I have data that has equal variance along each of the target dimensions, but if i analyze the results of training i notice that that my trained model does not have the same error variances along each of the dimensions, which means some dimensions are more erroneous than others.



Does this say anything about the model missing some sort of regularization, or is this not something I should be fretting over? Is there a way I can regularize to make sure the errors along different dimensions have the same variance?
