UnverifiedTop-p（核采样）通过限定候选token的累积概率范围来控制输出多样性，与Temperature配合使用可实现更精细的输出调节78% similarVerifiedTemperature controls the flatness of the sampling distribution; a higher value tends toward selecting lower-probability words, while Top-p dynamically narrows the candidate vocabulary set through a cumulative probability threshold.78% similarUnverifiedCoze's Top-P nucleus sampling mechanism starts from the highest-probability words and accumulates probabilities until the cumulative probability reaches the set P value, sampling only from those words.76% similarUnverifiedIncorporating retrieval quality metrics (such as recall@K) and latency metrics (P95, P99) into the same evaluation framework can avoid suboptimal decisions caused by single-dimension optimization.72% similarUnverifiedRAG调优中Top K（返回最相关的K个片段）和相似度阈值是最常需要调整的两个参数71% similar
