Covariance-based weighting for optimal combination of network predictions

This paper introduces a method for calculating the covariance between different neural network solutions. It is based on a generalisation of the delta method for calculating the network Hessian and generates what we call the 'cross-covariance' matrix (its inverse is the 'cross-Hessian...
