A thermodynamic computing system for sampling high-dimensional probability distributions

The thermodynamic computing platform samples multivariate distributions (e.g., multivariate Gaussian distributions) using a network of coupled analog unit cells controlled by a digital processor. The analog unit cells are capacitively, resistively, and / or inductively coupled to each other. Each analog unit cell contains an adjustable resistor, capacitor, inductor, current source, and / or voltage source. The digital processor sets initial values ​​for these components. These values, or input parameters, represent the multivariate distribution. The network of coupled analog unit cells is then evolved through a series of time steps until thermal equilibrium is reached. As the network evolves, the digital processor samples voltages at nodes in the network at each time step. These voltages represent samples of the multivariate distribution.
