each dataset was labeled by separate labs \& separate individuals, therefore while we map names
to a unified pose vocabulary (found here: https://github.com/AdaptiveMotorControlLab/modelzoo-figures), there will be annotator bias in keypoint placement (See the Supplementary Note on annotator bias). 
You will also note the dataset is highly diverse across species, but collectively has more representation of domesticated animals like dogs, cats, horses, and cattle. 
We recommend if performance is not as good as you need it to be, first try video adaptation (see Ye et al. 2023), 
or fine-tune these weights with your own labeling.


## Ethical Considerations

• No experimental data was collected for this model; all datasets used are cited.

## Caveats and Recommendations

• The model may have reduced accuracy in scenarios with extremely varied lighting conditions or atypical animal
characteristics not well-represented in the training data.

• Please note that each dataest was labeled by separate labs & separate individuals, therefore while we map names to a
