Keypoint-MoSeq: parsing behavior by linking point tracking to pose dynamics

Mackenzie Mathis, Alexander Mathis, Shaokai Ye

Keypoint tracking algorithms can flexibly quantify animal movement from videos obtained in a wide variety of settings. However, it remains unclear how to parse continuous keypoint data into discrete actions. This challenge is particularly acute because key ...

SuperAnimal pretrained pose estimation models for behavioral analysis

Tian Qiu, Maxime Michel André Vidal, Mackenzie Mathis, Alexander Mathis, Shaokai Ye, Jessy Lauer, Steffen Schneider

Quantification of behavior is critical in diverse applications from neuroscience, veterinary medicine to animal conservation. A common key step for behavioral analysis is first extracting relevant keypoints on animals, known as pose estimation. However, re ...

AmadeusGPT: a natural language interface for interactive animal behavioral analysis

Mackenzie Mathis, Alexander Mathis, Shaokai Ye, Jessy Lauer

The process of quantifying and analyzing animal behavior involves translating the naturally occurring descriptive language of their actions into machine-readable code. Yet, codifying behavior analysis is often challenging without deep understanding of anim ...

Multi-animal pose estimation, identification and tracking with DeepLabCut

Tanmay Nath, Mackenzie Mathis, Alexander Mathis, Shaokai Ye, Jessy Lauer, Steffen Schneider

Estimating the pose of multiple animals is a challenging computer vision problem: frequent interactions cause occlusions and complicate the association of detected keypoints to the correct individuals, as well as having highly similar looking animals that ...

Non-Structured DNN Weight Pruning--Is It Beneficial in Any Platform?

Shaokai Ye

Large deep neural network (DNN) models pose the key challenge to energy efficiency due to the significantly higher energy consumption of off-chip DRAM accesses than arithmetic or SRAM operations. It motivates the intensive research on model compression wit ...

QAIR: Practical Query-efficient Black-Box Attacks for Image Retrieval

Hang Su, Jinfeng Li, Shaokai Ye, Yuan He

We study the query-based attack against image retrieval to evaluate its robustness against adversarial examples under the black-box setting, where the adversary only has query access to the top-1 ranked unlabeled images from the database. Compared with que ...

Adversarial Laser Beam: Effective Physical-World Attack to DNNs in a Blink

Shaokai Ye, Yuan He

Though it is well known that the performance of deep neural networks (DNNs) degrades under certain light conditions, there exists no study on the threats of light beams emitted from some physical source as adversarial attacker on DNNs in a real-world scena ...
