摘要

最近的研究揭示了边际保形预测在药物发现的校准虚拟筛选中的一个重要局限性。尽管该方法通常实现高覆盖率，但在不平衡数据集中，它未能充分代表少数类，这可能导致对不常见但关键药物靶点的预测不足。为了解决这个问题，研究人员提出了一种类条件修正，改善了这些少数类的覆盖率，而不会显著增加预测集的大小，从而提高了药物发现应用中的预测可靠性。

Recent research has highlighted a significant limitation in the application of marginal conformal prediction within calibrated virtual screening for drug discovery. While this method generally achieves high coverage rates, it has been found to under-represent minority classes in imbalanced datasets, which can lead to inadequate predictions for less common but critical drug targets. To address this issue, the researchers proposed a class-conditional fix that improves coverage for these minority classes without substantially increasing the size of the prediction set, thereby enhancing the reliability of predictions in drug discovery applications.

  2. 提出的类条件修正在不显著扩展预测集的情况下改善了少数类的覆盖率。

    A proposed class-conditional fix improves minority class coverage without significantly expanding prediction sets.

  3. 这项研究强调了在药物发现的预测建模中解决类不平衡的重要性。
