VerifiedElastic Weight Consolidation (EWC) estimates the importance of parameters to old tasks via the Fisher information matrix and applies stronger regularization penalties to important parameters to mitigate catastrophic forgetting.69% similarUnverifiedUsing EWC in a task-complementary scenario to lock parameters near the old optimal position hinders the model from fully absorbing financial-domain-specific patterns, thereby lowering overall performance.67% similarUnverifiedmini-KFAC is a further simplification of full KFAC that controls memory and computational overhead by reducing the number of samples used for statistical estimation per layer, striking a balance between accuracy and efficiency.67% similarUnverifiedStandard EWC typically uses a diagonal Fisher information matrix to approximate parameter importance, which has low computational cost but assumes parameter independence, ignores inter-parameter correlations, and is too coarse an approximation for highly coupled neural networks.66% similarUnverified受限的输出空间意味着更少的出错可能以及更容易被程序化验证的结果，约束是LLM可靠性的本质来源65% similar
