You are most likely reporting the validation result.

Could you clarify which result you are referring to? Are you trying to reproduce the frontal results? The code is designed to reproduces 13.5 degrees ( all 360 degree )

Hmm .. I have reproduced the authors code many times and I can confirm that I can reproduce 13.5.
I recommend first downloading the weights provided by the authors and confirm if you can reproduce 13.5. If not, then it indicates some data files might be missing.

[Hopedreams]

Thank you very much.Inspired by you,I reconfirmed and the result is 13.5.

Why are pitch and yaw defined in this way?

[erkil1452]

The tanh should not be interpreted geometrically. It is a common nonlinearity used in machine learning and we use it to squeeze the output to the range (-1,1). This is then easy to rescale to the range required for yaw (-pi, pi) and pitch (-pi/2, pi/2) angles as seen above.

[Hopedreams]

Is the output of the model a three-dimensional vector?

The output is yaw and pitch in polar coordinates which can be converted into 3D direction using

x = sin(yaw) * cos(pitch)
y = sin(pitch)
z = cos(yaw) * cos(pitch)

[Hopedreams]

Does this 3D direction refer to the coordinates (x, y, z) of the vector in the Cartesian coordinate system?

[erkil1452]

Yes, it is a 3D direction in the Cartesian coordinate system of the camera.

[Hopedreams]

What do these three output values represent respectively? Thank you very much

The gaze vector components (x, y and z).
