Training a Custom YOLO Model for Posture Detection
Read Full Article: Training a Custom YOLO Model for Posture Detection
Embarking on a machine learning journey, a newcomer trained a YOLO classification model to detect poor sitting posture, discovering valuable insights and challenges. While pose estimation initially seemed promising, it failed to deliver results, and the YOLO model struggled with partial side views, highlighting the limitations of pre-trained models. The experience underscored that a lower training loss doesn't guarantee a better model, as evidenced by overfitting when validation accuracy remained unchanged. Utilizing the early stopping parameter proved crucial in optimizing training time, and converting the model from .pt to TensorRT significantly improved inference speed, doubling the frame rate from 15 to 30 FPS. Understanding these nuances is essential for efficient and effective model training in machine learning projects.
