Dear all, we hope you have had a great break.
The plans for this week are to discuss and finalize how to implement the VQE method for the eigenvalue problems discussed in the project. We will also discuss how to use gradient descent methods with and without analytical gradients.
The material on gradient descent methods is taken from FYS-STK4155, see
https://github.com/CompPhysics/MachineLearning/blob/master/doc/pub/week39/ipynb/week39.ipynb and the expressions for the analytical gradients are taken from the article of Schuld et al, see
https://journals.aps.org/pra/abstract/10.1103/PhysRevA.99.032331
We will go through these derivations during the lecture on Monday April 17. The lecture notes (they are updated continuously) are at
