Twin neural network regression
Applied AI Letters, Volume 3, Issue 4, December 2022., 2022 We propose to reformulate a regression problem into predicting differences between target values. This allows for leveraging consistency conditions which can be used as uncertainty estimates and enable the production of an ensemble of predictions while training only a single neural network.
