Surrogate model development is a critical step for uncertainty quantification or other sample-intensive tasks for complex computational models. In this work we develop a multi-output surrogate form using a class of neural networks (NNs) that employ shortcut connections, namely Residual NNs (ResNets)...
18 proposed a data-driven approach to quantify the prediction uncertainty of deep neural networks (DNNs), paving the way for a comprehensive treatment of uncertainty in DNN-based diagnostic systems. Saxena et al.19 applied an advanced convolutional neural network model for early detection of DR to...
this uncertainty makes it very virtually impossible to evaluate—analytically or through intuition—the true inference potential from a given set of device characteristics. Our weight programming optimisation approach can thus—given a fairly modest set of conductance-programming, drift and noise characteris...

The adjustment of the weights in the backpropagation learning using interval type-2 fuzzy numbers is the main contribution of the proposed work in this paper for neural networks. This contribution provides to the neural network the robustness to support real data with uncertainty [16–18]. The ...

Agriculture has always been based on mass labor and intensive physical work, with the results heavily dependent on weather and climate conditions [42]. Despite the everlasting uncertainty of crop yields, the increasing demand for food due to rapid population growth, Fig.1, has provided farmers wit...
