Unverified在行数波动显著的场景下，平均聚合通常是更稳健的起点，但如果分类信号与特定元素存在性强相关则最大值聚合可能更佳72% similarUnverifiedThe optimal regularization strength needs to be selected through cross-validation; if it is too large it leads to underfitting, and if it is too small the regularization effect is negligible.70% similarUnverifiedAs large model reasoning capabilities strengthen, the tokens consumed per single call rise significantly, creating a paradox of 'stronger model' versus 'faster limit reached' under fixed usage limits.70% similarUnverified在实践中优先明确约束与停止条件这两个负向维度，比精心描述正向目标更能快速压制冗余输出69% similarUnverified扩散模型步数越多理论上结果越精细，但耗时也成比例增长，20步是速度与质量的经典平衡点67% similar
