that it didn't have this ground truth vector x star so it's exactly the same loss function but the tensor and the matrix is created without this ground true planted in but that's you know that's that's a complication of the model that can be worked out and you know this theory from this paper can be generalized and this is what we did i will not be going into details of the of the derivation that would be very lengthy but if you are interested in the details actually just um two months ago there has been a wonderful lecture by
