摘要:

我们研究并扩展了Vovk,Gammerman和Shafer(2005)的共形预测方法来构建非参数预测区域。这些区域保证了无分布、有限的样本覆盖率,而没有对分布或带宽的任何假设。明确的收敛速度的损失函数建立在标准的正则性条件下的区域。简化实现的近似和数据驱动的带宽选择方法也进行了讨论。我们的方法的理论特性,通过模拟证明。

英文摘要:

We investigate and extend the conformal prediction method due to Vovk,Gammerman and Shafer (2005) to construct nonparametric prediction regions. These regions have guaranteed distribution free, finite sample coverage, without any assumptions on the distribution or the bandwidth. Explicit convergence rates of the loss function are established for such regions under standard regularity conditions. Approximations for simplifying implementation and data driven bandwidth selection methods are also discussed. The theoretical properties of our method are demonstrated through simulations.
