基于分位数回归的分布强化学习(Distributional Reinforcemet Learning with Quantile Regression) 范围很大时,能够进行更精确的预测 避免了C51中的投影操作 这种再参数化允许我们使用分位数回归来最小化Wasserstein损失,而不受有偏梯度的影响。 3.QuantileRegression(分位数回归) 接下来就是重头戏——分位数回归,它是分布...
In this paper, we discuss a family of robust, high-dimensional regression models for quantile and composite quantile regression, both with and without an adaptive lasso penalty for variable selection. We reformulate these quantile regression problems and obtain estimators by applying the alternating ...

The spatially-distributed model simulations are then analysed with the quantile regression method to reveal the spatial and temporal patterns of regional water resources. The results show that this approach excels in presenting distributed, spatially focused trend information for extremely dry and wet ...

Regression results indicate that females excel at writing and grammar at later grades whereas males outperform females in numeracy in all grades, whether at the mean or along the distribution of the test score. Our results also reveal a widening gender test score gap in writing and numeracy as ...

Notably, the spillover effects under extreme lower and upper tail conditions are not consistent, as the occurrence of extreme values does not coincide, suggesting an asymmetry in the spillover effects at these quantiles.
