Figure 6

Comparison of actual y versus estimated y plots when using the original circuit (L = 2) or the MERA circuit as the variational circuit. The left column shows the plots for the original circuit (L = 2), and the right column shows those for the MERA circuit. The top row shows the estimation of y trained on all the data, and the bottom row shows the results predicted through the tenfold cross-validation. The expected predicted value obtained from the quantum circuit was calculated directly from the state vector held by the simulator.
