“bias-variance decomposition”的概念、定义、翻译、参考文献-科学参考

单词	bias-variance decomposition
释义	bias-variance decomposition Encyclopedia 理学学习理论释 bias-variance decomposition偏差-方差分解解释算法泛化性能的一种重要工具。它试图对学习算法的期望泛化误差错误率拆解成偏差、方差及噪声三项。人们需要对模型的性能进行评估来比较和选择模型。一般可以通过将数据集划分成训练集（training set）和测试集（testing set），在训练集上进行训练，然后以测试集上的测试误差（testing error）来做为泛化误差的近似。
