  • 网络扩展资料

    监督分类是机器学习中的一种方法,它是将样本数据集划分为若干个类别的过程。该过程是在已有标注好的数据的基础上进行的,其中“标注”指的是每个样本所属的类别已经被人工标记出来了。

    用法

    在监督分类中,算法会使用已有的标注数据集来学习每个类别的特征,然后将这些特征应用于新的未标注数据集,以对其进行分类。例如,一个监督分类算法可以使用已知的标签(如“狗”和“猫”)来训练模型,然后将此模型应用于新的图像,以确定图像中的动物是狗还是猫。

    例句

    • 英文例句:In supervised classification, a computer program is trained on a set of labeled examples.
    • 中文例句:在监督分类中,计算机程序通过一组已标记的示例进行训练。

    解释

    监督分类需要一个标注好的数据集来进行训练,这个数据集必须包括样本的特征和它们所属的类别。监督分类算法会分析这个数据集并学习每个类别的特征,以便在未来对新的数据进行分类。该算法将数据集分为训练集和测试集。训练集用于训练模型,而测试集用于评估模型的精度和性能。监督分类算法可以应用于各种各样的问题,例如垃圾邮件过滤、情感分析、图像分类等。
