Abstract Data scarcity is a major challenge when training deep learning (DL) models. DL demands large amount of data to achieve exceptional performance. Unfortunately, many applications have small or inadequate train frameworks. Usually, manual labeling needed provide labeled data, which typically involves human annotators with vast background knowledge. This annotation process costly, time-consuming, and error-prone. every framework fed by significant automatically learn representations. Ultimately, larger would generate better model its performance also application dependent. issue the main barrier for dismissing use DL.

Our recent intensive study has found that physics-informed neural networks (PINN) tend to be local approximators after training. This observation leads this novel radial basis network (PIRBN), which can maintain the property throughout entire training process. Compared deep networks, a PIRBN comprises of only one hidden layer and "activation" function. Under appropriate conditions, we demonstrated PIRBNs using gradient descendent methods converge Gaussian processes. Besides, studied dynamics via tangent kernel (NTK) theory. In addition, comprehensive investigations regarding initialisation strategies were conducted. Based on numerical examples, been more effective efficient than PINN in solving PDEs with high-frequency features ill-posed computational domains. Moreover, existing techniques, such as adaptive learning, decomposition different types loss functions, are applicable PIRBN.
