Training Restricted Boltzmann Machines for General Spin Quantum Magnets — •Abhiroop Lahiri and Michele Casula — IMPMC, Sorbonne Université, Paris, France

Neural Network Quantum states (NQS) have gained popularity in recent times for their ability to study quantum many-body systems. Restricted Boltzmann Machines (RBMs) have been quite successful in providing an accurate representation of the ground states of spin-1/2 quantum systems both in one and two dimensions. Based on recent studies of the spin-1 representation of RBMs using one-hot encoding and a quadratic energy function, we aim to test these ansatze for general spin models in various configurations. We train the network parameters and investigate their behaviour to resolve the ground state of these systems.
