coco joint_weights

[smidm]

Most datasets use equal weights for all joints in training loss. Only COCO and few related datasets use following:

joint_weights=[
  1., 1., 1., 1., 1., 1., 1.,  # 'nose', 'left_eye', 'right_eye', 'left_ear', 'right_ear', 'left_shoulder', 'right_shoulder',   
  1.2, 1.2,  # 'left_elbow', 'right_elbow',   
  1.5, 1.5,  # 'left_wrist', 'right_wrist', 
  1., 1.,    # 'left_hip', 'right_hip',
  1.2, 1.2,  # 'left_knee', 'right_knee', 
  1.5, 1.5,  # 'left_ankle', 'right_ankle',
]

Is there a source or a reason for these particular weights?

We have transfered these weights from HRNet, but they are rarely used.
