New framework AD-RaNN optimizes randomized neural networks for PDEs

Researchers have introduced Adaptive-Distribution Randomized Neural Networks (AD-RaNN), a new framework designed to improve the performance of randomized neural networks in solving partial differential equations (PDEs). This method addresses the sensitivity of existing models to the sampling distribution of hidden-layer parameters by optimizing a low-dimensional vector that defines this distribution. AD-RaNN employs a two-stage training process, incorporating adaptive mechanisms like PDE-Driven Adaptive Distribution (PDAD) and Data-Driven Adaptive Distribution (DDAD) to enhance accuracy and reduce manual tuning.
