幂后验的预测性能
Predictive performance of power posteriors
AI总结:
本文研究幂后验中调温似然对后验预测的影响,证明温度仅在小样本下影响预测性能,中到大样本时调温不改变后验预测。
摘要:
我们分析了在后验预测生成中使用调温似然的影响。尽管温度选择在小样本中会影响预测性能,但我们严格证明,在中等到大样本中,调温不会影响后验预测。
英文摘要:
We analyse the impact of using tempered likelihoods in the production of posterior predictions. While the choice of temperature has an impact on predictive performance in small samples, we formally show that in moderate-to-large samples, tempering does not impact posterior predictions.
