Nonlinear operators with long-distance spatiotemporal dependencies are fundamental in modelling complex systems across sciences; yet, learning these non-local operators remains challenging in machine ...
Many physics problems involve integration in multi-dimensional space whose analytic solution is not available. The integrals can be evaluated using numerical integration methods, but it requires a ...
Using the path-integral formalism, Ryan Parker, Mark Stedman and Luca Capriotti develop an accurate and easy-to-compute semi-analytical approximation for a general class of default intensity models.
