分类(classification) 有监督学习的两大应用之一,产生离散的结果。 例如向模型输入人的各种数据的训练样本,产生“输入一个人的数据,判断是否患有癌症”的结果,结果必定是离散的,只有“是”或“否”。(即有目标和标签,能判断目标特征是属于哪一个类型) 回归(regression) 有监督学习的两大应用之一,产生连续的结果。 例如向模型输入人的各种数据
二clustering聚类也是分析样本的属性, 有点类似classification, 不同的就是classification 在预测之前是知道 的范围, 或者说知道到底有几个类别, 而聚类是不知道属性的范围的。所以 classification 也常常被称为 supervised learning, 而clustering就被称为unsupervised learning。 clustering 事先不知道样本的属性范围,只能凭...
Further a comparison between ClassificationViaClustering and ClassificationViaRegression is done using WEKA Tool. The accuracy of grades prediction is calculated with both the approaches and a graphical explanation is presented for the BE (Information Technology) Third Semester students....
This survey reviews AL query strategies for classification, regression, and clustering under the pool-based AL scenario. The query strategies under classification are further divided into: informative-based, representative-based, informative- and representative-based, and others. Also, more advanced query...

Classification vs Clustering in Machine Learning: A Comprehensive Guide Explore the key differences between Classification and Clustering in machine learning. Understand algorithms, use cases, and which technique to use for your data science project. ...
前面几章我们介绍了监督学习,包括从带标签的数据中学习的回归和分类算法。本章,我们讨论无监督学习算法,聚类(clustering)。聚类是用于找出不带标签数据的相似性的算法。我们将介绍K-Means聚类思想,解决一个图像压缩问题,然后对算法的效果进行评估。最后,我们把聚类和分类算法组合起来,解决一个半监督学习问题。
