: The method identifies "large residual error points"—areas where the model's current predictions deviate most from the physical laws it is trying to learn. It then adds more training points in those specific regions to refine the model's accuracy. Comparison to Other Methods :

: While adaptive sampling approaches often rank and select points based on residual errors, RAR specifically chooses the "top k" largest residual points without necessarily differentiating between them further. 13988 rar

: Traditional RAR does not differentiate between points if they all have "large" residuals, which can lead to less optimal point selection compared to more modern active-learning-based ranking methods. arXiv:2112.13988v1 [math.NA] 28 Dec 2021 : Traditional RAR does not differentiate between points

: It is generally more memory-efficient than strategies that constantly add new points to the dataset. Weaknesses : : It significantly improves the speed at which

Residual-based Adaptive Refinement is a strategy used to improve the accuracy and efficiency of by intelligently selecting training data points.

: It significantly improves the speed at which a model converges to a solution.
