Forward and inverse problems for Eikonal equation based on DeepONet

Understand

Seismic forward and inverse problems are significant research areas in geophysics.

• However, the time burden of traditional numerical methods hinders their applications in scenarios that require fast predictions.
• Machine learning-based methods also have limitations as retraining is required for every change in initial conditions.
• In this letter, we adopt deep operator network (DeepONet) to solve forward and inverse problems based on the Eikonal equation, respectively.
