Before revision:  The main idea of NOMU is to design a network architecture consisting of two connected sub-networks , one for the model prediction and one for the model uncertainty, and to train it using a carefully designed loss function.
After revision:  The main idea of NOMU is to design a network architecture consisting of two connected sub-NNs , one for the model prediction and one for the model uncertainty, and to train it using a carefully designed loss function.
