In the GCMDP we use linear geometry structure as constraint, dynamically optimize in the picking process, and apply multi-step prediction to the first break position and multi-attribute constraint...

... In this research, we combine data-driven and physics-driven strategies to train a physics-informed neural network for the simulation of electromagnetic wave propagation. By leveraging the constraints from the partial differential equation, the pre-trained network is able to efficiently predict...

... (kilometer scale). The second challenge concerns the density of borehole dips. Highly dense dip data lead to a larger number of equations in the linear system that we must solve when computing the implicit model, introducing potentially conflicting constraints into the system. To handle these challenges, we...
