According to the paper, HCP-PINN performs similarly to an equivalent ordinary PINN in the early stage of training, with the two loss curves almost overlapping; when the loss of the ordinary PINN enters a plateau, the loss of HCP-PINN continues to decrease.

UnverifiedThe fundamental idea of PINNs is to incorporate the residual of partial differential equations (PDEs) as an additional loss term in the training objective, so that the network satisfies the equation constraints while fitting observational data.65% similarUnverifiedThe long-horizon credit assignment problem is typically mitigated through discounted returns (discount factor γ), but values of γ closer to 1 lead to increased variance in gradient estimation and training instability.63% similarUnverifiedA cosine annealing learning rate schedule may help the model break through loss plateaus and avoid getting stuck in local optima.62% similarUnverifiedExperimental conclusion two: some self-distillation methods give attractive scores at the end of training, but during training they exhibit severe performance fluctuations or even collapse followed by recovery, and these problems cannot be found by looking only at the final metric.62% similarUnverifiedKey theoretical challenges facing PINNs include optimization difficulties caused by the non-convexity of the loss function, spectral bias making high-frequency components difficult to learn, and the lack of theoretical guidance for multi-term loss function weighting strategies.61% similar
