Dropout Feature Ranking的核心思想是将特征的重要性融入到模型的学习过程中,使得特征选择和模型优化同步进行,不仅效率高还能使两者优化目标保持一致,特征选择更加有效。 具体做法是给每个特征的embedding结果加一个扰动变量,使其有一定概率出现在神经网络中,同时加入正则,使得低重要度的特征出现在神经网络中的概率低。最后...

Consequently, the POS and Kendall’s rank correlation score were significantly increased (POS from 0.61 to 0.94; Kendall’s rank correlation from 0.44 to 0.77). In summary, these results suggested that imputing dropout events using DrImpute also improved the performance of pseudotime inference using...
