This work introduces a technique to lower the overhead in measurement statistics to achieve accurate estimations of observables relevant in quantum simulations. The approach consists of integrating artificial neural networks with the measurement apparatus of a quantum simulator. By training the neural networks with unsupervised learning of single-qubit measurements, the authors demonstrate a significant decrease in the number of measurements required to reach precise estimates in quantum chemistry applications
