Ensemble and Mixture-of-Experts DeepONets For Operator Learning

no code implementations20 May 2024 Ramansh Sharma, Varun Shankar

We also present a spatial mixture-of-experts (MoE) DeepONet trunk network architecture that utilizes a partition-of-unity (PoU) approximation to promote spatial locality and model sparsity in the operator learning problem.

Accelerated Training of Physics-Informed Neural Networks (PINNs) using Meshless Discretizations

1 code implementation19 May 2022 Ramansh Sharma, Varun Shankar

Finally, we also demonstrate that similar results can be obtained for the PINN solution to the heat equation (a space-time problem) by discretizing the spatial derivatives using RBF-FD and using automatic differentiation for the temporal derivative.
