EikoNet: Solving the Eikonal equation with Deep Neural Networks

Smith, Jonathan D., Azizzadenesheli, Kamyar, Ross, Zachary E.

Understand

The recent deep learning revolution has created an enormous opportunity for accelerating compute capabilities in the context of physics-based simulations.

  • Here, we propose EikoNet, a deep learning approach to solving the Eikonal equation, which characterizes the first-arrival-time field in heterogeneous 3D velocity structures.
  • Our grid-free approach allows for rapid determination of the travel time between any two points within a continuous 3D domain.
  • These travel time solutions are allowed to violate the differential equation - which casts the problem as one of optimization - with the goal of finding network parameters that minimize the degree to which the equation is violated.
