Why have to set weight?

Hi Gary,
Thank you for sharing your code.
I was wondering at input transform and feature transform, why do we have to set it:
x = Dense(9, weights=[np.zeros([256, 9]), np.array([1, 0, 0, 0, 1, 0, 0, 0, 1]).astype(np.float32)])(x) input_T = Reshape((3, 3))(x)
f = Dense(64 * 64, weights=[np.zeros([256, 64 * 64]), np.eye(64).flatten().astype(np.float32)])(f) feature_T = Reshape((64, 64))(f)
Could you tell me why?
Thank you very much.
Minh

I think It's because it's mentioned in the paper that you should initialize with the identity matrix
