As an aside, some machine learning techniques use a fourth set of data, called a validation set, which is used during training to avoid overfitting.
另一方面，一些机器学习技术使用第四种数据集，称为验证集[validationset]，它被用来在整个训练期间避免过适合[overfitting]。
That is, some branches of the tree that may lead to the model overfitting are cut off.
这就是说，树的某些导致模型过拟合的分支将被剪掉。
A post pruning procedure is designed to deal with the overfitting problem, and two criteria that are the minimum covering rate and the minimum error rate are defined.
同时，基于最小覆盖率和最小错误率给出了一种克服过学习问题的后处理方法。
This method is robust to Gaussian noise and constellation rotation due to initial phase of signal and avoids overfitting and local minimum in neural networks.
这种方法对高斯噪声和星座图由于信号初始相位而引入的旋转具有良好的稳健性，并避免了神经网络中的过学习和局部极小点等缺陷。
