An example of use of Variational Methods in Quantum Machine Learning. (arXiv:2208.04316v1 [quant-ph])

This paper introduces a deep learning system based on a quantum neural
network for the binary classification of points of a specific geometric pattern
(Two-Moons Classification problem) on a plane. We believe that the use of
hybrid deep learning systems (classical + quantum) can reasonably bring
benefits, not only in terms of computational acceleration but in understanding
the underlying phenomena and mechanisms; that will lead to the creation of new
forms of machine learning, as well as to a strong …
