研究人员开发了一种名为Richardson-SGD的新颖方法，用于解决随机梯度下降（SGD）在处理不完整数据时出现的梯度偏差问题。该技术通过故意向数据引入额外的缺失值，然后结合不同缺失级别下的梯度来抵消偏差。这种方法不依赖于特定模型，计算效率高，并且在优化和估计方面对各种模型都显示出实证改进，即使与MICE等现有插补方法结合使用也是如此。 AI
影响 引入了一种新颖的技术，以提高在不完整数据集上训练的机器学习模型的准确性。

Stochastic gradient methods are central to modern large-scale learning, but their use with incomplete covariates remains delicate since imputation schemes generally introduce systematic gradient biases, as shown for linear models. In this work, we prove that all parametric models…
