In this Letter, we teach a neural network the solution of the Schrsdinger equation for some model potential energy functions. The network can then predict eigenvalues of other test cases with an error of a few percent.

β¦ Synopsis
The application of artificial neural networks to the identification of harmonic loads has been demonstrated before with great success. In this paper, practical aspects of such an application are discussed. While it is known that the selection of features, the choice of the architecture (number of hidden layers) and topology (number of hidden units in each hidden layer) of the neural network are heuristic decisions involving engineering judgement, this paper shows one such way and claims success in that implementation. A supervised learning procedure is adopted and the familiar back-propagation technique is used in training the network. The need for preprocessing raw data from a power system before being input to a neural network is examined. Finally, the performance of the neural network is evaluated with the aid of a benchmark case.

Two problems occur in the design of feedforward neural networks: the choice of the optimal architecture and the initialization. Generally, input and output data of a system (or a function) are measured and recorded. Then, experimenters wish to design a neural network to map exactly these output valu
