I have implemented a hybrid quantum NN on a dataset to perform classification. Now I want to apply quantum PCA to my dataset to find the eigenvalues. After going through a few qiskit tutorials, I found that VQE is used for finding eigenvalues in qiskit. Is there a demo program implementing VQE on a dataset where we can check the steps?
The Qiskit textbook chapter on VQE is specific to molecule ground state, though it has a good introduction on what VQE is and how it works.
