XPose: Explainable Human Pose Estimation Framework with Group Shapley Value
Khái niệm cốt lõi
Integrating XAI principles into pose estimation enhances model transparency and interpretability through Group Shapley Value.
Tóm tắt
This paper introduces XPose, a framework that integrates Explainable AI (XAI) principles into pose estimation. It proposes a novel concept called Group Shapley Value (GSV) to assess the contribution of each keypoint to final predictions. The paper also introduces a data augmentation technique known as Group-based Keypoint Removal (GKR) to enhance the model's ability to infer invisible keypoints. Experimental results across three typical methods demonstrate the effectiveness of the proposed approach.

How can XAI principles be applied to other computer vision tasks beyond pose estimation
XAI principles can be applied to other computer vision tasks beyond pose estimation by enhancing the transparency and interpretability of model decisions. For instance, in object detection tasks, XAI techniques can help explain why certain objects are detected or missed in an image. By understanding the rationale behind model predictions, researchers and practitioners can gain insights into how the model processes visual information and make more informed decisions about model improvements.
What are potential drawbacks or limitations of using Group Shapley Value in pose estimation models
One potential drawback of using Group Shapley Value in pose estimation models is the computational complexity involved in clustering keypoints and calculating shapley values within and across groups. As the number of keypoints increases, the computation required for fine-grained shapley value calculations may become prohibitive. Additionally, defining meaningful keypoint clusters based on interdependencies may introduce biases or inaccuracies if not done carefully. Moreover, interpreting group-level shapley values accurately requires a deep understanding of keypoint relationships, which could be challenging to capture comprehensively.
How might advancements in XAI impact the future development of deep learning technologies
Advancements in XAI have the potential to significantly impact the future development of deep learning technologies by promoting trustworthiness, accountability, and fairness in AI systems. With improved explainability through methods like Group Shapley Value introduced in XPose framework for pose estimation models, developers can better understand how models arrive at their decisions. This increased transparency can lead to more robust models with reduced bias and improved performance across various applications such as healthcare diagnostics, autonomous vehicles, natural language processing systems among others.
