: It significantly improves the speed at which a model converges to a solution.
: 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 13988 rar
: 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. : It significantly improves the speed at which
: Other sophisticated adaptive strategies can become computationally expensive as the number of training points accumulates over time. RAR is often viewed as a more balanced fit because it can refine the model without letting the training set grow uncontrollably. Strengths : It then adds more training points in those
: 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 :
: It is generally more memory-efficient than strategies that constantly add new points to the dataset. Weaknesses :
