As a design problem can be formulated as an inverse problem, i.e., starting from the design requirements the optimal values of the design parameters have to be obtained, the input of the neural network will correspond to the design parameters while the output is the objective function of the...

implementing them to improve the performance and training of this network. In order to support your experiments, we have acquired Google Cloud Platform credits which allow the use of the Google Compute Engine infrastructure. You will need this to run all the tasks of the coursework (which ...
A neural network has a tendency to memorize its training data, especially if it contains more than enough capacity. In this case, the network fails catastrophically when subjected to the test data. This is the classic case that the network fails to generalize (Overfitting / Underfitting). To ...
the parameters of the simple network with one hidden layer, whose computational graph is in :numref:`fig_forward`, are $\mathbf{W}^{(1)}$ and $\mathbf{W}^{(2)}$. The objective of backpropagation is to calculate the gradients $\partial J/\partial \mathbf{W}^{(1)}$ and $\parti...
